10. If necessary, add a50/50 mixtureof engine
coolant and distilled water to the engine coolant
reservoir until the coolant level is at the ªcold fill
levelº as listed on the reservoir.
After any coolant has been added, check the coolant
concentration see Checking Engine Coolant section).
If the concentration is not 50/50 (protection to
±34ÉF/±36ÉC), drain some coolant and adjust the
concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level in
the coolant reservoir should be checked the next few
times you drive the vehicle. If necessary, add enough
50/50 concentration of engine coolant and distilled
water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of
engine coolant per month, have your dealer check
the engine cooling system. Your cooling system may
have a leak. Operating an engine with a low level of
coolant can result in engine overheating and possible
engine damage.
Recycled engine coolant
Ford Motor Company recommends the use of a
recycled engine coolant produced by Ford-approved
processes in vehicles originally equipped with
Motorcraft Premium Engine Coolant (green-colored).
However, not all coolant recycling processes produce
coolant that meets Ford specification
ESE-M97B44±A. Use of such coolant may harm the
engine and cooling system components.
Ford Motor Company does NOT recommend the use
of recycled engine coolant in vehicles originally
equipped with Motorcraft Premium Gold Engine
Coolant since a Ford-approved recycling process is
not yet available.
Used engine coolant should be disposed of in
an appropriate manner. Follow your community's
regulations and standards for recycling and disposing
of automotive fluids.

Coolant refill capacity
To find out how much fluid your vehicle's cooling
system can hold, refer toRefill capacitiesin the
Capacities and specificationschapter.
Fill your engine coolant reservoir as outlined in
Adding engine coolantin this chapter.
Severe climates
If you drive in extremely cold climates (less than
±36É C [±34É F]):
²it may be necessary to increase the coolant
concentration above 50%.
²NEVER increase the coolant concentration
above 60%.
²increased engine coolant concentrations
above 60% will decrease the overheat
protection characteristics of the engine
coolant and may cause engine damage.
²refer to the chart on the coolant container
to ensure the coolant concentration in your
vehicle will provide adequate freeze
protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
²it is still necessary to maintain the coolant
concentration above 40%.
²NEVER decrease the coolant concentration
below 40%.
²decreased engine coolant concentrations
below 40% will decrease the corrosion
protection characteristics of the engine
coolant and may cause engine damage.
²decreased engine coolant concentrations
below 40% will decrease the freeze
protection characteristics of the engine
coolant and may cause engine damage.
Maintenance and care
165

²refer to the chart on the coolant container
to ensure the coolant concentration in your
vehicle will provide adequate protection at
the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates
should use a 50/50 mixture of engine coolant and
distilled water for optimum cooling system and
engine protection.
CHECKING AND ADDING POWER STEERING
FLUID
Check the power steering fluid. Refer to the
scheduled maintenance guide for the service interval
schedules. If adding fluid is necessary, use only
MERCONtAT F.
If your vehicle is
equipped with the
3.8L V6 engine,check
the power steering
fluid level with the
engine at normal
operating temperature.
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 on the dipstick. It should be
within the FULL HOT range. 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.
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
(if equipped)
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.MAXMIN
Maintenance and care

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
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 30 km (20 miles) 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 compartmentin 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 10ÉC
(50ÉF).
Correct fluid level
The transmission fluid should be checked at normal
operating temperature 66ÉC-77ÉC (150ÉF-170ÉF) on
Maintenance and care
168

a level surface. The normal operating temperature
can be reached after approximately 30 km (20
miles) of driving.
You can check the fluid without driving if the
ambient temperature is above 10ÉC (50ÉF). 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 (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 also in theLubricant
specificationssection in theCapacities 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.
Maintenance and care
169

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.
Checking and adding manual transmission fluid
(if equipped)
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 securely.
Use only fluid that meets Ford specifications. Refer
to theCapacities and specificationschapter.
