cylinder head cover; unscrew it to add oil (see illustration). When topping-up, use only the correct grade and type of oil, as given in the Specifications Section of this Chapter; use a funnel if necessary to prevent spills. It takes approximately 0.5 to 1.0 litre of oil to raise the level from the dipstick’s minimum level notch to its maximum level notch. After adding the oil, refit the filler cap hand-tight. Start the engine, and allow it to idle while the oil is redistributed around the engine - while you are waiting, look carefully for any oil leaks, particularly around the oil filter or drain plug. Stop the engine; check the oil level again, after the oil has had enough time to drain from the upper block and cylinder head galleries. 7Checking the oil level is an important preventive maintenance step. A continually- dropping oil level indicates oil leakage through damaged seals and from loose connections, or oil consumption past worn piston rings or valve guides. If the oil looks milky in colour, or has water droplets in it, the cylinder head gasket may be blown - the engine’s compression pressure should be checked immediately (see Chapter 2A). The condition of the oil should also be checked. Each time you check the oil level, slide your thumb and index finger up the dipstick before wiping off the oil. If you see small dirt or metal particles clinging to the dipstick, the oil should be changed (Section 15). Coolant 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.8All vehicles covered by this manual are equipped with a sealed, pressurised cooling system. A translucent plastic expansion tank, located on the right-hand side of the engine compartment, is connected by a hose to the thermostat housing. As the coolant heats up during engine operation, surplus coolant passes through the connecting hose into the expansion tank; a connection to the radiator bottom hose union allows coolant to circulate through the tank and back to the water pump, thus purging any air from the system. As the engine cools, the coolant is automatically drawn back into the cooling system’s main components, to maintain the correct level. 9While the coolant level must be checked regularly, remember therefore that it will vary with the temperature of the engine. When the engine is cold, the coolant level should be between the “MAX” and “MIN” level lines on the tank, but once the engine has warmed up, the level may rise to above the “MAX” level line. 10For an accurate check of the coolant level, the engine must be cold. The level must be between the “MAX” and “MIN” level lines on the tank (see illustration). If it is below the “MIN” level line, the coolant must be topped- up as follows. 11First prepare a sufficient quantity of coolant mixture, using clean, soft water and antifreeze of the recommended type, in the specified mixture ratio. If you are using antifreeze to Ford’s specification or equivalent (see the note at the beginning of Section 2 of this Chapter), mix equal quantities of water and antifreeze to produce the 50/50 mixture ratio specified when topping-up; if using any other type of antifreeze, follow its manufacturer’s instructions to achieve the correct ratio. If only a small amount of coolant is required to bring the system up to the proper level, plain water can be used, but repeatedly doing this will dilute the antifreeze/water solution in the system, reducing the protection it should provide against freezing and corrosion. To maintainthe specified antifreeze/water ratio, it is essential to top-up the coolant level with the correct mixture, as described here. Use only ethylene/glycol type antifreeze, and do not use supplementary inhibitors or additives. 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. 12If topping-up is necessary, wait until the system has cooled completely (or at least 10 minutes after switching off the engine, if lack of time means it is absolutely necessary to top-up while the engine may still be warm). Wrap a thick cloth around the expansion tank filler cap, and unscrew it one full turn. If any hissing is heard as steam escapes, wait until the hissing ceases, indicating that pressure is released, then slowly unscrew the filler cap until it can be removed. If more hissing sounds are heard, wait until they have stopped before unscrewing the filler cap completely. At all times, keep your face, hands and other exposed skin well away from the filler opening. 13When the filler cap has been removed, add coolant to bring the level up to the “MAX” level line (see illustration). Refit the cap, tightening it securely. 14With this type of cooling system, the addition of coolant should only be necessary at very infrequent intervals. If topping-up is regularly required, or if the coolant level drops within a short time after replenishment, there may be a leak in the system. Inspect the radiator, hoses, expansion tank filler cap, radiator drain plug and water pump. If no leak is evident, have the filler cap and the entire system pressure-tested by your dealer or suitably-equipped garage; this will usually show up a small leak not otherwise visible. If significant leakage is found at any time, use an antifreeze hydrometer to check the con- centration of antifreeze remaining in the coolant. 1•7 13.13 Remove the cap to add coolant only when the engine is cold - top-up to the “MAX” level line using the specified coolant mixture3.6 The yellow/black oil filler cap is screwed into the cylinder head cover. Always make sure the area around the opening is clean before unscrewing the cap, to prevent dirt from contaminating the engine3.10 The cooling system expansion tank is located on the right-hand side of the engine compartment. The coolant level must be between the tank “MAX” and “MIN” level lines (arrowed) when the engine is cold Weekly checks
15Coolant hydrometers are available at most automotive accessory shops. If the specific gravity of a sample taken from the expansion tank (when the engine is switched off and fully cooled down) is less than that specified, the coolant mixture strength has fallen below the minimum. If this is found, either the coolant strength must be restored by adding neat antifreeze to Ford’s specification (if that is what is in the system) or by draining and flushing the system, then refilling it with fresh coolant mixture of the correct ratio (if any other type of antifreeze is being used). 16When checking the coolant level, always note its condition; it should be relatively clear. If it is brown or rust-coloured, the system should be drained, flushed and refilled. If antifreeze has been used which does not meet Ford’s specification, its corrosion inhibitors will lose their effectiveness with time; such coolant must be renewed regularly, even if it appears to be in good condition, usually at the intervals suggested at the beginning of Section 2 of this Chapter. Windscreen/tailgate and headlight washer fluid 17Fluid for the windscreen/tailgate washer system (and where applicable the headlight washer system) is stored in a plastic reservoir, which is located at the right front corner of the engine compartment. In milder climates, plain water can be used to top-up the reservoir, but the reservoir should be kept no more than two-thirds full, to allow for expansion should the water freeze. In colder climates, the use of a specially-formulated windscreen washer fluid, available at your dealer or any car accessory shop, will help lower the freezing point of the fluid (see illustration). Do notuse regular (engine) antifreeze - it will damage the vehicle’s paintwork. Battery electrolyte 18On models not equipped with a sealed battery (see Section 9), check the electrolyte level of all six battery cells. The level must be approximately 10 mm above the plates; this may be shown by maximum and minimum level lines marked on the battery’s casing (seeillustration). If the level is low, use a coin to release the filler/vent cap, and add distilled water. Install and securely retighten the cap. Caution: Overfilling the cells may cause electrolyte to spill over during periods of heavy charging, causing corrosion or damage. Refer also to the warning at the beginning of Section 9. Brake fluid 19The brake fluid reservoir is located on the top of the brake master cylinder, which is attached to the front of the vacuum servo unit. The “MAX” and “MIN” marks are indicated on the side of the translucent reservoir, and the fluid level should be maintained between these marks at all times (see illustration). 20The brake fluid inside the reservoir is readily visible. With the vehicle on level ground, the level should normally be on or just below the “MAX” mark. 21Progressive wear of the brake pads and brake shoe linings causes the level of the brake fluid to gradually fall; however, when the brake pads are renewed, the original level of the fluid is restored. It is not therefore necessary to top-up the level to compensate for this minimal drop, but the level must never be allowed to fall below the minimum mark. 22If topping-up is necessary, first wipe the area around the filler cap with a clean rag before removing the cap. When adding fluid, pour it carefully into the reservoir, to avoid spilling it on surrounding painted surfaces (see illustration). Be sure to use only the specified hydraulic fluid (see “Lubricants, fluids and capacities”at the start of this Chapter) since mixing different types of fluid can cause damage to the system. Warning: Brake hydraulic fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it. Wash off spills immediately with plenty of water. Do not use fluid that has been standing open for some time, as it absorbs moisture from the air. Excessmoisture can cause corrosion and a dangerous loss of braking effectiveness. 23When adding fluid, it is a good idea to inspect the reservoir for contamination. The system should be drained and refilled if deposits, dirt particles or contamination are seen in the fluid. 24After filling the reservoir to the correct level, make sure that the cap is refitted securely, to avoid leaks and the entry of foreign matter. 25If the reservoir requires repeated replenishing to maintain the correct level, this is an indication of an hydraulic leak somewhere in the system, which should be investigated immediately. Power steering fluid 26See Section 5 of this Chapter. 1Periodic inspection of the tyres may spare you from the inconvenience of being stranded with a flat tyre. It can also provide you with vital information regarding possible problems in the steering and suspension systems before major damage occurs. 2The original tyres on this vehicle are equipped with tread wear indicator (TWI) bands, which will appear when the tread depth reaches approximately 1.6 mm. Most tyres have a mark around the tyre at regular intervals to indicate the location of the tread 4 Tyre and tyre pressure checks 1•8 3.17 Topping-up the windscreen washer reservoir3.18 On non-sealed batteries, keep the electrolyte level of all the cells in the battery between the maximum and minimum levels (arrowed) - ie, 10 mm above the plates.

wear indicators, the mark being TWI, an arrow, or the tyre manufacturer’s symbol (see illustration). Tread wear can also be monitored with a simple inexpensive device known as a tread depth indicator gauge (see illustration). 3Ensure that tyre pressures are checked regularly and maintained correctly (see the Specifications at the beginning of this Chapterfor pressures). Checking should be carried out with the tyres cold, and notimmediately after the vehicle has been in use. If the pressures are checked with the tyres hot, an apparently- high reading will be obtained, owing to heat expansion. Under no circumstancesshould an attempt be made to reduce the pressures to the quoted cold reading in this instance, or effective under-inflation will result. 1•9 1 Tyre Tread Wear Patterns Shoulder Wear Underinflation (wear on both sides) Check and adjust pressures Incorrect wheel camber (wear on one side) Repair or renew suspension parts Hard cornering Reduce speed! Centre Wear Overinflation Check and adjust pressures If you sometimes have to inflate your car’s tyres to the higher pressures specified for maximum load or sustained high speed, don’t forget to reduce the pres- sures to normal afterwards.

It therefore pays to carry a good-quality tyre pressure gauge in the vehicle, to make the regular checks required and ensure pressure accuracy. 4Note any abnormal tread wear (see illustration). Tread pattern irregularities such as feathering, flat spots, and more wear on one side than the other, are indications of front wheel alignment and/or balance problems. If any of these conditions are noted, they should be rectified as soon as possible.5Under-inflation will cause overheating of the tyre, owing to excessive flexing of the casing, and the tread will not sit correctly on the road surface. This will cause a consequent loss of adhesion and excessive wear, not to mention the danger of sudden tyre failure due to heat build-up. 6Over-inflation will cause rapid wear of thecentre part of the tyre tread, coupled with reduced adhesion, harder ride, and the danger of damage occurring in the tyre casing. 7Regularly check the tyres for damage in the form of cuts or bulges, especially in the sidewalls. Remove any nails or stones embedded in the tread, before they penetrate
the tyre to cause deflation. If removal of a nail reveals that the tyre has been punctured, refit the nail, so that its point of penetration is marked. Then immediately change the wheel, and have the tyre repaired by a tyre dealer. Do not drive on a tyre in such a condition. If in any doubt as to the possible consequences of any damage found, consult your local tyre dealer for advice. 8General tyre wear is influenced to a large degree by driving style - harsh braking and acceleration, or fast cornering, will all produce more rapid tyre wear. Interchanging of tyres may result in more even wear; however, it is worth bearing in mind that if this is completely effective, the added expense is incurred of replacing simultaneously a complete set of tyres, which may prove financially restrictive for many owners. 9Front tyres may wear unevenly as a result of wheel misalignment. The front wheels should always be correctly aligned according to the settings specified by the vehicle manufacturer.10Don’t forget to check the spare tyre for condition and pressure. 11Legal restrictions apply to many aspects of tyre fitting and usage, and in the UK this information is contained in the Motor Vehicle Construction and Use Regulations. It is suggested that a copy of these regulations is obtained from your local police, if in doubt as to current legal requirements with regard to tyre type and condition, minimum tread depth, etc. 1The power steering fluid reservoir is located on the right-hand rear corner of the engine compartment. 2For the fluid level check, the power steering system should be at its normal operating temperature, so it is best to carry out the check after a run. 3Position the vehicle on level ground, withthe front wheels pointing straight ahead, and switch off the engine. 4Check that the fluid level is up to the “MAX” mark on the reservoir (see illustration). 5If topping-up is required, first use a clean rag to wipe the filler cap and the surrounding area, to prevent foreign matter from entering the system. Unscrew and remove the filler cap. 6Top-up the level to the “MAX” mark, using the grade of fluid specified at the beginning of this Chapter (see illustration). Be careful not to introduce dirt into the system, and do not overfill. The need for frequent topping-up indicates a leak, which should be investigated. 7Refit the filler cap. 1The windscreen wiper and blade assembly should be inspected at the specified intervals for damage, loose components, and cracked or worn blade elements. 2Road film can build up on the wiper blades and affect their efficiency, so they should be washed regularly with a mild detergent solution. 3The action of the wiping mechanism can loosen bolts, nuts and fasteners, so they should be checked and tightened, as necessary, at the same time as the wiper blades are checked. 4If the wiper blade elements are cracked, worn or warped, or no longer clean adequately, they should be replaced with new ones. 5Lift the wiper arm and blade away from the glass. 6To remove the windscreen wiper blade, release the catch on the arm, then turn the blade through 90° and withdraw the blade from the end of the arm (see illustration). 7To remove the tailgate wiper blade, push the wiper blade forward, and at the same time depress it against the spring pressure, then withdraw it from the end of the arm (see illustration). 8If the metal part of the wiper blade is in good condition, it may be possible to renew the rubber insert separately. The insert can be obtained from a car accessory shop and, according to type, it may need to be cut to the correct length before sliding into the clips. 9Refit the wiper blade assembly using a reversal of the removal procedure, making sure that it fully engages with the spring clip. 10Check that the washer jets direct the fluid onto the upper part of the windscreen/tailgate/rear window/headlight, and if necessary adjust the small sphere on the jet with a pin. 6 Windscreen/tailgate washer system and wiper blade check 5 Power steering fluid level check 1•10 5.4 Power steering fluid reservoir, showing “MAX” and “MIN” marks5.6 Topping-up the power steering fluid reservoir 6.7 Tailgate wiper blade removal6.6 Releasing the catch to remove a windscreen wiper blade Weekly checks
Every 10 000 miles or 12 months 1•11 17.4 Removing the automatic transmission dipstick from its tube7.6A “MIN” and “MAX” marks on the dipstick7.6B Adding automatic transmission fluid through the dipstick tube Every 10 000 miles 1The level of the automatic transmission fluid should be carefully maintained. Low fluid level can lead to slipping or loss of drive, while overfilling can cause foaming, loss of fluid and transmission damage. 2The transmission fluid level should only be checked when the transmission is hot (at its normal operating temperature). If the vehicle has just been driven over 10 miles (15 miles in a cold climate), and the fluid temperature is 160 to 175°F, the transmission is hot. Caution: If the vehicle has just been driven for a long time at high speed or in city traffic in hot weather, or if it has been pulling a trailer, an accurate fluid level reading cannot be obtained. In these circumstances, allow the fluid to cool down for about 30 minutes. 3Park the vehicle on level ground, apply the handbrake, and start the engine. While the engine is idling, depress the brake pedal and move the selector lever through all the gear ranges three times, beginning and ending in “P”. 4Allow the engine to idle for one minute, then (with the engine still idling) remove the dipstick from its tube (see illustration). Note the condition and colour of the fluid on the dipstick. 5Wipe the fluid from the dipstick with a clean rag, and re-insert it into the filler tube until the cap seats. 6Pull the dipstick out again, and note the fluid level. The level should be between the “MIN” and “MAX” marks. If the level is on the “MIN” mark, stop the engine, and add the specified automatic transmission fluid through the dipstick tube, using a clean funnel if necessary (see illustrations). It is important not to introduce dirt into the transmission when topping-up. 7Add the fluid a little at a time, and keep checking the level as previously described until it is correct.8The need for regular topping-up of the transmission fluid indicates a leak, which should be found and rectified without delay. 9The condition of the fluid should also be checked along with the level. If the fluid at the end of the dipstick is black or a dark reddish- brown colour, or if it has a burned smell, the fluid should be changed. If you are in doubt about the condition of the fluid, purchase some new fluid, and compare the two for colour and smell. 1Check the operation of all external lights and indicators (front and rear). 2Check for satisfactory operation of the instrument panel, its illumination and warning lights, the switches and their function lights. 3Check the horn(s) for satisfactory operation. 4Check all other electrical equipment for satisfactory operation. 5Check all electrical wiring in the engine compartment for correct routing, and for any signs of physical or heat-damage or chafing. Warning: Certain precautions must be followed when checking and servicing the battery. Hydrogen gas, which is highly flammable, is always present in the battery cells, so keep lighted tobacco and all other open flames and sparks away from the battery. The electrolyte inside the battery is actually dilute sulphuric acid, which will cause injury if splashed on your skin or in your eyes. It will also ruin clothes and painted surfaces. When disconnecting the battery, always detach the negative (earth) lead first and connect it last! Note: Before disconnecting the battery, refer to Section 1 of Chapter 5. 9 Battery check, maintenance and charging 8 Electrical system check 7 Automatic transmission fluid level check 9.1 Tools and materials required for battery maintenance 1Face shield/safety goggles- When removing corrosion with a brush, the acidic particles can easily fly up into your eyes 2Baking soda- A solution of baking soda and water can be used to neutralise corrosion 3Petroleum jelly- A layer of this on the battery terminals will help prevent corrosion 4Battery terminal/lead cleaner- This wire brush cleaning tool will remove all traces of corrosion from the battery terminals and lead clamps 5Treated felt washers- Placing one of these on each terminal, directly under the lead clamps, will help prevent corrosion 6Puller- Sometimes the lead clamps are very difficult to pull off the terminals, even after the nut has been completely slackened.

General 1A routine preventive maintenance programme for the battery in your vehicle is the only way to ensure quick and reliable starts. Before performing any battery maintenance, make sure that you have the proper equipment necessary to work safely around the battery (see illustration). 2There are also several precautions that should be taken whenever battery maintenance is performed. Before servicing the battery, always turn the engine and all accessories off, and disconnect the lead from the negative terminal of the battery - see Chapter 5, Section 1. 3The battery produces hydrogen gas, which is both flammable and explosive. Never create a spark, smoke, or light a match around the battery. Always charge the battery in a well- ventilated area. 4Electrolyte contains poisonous and corrosive sulphuric acid. Do not allow it to get in your eyes, on your skin, or on your clothes. Never ingest it. Wear protective safety glasses when working near the battery. Keep children away from the battery. 5Note the external condition of the battery. If the positive terminal and lead clamp on your vehicle’s battery is equipped with a plastic cover or rubber protector, make sure that it’s not torn or damaged. It should completelycover the terminal. Look for any corroded or loose connections, cracks in the case or cover, or loose hold-down clamps. Also check the entire length of each lead for cracks and frayed conductors. 6If corrosion, which looks like white, fluffy deposits (see illustration)is evident, particularly around the terminals, the battery should be removed for cleaning. Slacken the lead clamp nuts with a spanner, being careful to remove the negative (earth) lead first, and slide them off the terminals (see illustration). Then unscrew the hold-down clamp nuts, remove the clamp, and lift the battery from the engine compartment. 7Clean the lead clamps thoroughly, using a soft wire brush or a terminal cleaner, with a solution of warm water and baking soda. Wash the terminals and the top of the battery case with the same solution, but make sure that the solution doesn’t get into the battery. When cleaning the leads, terminals and battery top, wear safety goggles and rubber gloves, to prevent any solution from coming in contact with your eyes or hands. Wear old clothes too - even when diluted, sulphuric acid splashed onto clothes will burn holes in them. If the terminals have been extensively corroded, clean them up with a terminal cleaner (see illustrations). Thoroughly wash all cleaned areas with plain water. 8Make sure that the battery tray is in good condition and the hold-down clamp nuts are tight (see illustration). If the battery isremoved from the tray, make sure no parts remain in the bottom of the tray when the battery is refitted. When refitting the hold-down clamp nuts, do not overtighten them. 9Information on removing and installing the battery can be found in Chapter 5. Information on jump starting can be found at the front of this manual. For more detailed battery checking procedures, refer to the Haynes Automobile Electrical and Electronic Systems Manual. Cleaning 10Corrosion on the hold-down components, battery case and surrounding areas can be removed with a solution of water and baking soda. Thoroughly rinse all cleaned areas with plain water. 11Any metal parts of the vehicle damaged by corrosion should be covered with a zinc-based primer, then painted. Charging Warning: When batteries are being charged, hydrogen gas, which is very explosive and flammable, is produced. Do not smoke, or allow open flames, near a charging or a recently-charged battery. Wear eye protection when near the battery during charging. Also, make sure the charger is unplugged before connecting or disconnecting the battery from the charger. 12Slow-rate charging is the best way to restore a battery that’s discharged to the point where it will not start the engine. It’s also a good way to maintain the battery charge in a vehicle that’s only driven a few miles between starts. Maintaining the battery charge is particularly important in winter, when the battery must work harder to start the engine, and electrical accessories that drain the battery are in greater use. 13It’s best to use a one- or two-amp battery charger (sometimes called a “trickle” charger). They are the safest, and put the least strain on the battery. They are also the least expensive. For a faster charge, you can use a higher- 1•12 9.6A Battery terminal corrosion usually appears as light, fluffy powder9.6B Removing a lead from the battery terminal - always remove the earth lead first, and connect it last!9.7A When cleaning the lead clamps, all corrosion must be removed - the inside of the clamp is tapered to match the terminal, so don’t remove too much material 9.7B Regardless of the method used to clean the terminals, a clean, shiny surface should result9.8 Make sure the battery hold-down nuts (arrowed) are tight Every 10 000 miles
amperage charger, but don’t use one rated more than 1/10th the amp/hour rating of the battery (ie no more than 5 amps, typically). Rapid boost charges that claim to restore the power of the battery in one to two hours are hardest on the battery, and can damage batteries not in good condition. This type of charging should only be used in emergency situations. 14The average time necessary to charge a battery should be listed in the instructions that come with the charger. As a general rule, a trickle charger will charge a battery in 12 to 16 hours. 1Check the seat belts for satisfactory operation and condition. Inspect the webbing for fraying and cuts. Check that they retract smoothly and without binding into their reels. 2Check that the seat belt mounting bolts are tight, and if necessary tighten them to the specified torque wrench setting. General 1The auxiliary drivebelt is of the flat, multi- ribbed (or “polyvee”) type, and is located on the right-hand end of the engine. It drives the alternator, water pump, power steering pump and (when fitted) the air conditioning compressor from the engine’s crankshaft pulley. 2The good condition and proper tension of the auxiliary drivebelt is critical to the operation of the engine. Because of their composition and the high stresses to which they are subjected, drivebelts stretch anddeteriorate as they get older. They must, therefore, be regularly inspected. Check 3With the engine switched off, open and support the bonnet, then locate the auxiliary drivebelt on the right-hand end of the engine, under the engine right-hand mounting bracket. (Be very careful, and wear protective gloves to minimise the risk of burning your hands on hot components, if the engine has recently been running.) For improved access, jack up the front right-hand side of the vehicle, support it securely on an axle stand, remove the roadwheel, then remove the auxiliary drivebelt cover (two fasteners) from inside the wheel arch (see illustration). 4Using an inspection light or a small electric torch, and rotating the engine when necessary with a spanner applied to the crankshaft pulley bolt, check the whole length of the drivebelt for cracks, separation of the rubber, and torn or worn ribs (see illustration). Also check for fraying and glazing, which gives the drivebelt a shiny appearance. Both sides of the drivebelt should be inspected, which means you will have to twist the drivebelt to check the underside. Use your fingers to feel the drivebelt where you can’t see it. If you are in any doubt as to the condition of the drivebelt, renew it (go to paragraph 7). Drivebelt tension 5The auxiliary drivebelt is tensioned by an automatic tensioner; regular checks are not required, and manual “adjustment” is not possible. 6If you suspect that the drivebelt is slipping and/or running slack, or that the tensioner is otherwise faulty, it must be renewed. To do this, remove the drivebelt as described below, then unbolt the tensioner (two Torx-type screws accessible from underneath, via the wheel arch) from the alternator mounting bracket (see illustration). On fitting the new tensioner, ensure it is aligned correctly on its mountings, and tighten the screws to the specified torque wrench setting. Renewal 7Open the bonnet. Jack up the front right- hand side of the vehicle and support it securely on an axle stand, remove the roadwheel, then remove the auxiliary drivebelt cover (two fasteners) from inside the wheel arch. 8If the existing drivebelt is to be refitted, mark it, or note the maker’s markings on its flat surface, so that it can be installed the same way round. 9Reaching up between the body and the engine (above and to the rear of the crankshaft pulley), apply a spanner to the hexagon in the centre of the automatic tensioner’s pulley. Rotate the tensioner pulley clockwise to release its pressure on the drivebelt, then slip the drivebelt off the crankshaft pulley, and release the tensioner again (see illustration). Working from the wheel arch or engine compartment as necessary, and noting its routing, slip the drivebelt off the remaining pulleys and withdraw it. 10Check all the pulleys, ensuring that their grooves are clean, and removing all traces of oil and grease. Check that the tensioner works properly, with strong spring pressure 11 Auxiliary drivebelt check and renewal 10 Seat belt check 1•13 1 11.9 Rotate the tensioner pulley clockwise to release its pressure on the drivebelt, then slip the drivebelt off the crankshaft pulley 11.3 Removing the auxiliary drivebelt cover - it is secured by a fastener at each end (arrowed) - from inside the right-hand front wheel arch 11.4 Check the auxiliary drivebelt for signs of wear like these. Very small cracks across the drivebelt ribs are acceptable.

being felt when its pulley is rotated clockwise, and a smooth return to the limit of its travel when released. 11If the original drivebelt is being refitted, use the marks or notes made on removal, to ensure that it is installed to run in the same direction as it was previously. To fit the drivebelt, arrange it on the grooved pulleys so that it is centred in their grooves, and not overlapping their raised sides (note that the flat surface of the drivebelt is engaged on the idler, tensioner and water pump pulleys) and routed correctly (see illustrations). Start at the top, and work down to finish at the crankshaft pulley; rotate the tensioner pulley clockwise, slip the drivebelt onto the crankshaft pulley, then release the tensioner again. 12Using a spanner applied to the crankshaft pulley bolt, rotate the crankshaft through at least two full turns clockwise to settle the drivebelt on the pulleys, then check that the drivebelt is properly installed. 13Refit the auxiliary drivebelt cover and roadwheel, then lower the vehicle to the ground. Caution: Renewal of air conditioning hoses must be left to a dealer service department or air conditioning specialist who has the equipment to depressurise the systemsafely. Never remove air conditioning components or hoses until the system has been depressurised. General 1High temperatures in the engine compartment can cause the deterioration of the rubber and plastic hoses used for engine, accessory and emission systems operation. Periodic inspection should be made for cracks, loose clamps, material hardening and leaks. 2Carefully check the large top and bottom radiator hoses, along with the other smaller- diameter cooling system hoses and metal pipes; do not forget the heater hoses/pipes which run from the engine to the bulkhead, and those to the engine oil cooler (where fitted). Inspect each hose along its entire length, replacing any that is cracked, swollen or shows signs of deterioration. Cracks may become more apparent if the hose is squeezed (see illustration). If you are using non-Ford specification antifreeze, and so have to renew the coolant every two years or so, it’s a good idea to renew the hoses at that time, regardless of their apparent condition. 3Make sure that all hose connections are tight. A leak in the cooling system will usually show up as white- or rust-coloured deposits on the areas adjoining the leak; if the spring clamps that are used to secure the hoses in this system appear to be slackening, they should be renewed to prevent the possibility of leaks. 4Some other hoses are secured to theirfittings with clamps. Where clamps are used, check to be sure they haven’t lost their tension, allowing the hose to leak. If clamps aren’t used, make sure the hose has not expanded and/or hardened where it slips over the fitting, allowing it to leak. 12 Underbonnet check for fluid leaks and hose condition 1•14 11.11A When installing the auxiliary drivebelt, make sure that it is centred - it must not overlap either edge of the grooved pulleys11.11B Auxiliary drivebelt routing 1 Power steering pump 2 Idler pulley 3 Alternator4 Automatic tensioner 5 Air conditioning compressor (when fitted)6 Crankshaft pulley 7 Water pump pulley 12.2 Hoses, like drivebelts, have a habit of failing at the worst possible time - to prevent the inconvenience of a blown radiator or heater hose, inspect them carefully as shown here Every 10 000 miles
5Check all fluid reservoirs, filler caps, drain plugs and fittings etc, looking for any signs of leakage of oil, transmission and/or brake hydraulic fluid, coolant and power steering fluid. If the vehicle is regularly parked in the same place, close inspection of the ground underneath it will soon show any leaks; ignore the puddle of water which will be left if the air conditioning system is in use. As soon as a leak is detected, its source must be traced and rectified. Where oil has been leaking for some time, it is usually necessary to use a steam cleaner, pressure washer or similar, to clean away the accumulated dirt, so that the exact source of the leak can be identified. Vacuum hoses 6It’s quite common for vacuum hoses, especially those in the emissions system, to be colour-coded, or to be identified by coloured stripes moulded into them. Various systems require hoses with different wall thicknesses, collapse resistance and temperature resistance. When renewing hoses, be sure the new ones are made of the same material. 7Often the only effective way to check a hose is to remove it completely from the vehicle. If more than one hose is removed, be sure to label the hoses and fittings to ensure correct installation. 8When checking vacuum hoses, be sure to include any plastic T-fittings in the check. Inspect the fittings for cracks, and check the hose where it fits over the fitting for distortion, which could cause leakage. 9A small piece of vacuum hose (quarter-inch inside diameter) can be used as a stethoscope to detect vacuum leaks. Hold one end of the hose to your ear, and probe around vacuum hoses and fittings, listening for the “hissing” sound characteristic of a vacuum leak. Warning: When probing with the vacuum hose stethoscope, be very careful not to come into contact with moving engine components such as the auxiliary drivebelt, radiator electric cooling fan, etc. Fuel hoses Warning: There are certain precautions which must be taken when inspecting or servicing fuel system components. Work in a well- ventilated area, and do not allow open flames (cigarettes, appliance pilot lights, etc.) or bare light bulbs near the work area. Mop up any spills immediately, and do not store fuel-soaked rags where they could ignite. 10Check all fuel hoses for deterioration and chafing. Check especially for cracks in areas where the hose bends, and also just before fittings, such as where a hose attaches to the fuel filter. 11High-quality fuel line, usually identified by the word “Fluoroelastomer” printed on thehose, should be used for fuel line renewal. Never, under any circumstances, use unreinforced vacuum line, clear plastic tubing or water hose for fuel lines. 12Spring-type clamps are commonly used on fuel lines. These clamps often lose their tension over a period of time, and can be “sprung” during removal. Replace all spring-type clamps with screw clamps whenever a hose is replaced. Metal lines 13Sections of metal piping are often used for fuel line between the fuel filter and the engine. Check carefully to be sure the piping has not been bent or crimped, and that cracks have not started in the line. 14If a section of metal fuel line must be renewed, only seamless steel piping should be used, since copper and aluminium piping don’t have the strength necessary to withstand normal engine vibration. 15Check the metal brake lines where they enter the master cylinder and ABS hydraulic unit (if used) for cracks in the lines or loose fittings. Any sign of brake fluid leakage calls for an immediate and thorough inspection of the brake system. 1With the vehicle parked on level ground, apply the handbrake firmly and open the bonnet. Using an inspection light or a small electric torch, check all visible wiring within and beneath the engine compartment. 2What you are looking for is wiring that is obviously damaged by chafing against sharp edges, or against moving suspension/ transmission components and/or the auxiliary drivebelt, by being trapped or crushed between carelessly-refitted components, or melted by being forced into contact with the hot engine castings, coolant pipes, etc. In almost all cases, damage of this sort is caused in the first instance by incorrect routing on reassembly after previous work has been carried out. 3Depending on the extent of the problem, damaged wiring may be repaired by rejoining the break or splicing-in a new length of wire, using solder to ensure a good connection, and remaking the insulation with adhesive insulating tape or heat-shrink tubing, as appropriate. If the damage is extensive, given the implications for the vehicle’s future reliability, the best long-term answer may well be to renew that entire section of the loom, however expensive this may appear. 4When the actual damage has been repaired, ensure that the wiring loom is re- routed correctly, so that it is clear of other components, and not stretched or kinked, and is secured out of harm’s way using the plastic clips, guides and ties provided. 5Check all electrical connectors, ensuringthat they are clean, securely fastened, and that each is locked by its plastic tabs or wire clip, as appropriate. If any connector shows external signs of corrosion (accumulations of white or green deposits, or streaks of “rust”), or if any is thought to be dirty, it must be unplugged and cleaned using electrical contact cleaner. If the connector pins are severely corroded, the connector must be renewed; note that this may mean the renewal of that entire section of the loom - see your local Ford dealer for details. 6If the cleaner completely removes the corrosion to leave the connector in a satisfactory condition, it would be wise to pack the connector with a suitable material which will exclude dirt and moisture, preventing the corrosion from occurring again; a Ford dealer may be able to recommend a suitable product. 7Check the condition of the battery connections - remake the connections or renew the leads if a fault is found (see Chap- ter 5). Use the same techniques to ensure that all earth points in the engine compartment provide good electrical contact through clean, metal-to-metal joints, and that all are securely fastened. (In addition to the earth connection at the engine lifting eye, and that from the transmission to the body/battery, there are one or two earth points behind each headlight assembly, and one below the power steering fluid reservoir.) 8Refer to Section 31 for details of spark plug (HT) lead checks. Warning: The air conditioning system is under high pressure. Do not loosen any fittings or remove any components until after the system has been discharged. Air conditioning refrigerant must be properly discharged into an approved type of container, at a dealer service department or an automotive air conditioning repair facility capable of handling R134a refrigerant. Always wear eye protection when disconnecting air conditioning system fittings. 1The following maintenance checks should be performed on a regular basis, to ensure that the air conditioner continues to operate at peak efficiency: (a) Check the auxiliary drivebelt. If it’s worn or deteriorated, renew it (see Section 11). (b) Check the system hoses. Look for cracks, bubbles, hard spots and deterioration. Inspect the hoses and all fittings for oil bubbles and seepage. If there’s any evidence of wear, damage or leaks, renew the hose(s). (c) Inspect the condenser fins for leaves, insects and other debris. Use a “fin 14 Air conditioning system check 13 Engine compartment wiring check 1•15 1 Every 10 000 miles
comb” or compressed air to clean the condenser. Warning: Wear eye protection when using compressed air! (d) Check that the drain tube from the front of the evaporator is clear - note that it is normal to have clear fluid (water) dripping from this while the system is in operation, to the extent that quite a large puddle can be left under the vehicle when it is parked. 2It’s a good idea to operate the system forabout 30 minutes at least once a month, particularly during the winter. Long term non-use can cause hardening, and subsequent failure, of the seals. 3Because of the complexity of the air conditioning system and the special equipment necessary to service it, in-depth fault diagnosis and repairs are not included in this manual. For more complete information on the air conditioning system, refer to the Haynes Automotive Heating and Air Conditioning Manual. 4The most common cause of poor cooling is simply a low system refrigerant charge. If a noticeable drop in cool air output occurs, the following quick check will help you determine if the refrigerant level is low. 5Warm the engine up to normal operating temperature. 6Place the air conditioning temperature selector at the coldest setting, and put the blower at the highest setting. Open the doors - to make sure the air conditioning system doesn’t cycle off as soon as it cools the passenger compartment. 7With the compressor engaged - the clutch will make an audible click, and the centre of the clutch will rotate - feel the inlet and outlet pipes at the compressor. One side should be cold, and one hot. If there’s no perceptible difference between the two pipes, there’s something wrong with the compressor or the system. It might be a low charge - it might be something else. Take the vehicle to a dealer service department or an automotive air conditioning specialist.1Make sure that you have all the necessary tools before you begin this procedure (see illustration). You should also have plenty of rags or newspapers handy, for mopping up any spills. 2To avoid any possibility of scalding, and to protect yourself from possible skin irritants and other harmful contaminants in used engine oils, it is advisable to wear gloves when carrying out this work. 3Access to the underside of the vehicle is greatly improved if the vehicle can be lifted on a hoist, driven onto ramps, or supported by axle stands. Warning: Do not work under a vehicle which is supported only by an hydraulic or scissors-type jack, or by bricks, blocks of wood, etc. 4If this is your first oil change, get under the vehicle and familiarise yourself with the position of the engine oil drain plug, which is located at the rear of the sump. The engine and exhaust components will be warm during the actual work, so try to anticipate any potential problems while the engine and accessories are cool. 5The oil should preferably be changed when the engine is still fully warmed-up to normal operating temperature, just after a run (the needle on the temperature gauge should be in the “Normal” sector of the gauge); warm oil and sludge will flow out more easily. Park the vehicle on firm, level ground, apply the handbrake firmly, then select 1st or reverse gear (manual transmission) or the “P” position (automatic transmission). Open the bonnet and remove the engine oil filler cap from the cylinder head cover, then remove the oil level dipstick from its tube (see Section 3). 6Raise the front of the vehicle, and support it securely on axle stands. Remove the front right-hand roadwheel to provide access to the oil filter; if the additional working clearance is required, remove also the auxiliary drivebelt cover (two fasteners). 15 Engine oil and filter change 1•16 15.1 These tools are required when changing the engine oil and filter 1Drain pan- It should be fairly shallow in depth, but wide to prevent spills 2Rubber gloves- When removing the drain plug and filter, it is inevitable that you will get oil on your hands (the gloves will prevent burns from hot oil) 3Breaker bar- Sometimes the oil drain plug is pretty tight, and a long breaker bar is needed to loosen it 4Socket- To be used with the breaker bar or a ratchet (must be the correct size to fit the drain plug) 5Filter wrench- This is a metal band-type wrench, which requires clearance around the filter to be effective 6Filter wrench- This type fits on the bottom of the filter, and can be turned with a ratchet or breaker bar (different size wrenches are available for different types of filters) 15.7 Use the correct-size spanner or socket to remove the oil drain plug and avoid rounding it off15.9 Since the oil filter is usually on very tight, you’ll need a special wrench for removal. DO NOT use the wrench to tighten the new filter. Pack rag under the filter before removal to minimise the mess Every 10 000 miles Frequent oil changes are the best preventive maintenance the home mechanic can give the engine, because ageing oil becomes diluted and contaminated, which leads to premature engine wear.
