If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. 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 within this range.
5. 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 automatic transmission fluid
Refer to your Scheduled Maintenance Guide for
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 30 km [20 miles]). If your vehicle has
MAXMIN
Maintenance and care

could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66ÉC-77ÉC [150ÉF-170ÉF]).
The transmission fluid
should be in this range
if at ambient
temperature (10ÉC-35ÉC [50ÉF-95ÉF]).
High fluid level
Fluid levels above the
safe range may result
in transmission failure.
An overfill condition of transmission fluid may cause
shift and/or engagement concerns and/or possible
damage.
High fluid levels can be caused by an overheating
condition.
Adjusting automatic transmission fluid levels
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 the
Capacities and specificationschapter.
Use of a non-approved automatic transmission
fluid may cause internal transmission
component damage.
If necessary, add fluid in 250 mL (1/2 pint)
increments through the filler tube until the level is
correct.
If an overfill occurs,
excess fluid should be
removed by a qualified
technician.

Premium Cooling System Fluid. If your coolant is
orange in color, use Ford Extended Life Engine
Coolant. Refer toAdding engine coolant, in the
Maintenance and Care chapter.
2Rear axle 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. Fill 6 mm to 14 mm
(1/4 inch to 9/16 inch) below bottom of fill hole. Add
118 ml (4 oz.) of additive friction modifier
C8AZ-19B546-A, Ford specification EST-M2C118±A for
complete refill of Traction-Lok axles.
3Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
