To drain the cooling system, open the radiator petcock (arrow) and allow the coolant to drain
into a container
HOW TO USE THIS BOOK
DRAINING, FLUSHING & REFILLING 137 

A length of hose (A) can be fitted to the petcock (B) to help direct the flow of the coolant and
avoid spills

Drain the existing antifreeze and coolant. Open the radiator and engine drains (petcocks) or
disconnect the bottom radiator hose at the radiator outlet. The engine block drain plugs can also be
temporarily removed to drain coolant, but they are often hard to get at and it is not really necessary for
this procedure.
1. 
Close the petcock or reconnect the hose (and install any...

Close all petcocks and connect any loose hoses.
7. 
If equipped with a coolant recovery system, flush the reservoir with water and leave empty.
8. 
To refill the system with coolant, remove the radiator cap. NEVER remove the cap if the system is HOT
Use a funnel to avoid spills and fill the radiator with a 50/50 mixture of water/antifreeze
Determine the capacity of the coolant system, then properly refill the cooling system with a 50/50
mixture of fresh coolant and water, as follows: Fill the radiator...

The system should be pressure checked whenever leakage is suspected and cant be seen
CAUTION
If you are checking for leaks with the system at normal operating temperature, BE EXTREMELY CAREFUL
not to touch any moving or hot engine parts. Once the temperature has been reached, shut the engine OFF, and
check for leaks around the hose fittings and connections which were removed earlier.
Check the level of protection with an antifreeze/coolant hydrometer.

Brake Master Cylinder
FLUID RECOMMENDATIONS...

The brake master cylinder fluid level should be maintained at the MAX mark on the reservoir
The master cylinder reservoir is located under the hood, on the left side firewall. All vehicles covered by this
manual should be equipped with a see-through plastic reservoir. This makes checking the level easy and helps
reduce the risk of fluid contamination (since you dont have to expose the fluid by opening the cap to check
the level). Fluid should be kept near the FULL line or between the MIN and MAX lines,...

If it becomes necessary to add fluid to the system, take a moment to clean the area around the cap and
reservoir. Use a clean rag to wipe away dust and dirt which could enter the reservoir after the cover is
removed. If the level of the brake fluid is less than half the volume of the reservoir (and the brake pads are not
approaching a replacement point), it is advised that you check the brake system for leaks. Leaks in the
hydraulic system often occur at the wheel cylinders.
Clutch Master Cylinder
FLUID...

1996-99 Models
The 1996-99 models utilize Mercon® Automatic Transmission Fluid (ATF). Ensure that the fluid added to
the power steering pump reservoir is new and clean.
LEVEL CHECK
The level of the power steering fluid should be checked in the reservoir periodically, at least once a year.
Fluid is checked using the dipstick which is attached to the reservoir cap. Although the dipstick is equipped
with range markings so that you can check the fluid hot or cold, it is recommended that you check the fluid...

The level should read between the MAX and MIN marks on the dipstick (HOT marks on
opposite side)
Add the proper amount and type of fluid to attain a FULL (MAX) reading on the dipstick
If the level is below the indicator markings, add fluid to bring it up to the proper level (a funnel is
usually very helpful). If you are checking the level after running the engine or driving, make sure you
add enough fluid to bring it to the FULL HOT range, but like most automotive fluids, DO NOT
overfill.
4. 
When you...

Wipe the grease fittings clean before greasing in order to prevent the possibility of forcing any dirt into the
component.
There are far less grease points on the modern automotive chassis than there were on trucks of yesteryear. The
tie rod ends on these vehicles should be checked and lubricated periodically, and the front suspension should
be checked for grease fittings.
A water resistant long life grease that meets Fords ESA-M1C75-B specification should be used for all
chassis greasing applications....

This procedure only covers the repacking (or greasing) of the wheel bearings. For the removal
procedures see the appropriate Section for you vehicle. For 4 wheel drive vehicles, see Section 7. For 2
wheel drive vehicles, see Section 8.
