Adding engine coolant
Use only Ford Premium Engine Coolant E2FZ-19549-AA (in
Canada, Motorcraft CXC-10) or a premium engine coolant that
meets Ford specification ESE-M97B44-A. Use only Ford G05
Engine Coolant WSSÐM97B51±A1 (in Canada, Motorcraft
CXC-10) or a premium engine coolant that meets Ford
specification ESE-M97B44-A.
²DO NOT USE Ford Extended Life Engine Coolant
F6AZ-19544-AA (orange in color).
²DO NOT USE a DEX-COOLtengine coolant or an equivalent
engine coolant that meets Ford specification WSS-M97B44-D.
²DO NOT USE alcohol or methanol antifreeze or any engine
coolants mixed with alcohol or methanol antifreeze.
²DO NOT USE supplemental coolant additives in your vehicle.
These additives may harm your engine's cooling system.
²DO NOT MIX recycled coolant and conventional coolant
together in your vehicle. Mixing of engine coolants may harm
your engine's cooling system.
²The use of an improper coolant may harm engine and cooling
system components and may void the warranty of your vehicle's
engine cooling system. If you are unsure which type of coolant
your vehicle requires, contact your local dealer.
Do not put engine coolant in the windshield washer fluid
reservoir. If engine coolant is sprayed onto the windshield, it
could make it difficult to see through the windshield.
When the engine is cool, add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir, until the coolant is at the
ªcold fill levelº or within the ªcold fill rangeº as listed in the engine
coolant reservoir (depending upon application).
²NEVER increase the coolant concentration above 60%.
²NEVER decrease the coolant concentration below 40%.
²Engine coolant concentrations above 60% or below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
Maintenance and care

Plain water may be added in an emergency, but youmustreplace it with
a 50/50 mixture of engine coolant and distilled water as soon as possible.
Check the coolant level in the reservoir before you drive your vehicle the
next few times (with the engine cool). 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 or within the
ªcold fill rangeº as listed on the reservoir (depending upon application).
Have your dealer check the engine cooling system for leaks if you have
to add more than 1.0 liter (1.0 quart) of engine coolant per month.
To avoid scalding hot steam or coolant from being released from
the engine cooling system, never remove the reservoir cap while
the engine is running or hot. Failure to follow this warning may result
in damage to the engine's cooling system and possible severe personal
injury.
If you must remove the coolant cap, follow these steps to avoid personal
injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Recycled engine coolant
Ford Motor Company recommends the use of a recycled engine coolant
produced by Ford-approved processes.
Not all coolant recycling processes produce coolant which meets Ford
specification WSS-M97B51±A1. Use of a recycled engine coolant which
does not meet the Ford G05 specification may harm engine and cooling
system components.
Always dispose of used automotive fluids in a responsible 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 theCapacities and specificationschapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in 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.
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.
²4.0L SOHC V6 engine
²5.0L V8 engine
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.
5. The fluid level should be between the MIN and MAX lines. Do not add
fluid if the level is in this range.

6. 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.
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 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.
Maintenance and care
213

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 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 the
Lubricant specificationssection in theCapacities and specifications
chapter.
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.
An overfill condition of
transmission fluid may cause
shift and/or engagement
concerns and/or possible
damage.

CHECKING AND ADDING TRANSFER CASE FLUID (IF EQUIPPED)
1. Clean the filler plug.
2. Remove the filler plug and
inspect the fluid level.
3. Add only enough fluid through
the filler opening so that the fluid
level is at the bottom of the
opening.
Use only fluid that meets Ford specifications. Refer to theCapacities
and specificationschapter.
DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to the scheduled maintenance guide for maintenance
intervals. If the original universal joints are replaced with universal joints
equipped with grease fittings, lubrication will also be necessary.
