²5.0L engine
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge will be near the
center of the NORMAL band).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir.
5.If your vehicle is equipped with a 4.0L EFI engine,the fluid level
should be in the FULL HOT range. Do not add fluid if the level is in this
range.
6.If your vehicle is equipped with a 4.0L SOHC engine or a 5.0L
engine,the fluid level should be between the MIN and MAX lines. Do
not add fluid if the level is in this range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the correct operating range. Be sure to put the
cap back on the reservoir.
TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ``Service Guide''.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in theLubricant specificationssection in theCapacities and
specificationschapter.

An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not drive the vehicle if the fluid
level is below the bottom hole on
the dipstick and outside
temperatures are above 10ÉC (50ÉF)
(see figure to the right).
Your transmission does not use up fluid. However, it is recommended
that you check the transmission fluid at least twice a year. The fluid level
should be checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid should be checked at normal operating temperatures
66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal operating
temperature can be reached after approximately 32 km (20 miles) of
driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]) (see figure to the
right).
The transmission fluid should be in
this range if at room temperature
(10ÉC-35ÉC [50ÉF-95ÉF]) (see figure
to the right).
If your vehicle has been operated for an extended period at high speeds,
in city traffic during hot weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow the fluid to cool before
checking.
1. Park the vehicle on a level surface and engage the parking brake.

2. With the parking brake engaged
and your foot on the brake pedal,
start the engine and move the
gearshift lever through all of the
gear ranges. Allow sufficient time
for each gear to engage.
3. Latch the gearshift lever in P
(Park) and leave the engine running.
4. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
5. Install the dipstick making sure it is fully seated in the filler tube.
6. Remove the dipstick and inspect the fluid level. The fluid level should
be within the top hole area on the dipstick.
7. If necessary, add fluid in 250ml (1/2 pint) increments through the filler
tube until the level is correct.
8. If an overfill occurs, excess fluid should be removed by a qualified
technician.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
If the fluid level is above the
crosshatch (hot operating range)
area after driving the vehicle for
approximately 30 km (20 miles),
excess transmission fluid should be
removed by a qualified technician.

Checking and adding manual transmission fluid
1. Clean the filler plug.
2. Remove the filler plug and
inspect the fluid level.
3. Fluid level should be at bottom of
the opening.
4. Add enough fluid through the
filler opening so that the fluid level
is at the bottom of the opening.
5. Install and tighten the fill plug.
Use only fluid that meets Ford specifications. Refer to theCapacities
and specificationschapter.

Use only fluid that meets Ford specifications. Refer to theCapacities

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
The universal joints standard with your vehicle do not require
lubrication. If the original universal joints are replaced with universal
joints equipped with grease fittings, lubrication will be necessary.
BATTERY
Your vehicle may be equipped with a
Superstart maintenance-free battery.
If the original equipment battery
needs replacing, it may be replaced
with a low-maintenance battery. The
low-maintenance battery normally
does not require additional water
during its life of service. However,
for severe usage or in high
temperature climates, check your
battery electrolyte level, at least
every 24 months or 40,000 km
(24,000 miles). Keep the electrolyte
in each cell up to the ``level'' indicator. Do not overfill the battery cells.
If the electrolyte level in the battery is low, you can add plain tap water
to the battery, as long as you do not use hard water (water with a high
alkali content). If possible, however, try to only fill the battery cells with
distilled water. If the battery needs water often, have the charging
system checked.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminal(s) and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water. Reinstall the cables when
you are done cleaning them, and apply a small quantity of grease to the
top of each battery terminal to help prevent corrosion.
If your battery has a cover/shield, make sure it is reinstalled
after the battery is replaced.
Because your vehicle's engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must

relearn its idle conditions before your vehicle will drive properly. To
begin this process:
1. Put the gearshift in P (Park) (automatic transmissions) or the neutral
position (manual transmissions), turn off all accessories and start the
vehicle.
2. Let the engine idle for at least one minute.
3. The relearning process will automatically complete as you drive the
vehicle.
²If you do not allow the engine to relearn its idle, the idle quality of
your vehicle may be adversely affected until the idle is eventually
relearned.
²If the battery has been disconnected or a new battery has been
installed, the clock and the preset radio stations must be reset once
the battery is reconnected.
²Always dispose of automotive
batteries in a responsible manner.
Follow your community's
standards for disposal. Call your
local recycling center to find out
more about recycling automotive
batteries.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Changing the wiper blades
When replacing wiper blade assemblies, always use a Motorcraft part or
equivalent. To make replacing the wipers easy, turn the ignition to ACC,
then turn the wipers on. When the wipers reach the vertical position,
turn the ignition to LOCK.
