Warning: To avoid personal injury, never get beneath the vehicle when it is supported by only by a jack. The jack provided with your vehicle is designed solely for raising the vehicle to remove and refit the roadwheels. Always use axle stands to support the vehicle when it becomes necessary to place your body underneath the vehicle. 7Being careful not to touch the hot exhaust components, place the drain pan under the drain plug, and unscrew the plug (see illustration). If possible, try to keep the plug pressed into the sump while unscrewing it by hand the last couple of turns. As the plug releases from the threads, move it away sharply, so the stream of oil issuing from the sump runs into the pan, not up your sleeve! Allow the oil to drain into the drain pan, and check the condition of the plug’s sealing washer; renew it if worn or damaged. 8Allow some time for the old oil to drain, noting that it may be necessary to reposition the pan as the oil flow slows to a trickle; when the oil has completely drained, wipe clean the drain plug and its threads in the sump and refit the plug, tightening it to the specified torque wrench setting. 9Using a suitable filter removal tool, unscrew the oil filter from the right-hand rear of the cylinder block; be prepared for some oil spillage (see illustration). Check the old filter to make sure that the rubber sealing ring hasn’t stuck to the engine; if it has, carefully remove it. Withdraw the filter through the wheel arch, taking care to spill as little oil as possible. 10Using a clean, lint-free rag, wipe clean the cylinder block around the filter mounting. If there are no specific instructions supplied with it, fit a new oil filter as follows. Apply a light coating of clean engine oil to the filter’s sealing ring (see illustration). Screw the filter into position on the engine until it seats, then tighten it through a further half- to three- quarters of a turn only. Tighten the filter by hand only - do not use any tools. 11Remove the old oil and all tools from under the vehicle, refit the roadwheel, and lower the vehicle to the ground.12Refill the engine with oil, using the correct grade and type of oil, as given in the Specifications Section of this Chapter. Pour in half the specified quantity of oil first, then wait a few minutes for the oil to fall to the sump. Continue adding oil a small quantity at a time, until the level is up to the lower notch on the dipstick. Adding approximately 0.5 to 1.0 litre will raise the level to the dipstick’s upper notch. 13Start the engine. The oil pressure warning light will take a few seconds to go out while the new filter fills with oil; do not race the engine while the light is on. Run the engine for a few minutes, while checking for leaks around the oil filter seal and the drain plug. 14Switch off the engine, and wait a few minutes for the oil to settle in the sump once more. With the new oil circulated and the filter now completely full, recheck the level on the dipstick, and add more oil as necessary. 15Dispose of the used engine oil safely, with reference to “General repair procedures”in the reference Sections of this manual. 1The manual transmission does not have a dipstick. To check the oil level, raise the vehicle and support it securely on axle stands, making sure that the vehicle is level. On the lower front side of the transmission housing,you will see the filler/level plug. Unscrew and remove it. If the lubricant level is correct, the oil should be up to the lower edge of the hole. 2If the transmission needs more lubricant (if the oil level is not up to the hole), use a syringe, or a plastic bottle and tube, to add more (see illustration). Stop filling the transmission when the lubricant begins to run out of the hole. 3Refit the filler/level plug, and tighten it to the specified torque wrench setting. Drive the vehicle a short distance, then check for leaks. 4A need for regular topping-up can only be due to a leak, which should be found and rectified without delay. The procedure is described in Chapter 8, Section 3. 1Apply the handbrake, then jack up the front of the vehicle and support on axle stands. Remove the left-hand front wheel. 2Apply a little oil to the cable end fitting on the selector lever on the left-hand side of the transmission (refer to Chapter 7, Part B if necessary). 3Refit the wheel, and lower the vehicle to the ground. Front suspension and steering check 1Apply the handbrake, then raise the front of the vehicle and support it on axle stands. 2Visually inspect the balljoint dust covers and the steering gear gaiters for splits, chafing or deterioration (see illustrations). Any wear 19 Steering, suspension and roadwheel check 18 Automatic transmission linkage lubrication 17 Clutch pedal adjustment 16 Manual transmission oil level check 1•17 1 19.2B Check the condition of the lower arm balljoint dust cover (arrowed) 15.10 Lubricate the filter’s sealing ring with clean engine oil before installing the filter on the engine16.2 Topping-up the manual transmission oil 19.2A Check the condition of the track rod balljoint dust cover (arrowed) Every 10 000 miles
of these components will cause loss of lubricant, together with dirt and water entry, resulting in rapid deterioration of the balljoints or steering gear. 3Check the power-assisted steering fluid hoses for chafing or deterioration, and the pipe and hose unions for fluid leaks. Also check for signs of fluid leakage under pressure from the steering gear rubber gaiters, which would indicate failed fluid seals within the steering gear. 4Grasp the roadwheel at the 12 o’clock and 6 o’clock positions, and try to rock it (see illustration). Very slight free play may be felt, but if the movement is appreciable, further investigation is necessary to determine the source. Continue rocking the wheel while an assistant depresses the footbrake. If the movement is now eliminated or significantly reduced, it is likely that the hub bearings are at fault. If the free play is still evident with the footbrake depressed, then there is wear in the suspension joints or mountings. 5Now grasp the wheel at the 9 o’clock and 3 o’clock positions, and try to rock it as before. Any movement felt now may again be caused by wear in the hub bearings or the steering track rod balljoints. If the outer track rod balljoint is worn, the visual movement will be obvious. If the inner joint is suspect, it can be felt by placing a hand over the rack-and- pinion rubber gaiter, and gripping the track rod. If the wheel is now rocked, movement will be felt at the inner joint if wear has taken place. 6Using a large screwdriver or flat bar, check for wear in the suspension mounting bushes by levering between the relevant suspension component and its attachment point. Some movement is to be expected as the mountings are made of rubber, but excessive wear should be obvious. Also check the condition of any visible rubber bushes, looking for splits, cracks or contamination of the rubber. 7With the vehicle standing on its wheels, have an assistant turn the steering wheel back-and-forth, about an eighth of a turn each way. There should be very little, if any, lost movement between the steering wheel and roadwheels. If this is not the case, closely observe the joints and mountings previouslydescribed, but in addition, check the steering column universal joints for wear, and also check the rack-and-pinion steering gear itself. Rear suspension check 8Chock the front wheels, then raise the rear of the vehicle and support it on axle stands. 9Check the rear hub bearings for wear, using the method described for the front hub bearings (paragraph 4). 10Using a large screwdriver or flat bar, check for wear in the suspension mounting bushes by levering between the relevant suspension component and its attachment point. Some movement is to be expected as the mountings are made of rubber, but excessive wear should be obvious. Roadwheel check and balancing 11Periodically remove the roadwheels, and clean any dirt or mud from the inside and outside surfaces. Examine the wheel rims for signs of rusting, corrosion or other damage. Light alloy wheels are easily damaged by “kerbing” whilst parking, and similarly, steel wheels may become dented or buckled. Renewal of the wheel is very often the only course of remedial action possible. 12The balance of each wheel and tyre assembly should be maintained, not only to avoid excessive tyre wear, but also to avoid wear in the steering and suspension components. Wheel imbalance is normally signified by vibration through the vehicle’s bodyshell, although in many cases it is particularly noticeable through the steering wheel. Conversely, it should be noted that wear or damage in suspension or steering components may cause excessive tyre wear. Out-of-round or out-of-true tyres, damaged wheels and wheel bearing wear/ maladjustment also fall into this category. Balancing will not usually cure vibration caused by such wear. 13Wheel balancing may be carried out with the wheel either on or off the vehicle. If balanced on the vehicle, ensure that the wheel-to-hub relationship is marked in some way prior to subsequent wheel removal, so that it may be refitted in its original position.1The driveshaft rubber gaiters are very important, because they prevent dirt, water and foreign material from entering and damaging the constant velocity (CV) joints. External contamination can cause the gaiter material to deteriorate prematurely, so it’s a good idea to wash the gaiters with soap and water occasionally. 2With the vehicle raised and securely supported on axle stands, turn the steering onto full-lock, then slowly rotate each front wheel in turn. Inspect the condition of the outer constant velocity (CV) joint rubber gaiters, squeezing the gaiters to open out the folds. Check for signs of cracking, splits, or deterioration of the rubber, which may allow the escape of grease, and lead to the ingress of water and grit into the joint (see illustration). Also check the security and condition of the retaining clips. Repeat these checks on the inner CV joints. If any damage or deterioration is found, the gaiters should be renewed as described in Chapter 8. 3At the same time, check the general condition of the outer CV joints themselves, by first holding the driveshaft and attempting to rotate the wheels. Repeat this check on the inner joints, by holding the inner joint yoke and attempting to rotate the driveshaft. 4Any appreciable movement in the CV joint indicates wear in the joint, wear in the driveshaft splines, or a loose driveshaft retaining nut. 1With the engine cold (at least three hours after the vehicle has been driven), check the complete exhaust system, from its starting point at the engine to the end of the tailpipe. Ideally, this should be done on a hoist, where unrestricted access is available; if a hoist is not available, raise and support the vehicle on axle stands. 2Check the pipes and connections for 21 Exhaust system check 20 Driveshaft rubber gaiter and CV joint check 1•18 19.2C Check the condition of the steering rack gaiters19.4 Checking for wear in the front suspension and hub bearings20.2 Check the driveshaft gaiters by hand for cracks and/or leaking grease Every 10 000 miles
evidence of leaks, severe corrosion, or damage. Make sure that all brackets and rubber mountings are in good condition, and tight; if any of the mountings are to be renewed, ensure that the replacements are of the correct type (see illustration). Leakage at any of the joints or in other parts of the system will usually show up as a black sooty stain in the vicinity of the leak. Note:Exhaust sealants should not be used on any part of the exhaust system upstream of the catalytic converter - even if the sealant does not contain additives harmful to the converter, pieces of it may break off and foul the element, causing local overheating. 3At the same time, inspect the underside of the body for holes, corrosion, open seams, etc. which may allow exhaust gases to enter the passenger compartment. Seal all body openings with silicone or body putty. 4Rattles and other noises can often be traced to the exhaust system, especially the rubber mountings. Try to move the system, silencer(s) and catalytic converter. If any components can touch the body or suspension parts, secure the exhaust system with new mountings. 5Check the running condition of the engine by inspecting inside the end of the tailpipe; the exhaust deposits here are an indication of the engine’s state of tune. The inside of the tailpipe should be dry, and should vary in colour from dark grey to light grey/brown; if it is black and sooty, or coated with white deposits, the engine is in need of a thorough fuel system inspection. 1With the vehicle raised and supported on axle stands or over an inspection pit, thoroughly inspect the underbody and wheel arches for signs of damage and corrosion. In particular, examine the bottom of the side sills, and any concealed areas where mud can collect. Where corrosion and rust is evident,press and tap firmly on the panel with a screwdriver, and check for any serious corrosion which would necessitate repairs. If the panel is not seriously corroded, clean away the rust, and apply a new coating of underseal. Refer to Chapter 11 for more details of body repairs. 2At the same time, inspect the PVC-coated lower body panels for stone damage and general condition. 3Inspect all of the fuel and brake lines on the underbody for damage, rust, corrosion and leakage. Also make sure that they are correctly supported in their clips. Where applicable, check the PVC coating on the lines for damage. Note:For detailed photographs of the brake system, refer to Chapter 9. 1The work described in this Section should be carried out at the specified intervals, or whenever a defect is suspected in the braking system. Any of the following symptoms could indicate a potential brake system defect: (a) The vehicle pulls to one side when the brake pedal is depressed. (b) The brakes make scraping or dragging noises when applied. (c) Brake pedal travel is excessive. (d) The brake fluid requires repeated topping- up. 2A brake pad wear warning light is fitted, and it is illuminated when the thickness of the front (or rear) disc brake pad linings reach the minimum amount. However, a physical check should be made to confirm the thickness of the linings, as follows. Disc brakes 3Jack up the front or rear of the vehicle, as applicable, and support it on axle stands. Where rear brake pads are fitted, also jack up the rear of the vehicle and support on axle stands. 4For better access to the brake calipers, remove the wheels. 5Look through the inspection window in thecaliper, and check that the thickness of the friction lining material on each of the pads is not less than the recommended minimum thickness given in the Specifications. Note: Bear in mind that the lining material is normally bonded to a metal backing plate. 6If it is difficult to determine the exact thickness of the pad linings, or if you are at all concerned about the condition of the pads, then remove them from the calipers for further inspection (refer to Chapter 9). 7Check the remaining brake caliper(s) in the same way. 8If any one of the brake pads has worn down to, or below, the specified limit, all fourpads at that end of the car must be renewed as a set (ie all the front pads or all the rear pads). 9Measure the thickness of the discs with a micrometer, if available, to make sure that they still have service life remaining. If any disc is thinner than the specified minimum thickness, renew it (refer to Chapter 9). In any case, check the general condition of the discs. Look for excessive scoring and discolouration caused by overheating. If these conditions exist, remove the relevant disc and have it resurfaced or renewed (refer to Chapter 9). 10Before refitting the wheels, check all brake lines and hoses (refer to Chapter 9). In particular, check the flexible hoses in the vicinity of the calipers, where they are subjected to most movement. Bend them between the fingers (but do not actually bend them double, or the casing may be damaged) and check that this does not reveal previously-hidden cracks, cuts or splits (see illustration). Rear drum brakes 11Chock the front wheels, then jack up the rear of the vehicle and support on axle stands. 12For better access, remove the rear wheels. 13To check the brake shoe lining thickness without removing the brake drums, prise the rubber plugs from the backplates, and use an electric torch to inspect the linings of the leading brake shoes (see illustration). Check that the thickness of the lining material on the 23 Brake check 22 Underbody and fuel/brake line check 1•19 121.2 If any of the exhaust system rubber mountings are to be renewed, ensure that the replacements are of the correct type - their colour is a good guide. Those nearest to the catalytic converter are more heat- resistant than the others23.10 Checking the condition of a flexible brake hose23.13 Prise the rubber plugs from the backplates to inspect the leading brake shoe linings Every 000 miles
brake shoes is not less than the recommendation given in the Specifications. 14If it is difficult to determine the exact thickness of the brake shoe linings, or if you are at all concerned about the condition of the shoes, then remove the rear drums for a more comprehensive inspection (refer to Chapter 9) (see illustration). 15With the drum removed, check the shoe return and hold-down springs for correct installation, and check the wheel cylinders for leakage of brake fluid. Check the friction surface of the brake drums for scoring and discoloration. If excessive, the drum should be resurfaced or renewed. 16Before refitting the wheels, check all brake lines and hoses (refer to Chapter 9). On completion, apply the handbrake and check that the rear wheels are locked. The handbrake is self-adjusting, and no manual adjustment is possible. 1Check that the doors, bonnet and tailgate/boot lid close securely. Check that the bonnet safety catch operates correctly. Check the operation of the door check straps. 2Lubricate the hinges, door check straps, the striker plates and the bonnet catch sparingly with a little oil or grease.1Apply the handbrake. 2Remove the wheel covers, using the flat end of the wheelbrace supplied in the tool kit (on models with the RS trim kit, it will be necessary to unscrew the retaining bolts with the special key). 3Check that the roadwheel nuts are tightened to the specified torque wrench setting. 4Refit the wheel covers. Check the operation and performance of the braking system 1Make sure that the vehicle does not pull to one side when braking, and that the wheels do not lock prematurely when braking hard. 2Check that there is no vibration through the steering when braking. 3Check that the handbrake operates correctly, without excessive movement of the lever, and that it holds the vehicle stationary on a slope. 4With the engine switched off, test the operation of the brake servo unit as follows. Depress the footbrake four or five times to exhaust the vacuum, then start the engine. As the engine starts, there should be a noticeable “give” in the brake pedal as vacuum builds up. Allow the engine to run for at least two minutes, and then switch it off. If the brake pedal is now depressed again, it should be possible to detect a hiss from the servo as the pedal is depressed. After about four or five applications, no further hissing should be heard, and the pedal should feel considerably harder. Steering and suspension 5Check for any abnormalities in the steering, suspension, handling or road “feel”. 6Drive the vehicle, and check that there are no unusual vibrations or noises. 7Check that the steering feels positive, with no excessive sloppiness or roughness, andcheck for any suspension noises when cornering and driving over bumps. Drivetrain 8Check the performance of the engine, transmission and driveshafts. 9Check that the engine starts correctly, both when cold and when hot. 10Listen for any unusual noises from the engine and transmission. 11Make sure that the engine runs smoothly when idling, and that there is no hesitation when accelerating. 12On manual transmission models, check that all gears can be engaged smoothly without noise, and that the gear lever action is not abnormally vague or “notchy”. 13On automatic transmission models, make sure that all gearchanges occur smoothly without snatching, and without an increase in engine speed between changes. Check that all the gear positions can be selected with the vehicle at rest. If any problems are found, they should be referred to a Ford dealer. 14Listen for a metallic clicking sound from the front of the vehicle as the vehicle is driven slowly in a circle with the steering on full-lock. Carry out this check in both directions. If a clicking noise is heard, this indicates wear in a driveshaft joint, in which case renew the joint if necessary. Clutch 15Check that the clutch pedal moves smoothly and easily through its full travel, and that the clutch itself functions correctly, with no trace of slip or drag. If the movement is uneven or stiff in places, check that the cable is routed correctly, with no sharp turns. 16Inspect both ends of the clutch inner cable, both at the gearbox end and inside the car, for signs of wear and fraying. 17Check the pedal stroke as described in Chapter 8, Section 3, and adjust if necessary. Instruments and electrical equipment 18Check the operation of all instruments and electrical equipment. 19Make sure that all instruments read correctly, and switch on all electrical equipment in turn, to check that it functions properly. 26 Road test 25 Roadwheel nut tightness check 24 Door and bonnet check and lubrication 1•20 23.14 If the lining is bonded to the brake shoe, measure the lining thickness from the outer surface to the metal shoe, as shown here; if the lining is riveted to the shoe, measure from the lining outer surface to the rivet head Every 20 000 miles Every 20 000 miles or 2 years 1The air entering the vehicle’s ventilation system is passed through a very fine pleated- paper air filter element, which removes particles of pollen, dust and other airborne foreign matter. To ensure its continued effectiveness, this filter’s element must be renewed at regular intervals.2Remove the left-hand side windscreen wiper arm (Chapter 12). 3Prise off their trim caps, then unscrew the two screws securing the windscreen edge of the cowl grille panel; open the bonnet and remove the remaining three retaining screws (see illustration). 4Peel back the rubber seal and withdraw the cowl grille panel. 5Releasing the clip at each end, lift out the pollen filter housing, and withdraw the element (see illustrations).6Wipe out the ventilation system intake and the filter housing, removing any leaves, dead insects etc. 7If carrying out a routine service, the element must be renewed regardless of its apparent condition. If you are checking the element for any other reason, inspect its front surface; if it is very dirty, renew the element. If it is only moderately dusty, it can be re-used by blowing it clean from the rear to the front surface with compressed air. Because it is a 27 Ventilation system pollen filter renewal
pleated-paper type filter, it cannot be washed or re-oiled. If it cannot be cleaned satisfactorily with compressed air, discard and renew it. Warning: Wear eye protection when using compressed air! 8Refitting is the reverse of the removal procedure; ensure that the element and housing are securely seated, so that unfiltered air cannot enter the passenger compartment. Note:If the antifreeze used is Ford’s own, or of similar quality, the coolant need not be renewed for the life of the vehicle. If the vehicle’s history is unknown, if antifreeze of lesser quality is known to be in the system, or simply if you prefer to follow conventional servicing intervals, the coolant should be changed periodically (typically, every 2 years) as described here. Refer also to the information in Section 2 of this Chapter. Warning: Do not allow antifreeze to come in contact with your skin or painted surfaces of the vehicle. Flush contaminated areas immediately with plenty of water. Don’t store new coolant, or leave old coolant lying around, where it’s accessible to children or pets - they’re attracted by its sweet smell. Ingestion of even a small amount of coolant can be fatal! Wipe up garage-floor and drip-pan spills immediately. Keep antifreeze containers covered, and repair cooling system leaks as soon as they’re noticed. Warning: Never remove the expansion tank filler cap when the engine is running, or has just been switched off, as the cooling system will be hot, and the consequent escaping steam and scalding coolant could cause serious injury. Coolant draining Warning: Wait until the engine is cold before starting this procedure.1To drain the system, first remove the expansion tank filler cap (see Section 3). 2If the additional working clearance is required, raise the front of the vehicle and support it securely on axle stands. 3Remove the radiator undershield (eight or nine screws), then place a large drain tray underneath, and unscrew the radiator drain plug; direct as much of the escaping coolant as possible into the tray (see illustrations). System flushing 4With time, the cooling system may gradually lose its efficiency, as the radiator core becomes choked with rust, scale deposits from the water, and other sediment (refer also to the information at the start of Section 2). To minimise this, as well as using only good-quality antifreeze and clean soft water, the system should be flushed as follows whenever any part of it is disturbed, and/or when the coolant is renewed. 5With the coolant drained, refit the drain plug and refill the system with fresh water. Refit the expansion tank filler cap, start the engine and warm it up to normal operating temperature, then stop it and (after allowing it to cool down completely) drain the system again. Repeat as necessary until only clean water can be seen to emerge, then refill finally with the specified coolant mixture. 6If only clean, soft water and good-quality antifreeze (even if not to Ford’s specification) has been used, and the coolant has been renewed at the suggested intervals, the above procedure will be sufficient to keep clean the system for a considerable length of time. If,however, the system has been neglected, a more thorough operation will be required, as follows. 7First drain the coolant, then disconnect the radiator top and bottom hoses. Insert a garden hose into the top hose, and allow water to circulate through the radiator until it runs clean from the bottom outlet. 8To flush the engine, insert the garden hose into the thermostat water outlet, and allow water to circulate until it runs clear from the bottom hose. If, after a reasonable period, the water still does not run clear, the radiator should be flushed with a good proprietary cleaning agent. 9In severe cases of contamination, reverse- flushing of the radiator may be necessary. To do this, remove the radiator (Chapter 3), invert it, and insert the garden hose into the bottom outlet. Continue flushing until clear water runs from the top hose outlet. A similar procedure can be used to flush the heater matrix. 10The use of chemical cleaners should be necessary only as a last resort. Normally, regular renewal of the coolant will prevent excessive contamination of the system. Coolant filling 11With the cooling system drained and flushed, ensure that all disturbed hose unions 28 Coolant renewal 1•21 1 28.3A Remove the screws (arrowed) and withdraw the radiator undershield . . . 28.3B . . . to unscrew the radiator drain plug (arrowed) and empty the cooling system.

are correctly secured, and that the radiator drain plug is securely tightened. Refit the radiator undershield, noting that it is located by three clips at its front edge; tighten the retaining screws securely (see illustration). If it was raised, lower the vehicle to the ground. 12Prepare a sufficient quantity of the specified coolant mixture (see below); allow for a surplus, so as to have a reserve supply for topping-up. 13Slowly fill the system through the expansion tank; since the tank is the highest point in the system, all the air in the system should be displaced into the tank by the rising liquid. Slow pouring reduces the possibility of air being trapped and forming air-locks. 14Continue filling until the coolant level reaches the expansion tank “MAX” level line, then cover the filler opening to prevent coolant splashing out. 15Start the engine and run it at idle speed, until it has warmed-up to normal operating temperature and the radiator electric cooling fan has cut in; watch the temperature gauge to check for signs of overheating. If the level in the expansion tank drops significantly, top-up to the “MAX” level line, to minimise the amount of air circulating in the system. 16Stop the engine, allow it to cool down completely(overnight, if possible), then uncover the expansion tank filler opening and top-up the tank to the “MAX” level line. Refit the filler cap, tightening it securely, and washoff any spilt coolant from the engine compartment and bodywork. 17After refilling, always check carefully all components of the system (but especially any unions disturbed during draining and flushing) for signs of coolant leaks. Fresh antifreeze has a searching action, which will rapidly expose any weak points in the system. 18 Note:If, after draining and refilling the system, symptoms of overheating are found which did not occur previously, then the fault is almost certainly due to trapped air at some point in the system, causing an air-lock and restricting the flow of coolant; usually, the air is trapped because the system was refilled too quickly. In some cases, air-locks can be released by tapping or squeezing the various hoses. If the problem persists, stop the engine and allow it to cool down completely, before unscrewing the expansion tank filler cap or disconnecting hoses to bleed out the trapped air. Antifreeze mixture 19If the antifreeze used is not to Ford’s specification, it should always be renewed at the suggested intervals. This is necessary not only to maintain the antifreeze properties, but also to prevent the corrosion which would otherwise occur as the corrosion inhibitors become progressively less effective. Always use an ethylene glycol-based antifreeze which is suitable for use in mixed-metal cooling systems. 20If the antifreeze used is to Ford’s specification, the levels of protection it affords are indicated in the Specifications Section of this Chapter. To give the recommended standardmixture ratio for this antifreeze, 40% (by volume) of antifreeze must be mixed with 60% of clean, soft water; if you are using any other type of antifreeze, follow its manufacturer’s instructions to achieve the correct ratio. It is best to make up slightly more than the system’s specified capacity, so that a supply is available for subsequent topping-up. 21Before adding antifreeze, the cooling system should be completely drained, preferably flushed, and all hoses checked forcondition and security. As noted earlier, fresh antifreeze will rapidly find any weaknesses in the system. 22After filling with antifreeze, a label should be attached to the expansion tank, stating the type and concentration of antifreeze used, and the date installed. Any subsequent topping-up should be made with the same type and concentration of antifreeze. If topping-up using antifreeze to Ford’s specification, note that a 50/50 mixture is permissible, purely for convenience. 23Do not use engine antifreeze in the windscreen/tailgate washer system, as it will damage the vehicle’s paintwork. A screen wash additive should be added to the washer system in its maker’s recommended quantities. General cooling system checks 24The engine should be cold for the cooling system checks, so perform the following procedure before driving the vehicle, or after it has been shut off for at least three hours. 25Remove the expansion tank filler cap (see Section 3), and clean it thoroughly inside and out with a rag. Also clean the filler neck on the expansion tank. The presence of rust or corrosion in the filler neck indicates that the coolant should be changed. The coolant inside the expansion tank should be relatively clean and transparent. If it is rust- coloured, drain and flush the system, and refill with a fresh coolant mixture. 26Carefully check the radiator hoses and heater hoses along their entire length; renew any hose which is cracked, swollen or deteriorated (see Section 12). 27Inspect all other cooling system components (joint faces, etc.) for leaks. A leak in the cooling system will usually show up as white- or rust-coloured deposits on the area adjoining the leak. Where any problems of this nature are found on system components, renew the component or gasket with reference to Chapter 3. 28Clean the front of the radiator with a soft brush to remove all insects, leaves, etc, embedded in the radiator fins. Be careful not to damage the radiator fins, or cut your fingers on them. 1•22 28.11 Ensure radiator undershield is located securely in three clips at front edge (arrowed) when refitting Every 30 000 miles Every 30 000 miles or 3 years 1The air filter element is located in the air cleaner assembly on the left-hand side of the engine compartment. Release the clips, and lift the air cleaner cover (see illustrations). If the additional working clearance is required, unclip the cover from the air mass meter, and withdraw it completely. 2Lift out the element, and wipe out thehousing (see illustration). Check that no foreign matter is visible, either in the air intake or in the air mass meter. 3If carrying out a routine service, the element must be renewed regardless of its apparent condition; note that the small foam filter in the rear right-hand corner of the air cleaner housing must be cleaned whenever the air filter element is renewed (see Section 30). 4If you are checking the element for any other reason, inspect its lower surface; if it is oily or very dirty, renew the element. If it is only moderately dusty, it can be re-used byblowing it clean from the upper to the lower surface with compressed air. Because it is a pleated-paper type filter, it cannot be washed or re-oiled. If it cannot be cleaned satisfactorily with compressed air, discard and renew it. Warning: Wear eye protection when using compressed air! Caution: Never drive the vehicle with the air cleaner filter element removed. Excessive engine wear could result, and backfiring could even cause a fire under the bonnet. 29 Air filter element renewal
5Refitting is the reverse of the removal procedure. Ensure that the element and cover are securely seated, so that unfiltered air cannot enter the engine. 1The Positive Crankcase Ventilation (PCV) system components are located at the front of the engine, underneath the exhaust manifold and air intake resonator. Refer to Chapter 6 for further information. 2Check that all components of the system are securely fastened, correctly routed (with no kinks or sharp bends to restrict flow) and in sound condition; renew any worn or damaged components. 3If oil leakage is noted, disconnect the various hoses and pipes, and check that all are clear and unblocked. Remove the air cleaner assembly cover, air mass meter and resonator, then check that the hose from the cylinder head cover to the air cleaner housing is clear and undamaged. Disconnect the rubber T-piece both from the union on the inlet manifold left-hand end, and from the metal crankcase breather pipe under the ignition coil. Connect a spare, clean, length of hose to the breather pipe. Suck on the end of the hose, then blow through it - little or norestriction to airflow should be felt in either direction. A similar test can be applied to check that the inlet manifold passages are clear - air should be heard hissing out of the plenum chamber mouth as you blow. 4The PCV valve is designed to allow gases to flow out of the crankcase only, so that a depression is created in the crankcase under most operating conditions, particularly at idle. Therefore, if either the oil separator or the PCV valve are thought to be blocked, they must be renewed (see Chapter 6). In such a case, however, there is nothing to be lost by attempting to flush out the blockage using a suitable solvent. The PCV valve should rattle when shaken. 5While the air filter element is removed (see Section 29), wipe out the housing, and withdraw the small foam filter from its location in the rear right-hand corner of the housing (see illustration). If the foam is badly clogged with dirt or oil, it must be cleaned by soaking it in a suitable solvent, and allowed to dry before being refitted. Spark plug check and renewal 1It is vital for the correct running, full performance and proper economy of the engine that the spark plugs perform with maximum efficiency. The most important factor in ensuring this is that the plugs fitted are appropriate for the engine. The suitable type is given in the Specifications Section at the beginning of this Chapter, on the Vehicle Emissions Control Information (VECI) label located on the underside of the bonnet (only on models sold in some areas) or in the vehicle’s Owner’s Handbook. If these sources specify different plugs, purchase the spark plug type specified on the VECI label (where appropriate), as that information is provided specifically for your engine. If this type is used and the engine is in good condition, the spark plugs should not need attention between scheduled renewal intervals. Spark plug cleaning is rarely necessary, and should notbe attempted unless specialised equipment is available, as damage can easily be caused to the firing ends. 2Spark plug removal and refitting requires a spark plug socket, with an extension which can be turned by a ratchet handle or similar. This socket is lined with a rubber sleeve, to protect the porcelain insulator of the spark plug, and to hold the plug while you insert it into the spark plug hole. You will also need a wire-type feeler gauge, to check and adjust the spark plug electrode gap, and a torque wrench to tighten the new plugs to the specified torque (see illustration). 3To remove the spark plugs, first open the bonnet; the plugs are easily reached at the top of the engine. Note how the spark plug (HT) leads are routed and secured by clips along the channel in the cylinder head cover. 31 Spark plug renewal 30 Positive Crankcase Ventilation (PCV) system check and filter cleaning 1•23 1 30.5 The Positive Crankcase Ventilation (PCV) system filter in the air cleaner assembly must be cleaned whenever the air filter element is renewed 31.2 Tools required for changing spark plugs 1Spark plug socket- This will have special padding inside, to protect the spark plug porcelain insulator 2Torque wrench- Although not essential, use of this tool is the best way to ensure that the plugs are tightened properly 3Ratchet- Standard hand tool to fit the plug socket 4Extension- Depending on the other tools available, you may need an extension to reach the plugs 5Spark plug gap gauge- This gauge for checking the gap comes in a variety of styles.

To prevent the possibility of mixing up spark plug (HT) leads, it is a good idea to try to work on one spark plug at a time. 4If the marks on the original-equipment spark plug (HT) leads cannot be seen, mark the leads 1 to 4, to correspond to the cylinder the lead serves (No 1 cylinder is at the timing belt end of the engine). Pull the leads from the plugs by gripping the rubber boot sealing thecylinder head cover opening, not the lead, otherwise the lead connection may be fractured. 5It is advisable to soak up any water in the spark plug recesses with a rag, and to remove any dirt from them using a clean brush, vacuum cleaner or compressed air before removing the plugs, to prevent any dirt or water from dropping into the cylinders. Warning: Wear eye protection when using compressed air! 6Unscrew the spark plugs, ensuring that the socket is kept in alignment with each plug - if the socket is forcibly moved to either side, the porcelain top of the plug may be broken off. If any undue difficulty is encountered when unscrewing any of the spark plugs, carefully 1•24Every 30 000 miles Specifications Engine Direction of crankshaft rotation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

check the cylinder head threads and tapered sealing surfaces for signs of wear, excessive corrosion or damage; if any of these conditions is found, seek the advice of a Ford dealer as to the best method of repair. 7As each plug is removed, examine it as follows - this will give a good indication of the condition of the engine. If the insulator nose of the spark plug is clean and white, with no deposits, this is indicative of a weak mixture. 8If the tip and insulator nose are covered with hard black-looking deposits, then this is indicative that the mixture is too rich. Should the plug be black and oily, then it is likely that the engine is fairly worn, as well as the mixture being too rich. 9If the insulator nose is covered with light tan to greyish-brown deposits, then the mixture is correct, and it is likely that the engine is in good condition. 10If you are renewing the spark plugs, purchase the new plugs, then check each of them first for faults such as cracked insulators or damaged threads. Note also that, whenever the spark plugs are renewed as a routine service operation, the spark plug (HT) leads should be checked as described below. 11The spark plug electrode gap is of considerable importance as, if it is too large or too small, the size of the spark and its efficiency will be seriously impaired. The gap should be set to the value given in the Specifications Section of this Chapter. New plugs will not necessarily be set to the correct gap, so they should always be checked before fitting. 12Special spark plug electrode gap adjusting tools are available from most motor accessory shops (see illustration). 13To set the electrode gap, measure the gap with a feeler gauge, and then bend open, or closed, the outer plug electrode until the correct gap is achieved (see illustration). The centre electrode should never be bent, as this may crack the insulation and cause plug failure, if nothing worse. If the outer electrode is not exactly over the centre electrode, bend it gently to align them.14Before fitting the spark plugs, check that the threaded connector sleeves at the top of the plugs are tight, and that the plug exterior surfaces and threads are clean. Brown staining on the porcelain, immediately above the metal body, is quite normal, and does not necessarily indicate a leak between the body and insulator. 15On installing the spark plugs, first check that the cylinder head thread and sealing surface are as clean as possible; use a clean rag wrapped around a paintbrush to wipe clean the sealing surface. Apply a smear of copper-based grease or anti-seize compound to the threads of each plug, and screw them in by hand where possible. Take extra care to enter the plug threads correctly, as the cylinder head is of aluminium alloy - it’s often difficult to insert spark plugs into their holes without cross-threading them. 16When each spark plug is started correctly on its threads, screw it down until it just seats lightly, then tighten it to the specified torquewrench setting (see illustration). If a torque wrench is not available - and this is one case where the use of a torque wrench is strongly recommended - tighten each spark plug through no more than1/16 of a turn. Do not exceed the specified torque setting, and NEVERovertighten these spark plugs - their tapered seats mean they are almost impossible to remove if abused. 17Reconnect the spark plug (HT) leads in their correct order, using a twisting motion on the boot until it is firmly seated on the end of the spark plug and on the cylinder head cover. Spark plug (HT) lead check 18The spark plug (HT) leads should be checked whenever the plugs themselves are renewed. Start by making a visual check of the leads while the engine is running. In a darkened garage (make sure there is ventilation) start the engine and observe each lead. Be careful not to come into contact with any moving engine parts. If there is a break in the lead, you will see arcing or a small spark at the damaged area. 19The spark plug (HT) leads should be inspected one at a time, to prevent mixing up the firing order, which is essential for proper engine operation. Each original lead should be numbered to identify its cylinder. If the number is illegible, a piece of tape can be marked with the correct number, and wrapped around the lead (the leads should be numbered 1 to 4, with No 1 lead nearest the timing belt end of the engine). The lead can then be disconnected. 20Check inside the boot for corrosion, which will look like a white crusty powder. Clean this off as much as possible; if it is excessive, or if cleaning leaves the metal connector too badly corroded to be fit for further use, the lead must be renewed. Push the lead and boot back onto the end of the spark plug. The boot should fit tightly onto the end of the plug - if it doesn’t, remove the lead and use pliers carefully to crimp the metal connector inside the boot until the fit is snug. 21Using a clean rag, wipe the entire length of 1•25 1 Every 30 000 miles 31.12 Spark plug manufacturers recommend using a wire-type gauge when checking the gap - if the wire does not slide between the electrodes with a slight drag, adjustment is required31.13 To change the gap, bend the outer electrode only, as indicated by the arrows, and be very careful not to crack or chip the porcelain insulator surrounding the centre electrode31.16 Spark plugs have tapered seats - do not overtighten them on refitting, or you will not be able to get them out again without risking damage to the plugs and cylinder head To avoid the possibility of cross- threading a spark plug, fit a short piece of rubber hose over the end of the plug. The flexible hose acts as a universal joint, to help align the plug with the plug hole. Should the plug begin to cross-thread, the hose will slip on the spark plug, preventing thread damage.
1•26Every 60 000 miles Every 60 000 miles Refer to Chapter 2, Part A. Warning: Petrol is extremely flammable, so extra precautions must be taken when working on any part of the fuel system. Do not smoke, or allow open flames or bare light bulbs, near the work area. Also, do not work in a garage if a gas appliance with a pilot light is present. While performing any work on the fuel system, wear safety glasses, and have a suitable (Class B) fire extinguisher on hand. If you spill any fuel on your skin, rinse it off immediately with soap and water. 1The fuel filter is located at the front right- hand corner of the fuel tank, just forward of the vehicle’s right-hand rear jacking point. The filter performs a vital role in keeping dirt and other foreign matter out of the fuel system, and so must be renewed at regular intervals,or whenever you have reason to suspect that it may be clogged. It is always unpleasant working under a vehicle - pressure-washing or hosing clean the underbody in the filter’s vicinity will make working conditions more tolerable, and will reduce the risk of getting dirt into the fuel system. 2Relieve any residual pressure in the system by removing the fuel pump fuse (No 14) and starting the engine; allow the engine to idle until it dies. Turn the engine over once or twice on the starter, to ensure that all pressure is released, then switch off the ignition. Warning: This procedure will merely relieve the pressure necessary for the engine to run - remember that fuel will still be present in the system components, and take precautions before disconnecting them. 3Noting the comments made in Section 1 of Chapter 5, disconnect the battery earth terminal. 4Jack up the rear right-hand side of the vehicle, and support it securely on an axle stand. 5Using rag to soak up any spilt fuel, release the fuel feed and outlet pipe unions from the filter, by squeezing together the protruding locking lugs on each union, and carefully pulling the union off the filter stub (seeillustration). Where the unions are colour- coded, the feed and outlet pipes cannot be confused; where both unions are the same colour, note carefully which pipe is connected to which filter stub, and ensure that they are correctly reconnected on refitting. 6Noting the arrows and/or other markings on the filter showing the direction of fuel flow (towards the engine), slacken the filter clamp screw and withdraw the filter. Note that the filter will still contain fuel; care should be taken, to avoid spillage and to minimise the risk of fire. 7On installation, slide the filter into its clamp so that the arrow marked on it faces the correct way, then slide each pipe union on to its (correct) respective filter stub, and press it down until the locking lugs click into their groove (see illustrations). Tighten the clamp screw carefully, until the filter is just prevented from moving; do not overtighten the clamp screw, or the filter casing may be crushed. 8Refit the fuel pump fuse and reconnect the battery earth terminal, then switch the ignition on and off five times, to pressurise the system. Check for any sign of fuel leakage around the filter unions before lowering the vehicle to the ground and starting the engine. 33 Fuel filter renewal 32 Timing belt renewal 33.5 Squeeze together fuel filter pipe union locking lugs, then pull pipes off filter stubs - ensure pipes are correctly reconnected33.7A When installing the new filter, ensure the arrow showing direction of fuel flow points towards the engine . . . Every 3 years The procedure is similar to that for the bleeding of the hydraulic system as described in Chapter 9, except that the brake fluid reservoir should be emptied by syphoning,and allowance should be made for the old fluid to be removed from the circuit when bleeding a section of the circuit. 34 Brake fluid renewal 31.22 Measure the resistance of the spark plug leads - if any exceeds the specified maximum value, renew all the leads the lead to remove built-up dirt and grease. Once the lead is clean, check for burns, cracks and other damage. Do not bend the lead sharply, because the conductor might break. 22Disconnect the lead from the ignition coil by pressing together the plastic retaining catches and pulling the end fitting off the coil terminal. Check for corrosion and for a tight fit. If a meter with the correct measuring range is available, measure the resistance of the disconnected lead from its coil connector to its spark plug connector (see illustration). If the resistance recorded for any of the leads exceeds the value specified, all the leadsshould be renewed as a set. Refit the lead to the coil, noting that each coil terminal is marked with its respective cylinder number, so that there is no risk of mixing up the leads and upsetting the firing order. 23Inspect the remaining plug leads, ensuring that each is securely fastened both ends when the check is complete. If any sign of arcing, severe connector corrosion, burns, cracks or other damage is noticed, obtain new spark plug (HT) leads, renewing them as a set. If new spark plug leads are to be fitted, remove and refit them one at a time, to avoid mix-ups in the firing order. 33.7B . . . secure pipe unions as described - do not overtighten clamp screw (arrowed)
