POWER STEERING FLUID
Check the power steering fluid.
Refer toscheduled maintenance
for the service interval schedules.If
adding fluid is necessary, use
only MERCONAT F.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
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. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.

1. Clean the reservoir cap before
removal to prevent dirt and water
from entering the reservoir.
2. Remove cap and rubber
diaphragm from reservoir.
3. Add fluid until the level reaches
the step in the reservoir.
4. Reinstall rubber diaphragm and
cap onto reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, 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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 km]). 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 fluid to cool before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. 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.

4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated area for normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the ambient temperature is
above 50°F (10°C).
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 150°F-170°F (66°C-77°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
You can check the fluid without driving if the ambient temperature is
above 50°F (10°C). However, if fluid is added at this time, an overfill
condition could result when the vehicle reaches normal operating
temperature.
The transmission fluid should be in
this range if at normal operating
temperature (150°F-170°F
[66°C-77°C]).
The transmission fluid should be in
this range if at ambient temperature
(50°F-95°F [10°C-35°C]).

AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft part numbersin this chapter.
Note:Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.
Changing the air filter element
•4.2L/4.6L engines
1. Loosen the clamp that secures
the air filter element in place.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the open end of the air filter
housing.
4. Install a new air filter element.
5. Reassemble the two halves of the air filter housing, aligning the notch
and slot found on the top of each half. Secure the clamp, making sure
not to crimp the air filter edges between the two halves of the air filter
housing. This could cause filter damage and allow unmetered air to enter
the engine if not properly seated.

•5.4L Engine
1. Release two retainer clamps.
2. Pull air filter tray assembly out
toward front of vehicle and lift air
filter element up and out of housing.
The air filter box needs to be free of any debris before installing a new
air filter.
3. Install a new air filter element
into the tray assembly.
4. Return air filter tray to original
position by pressing firmly on the
handle until all rearward movement
stops and secure the two clamps.

5Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and
is considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
6Service refill capacity is determined by filling the axle to 1/4-9/16 inch
(6-14 mm) below the bottom of the filler hole with the vehicle on a level
surface.
Add 4 oz. (118 ml) of Additive Friction Modifier XL–3 or equivalent
meeting Ford specification EST-M2C118–A, for complete fill of 8.8 inch
and 9.75 inch Traction-Lok axles.
7Service refill capacity is determined by filling the axle to the bottom of
the filler hole with the vehicle on a level surface.
For 10.25 inch Traction-Lok axles, use 6.5 pints (3.1L) of Motorcraft SAE
75W-140 Synthetic Rear Axle Lubricant and 8 oz. (236 ml) of Additive
Friction Modifier XL–3 or equivalent meeting Ford Specification
EST-M2C118-A.
8Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C930-A and the API Certification mark.
