²If the oil level is below the MIN
mark, add enough oil to raise the
level within the MIN-MAX range.
²Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the MIN and MAX ranges, add only
certified engine oil of the recommended viscosity. Remove the engine oil
filler cap and use a funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the dipstick.
Engine oil and filter recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Maintenance and care
111

Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the ªService Guideº.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and
refilled as needed at least once each
year:
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
Maintenance and care
112

2. Visually inspect the fluid level.
3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.
WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is on
the right side of the engine
compartment and is highlighted with
a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Do not put engine coolant in the container for the windshield
washer fluid.

ENGINE COOLANT
Check the level of the engine
coolant in the reservoir at least once
a month. Be sure to read and
understandPrecautions when
servicing your vehiclein this
chapter.
If the engine coolant has not been checked at the above recommended
interval, the engine coolant reservoir may become empty. If this occurs,
add engine coolant to the reservoir. For more information on engine
coolant maintenance, refer toAdding engine coolantin this chapter.
Automotive fluids are not interchangeable; do not use engine coolant,
antifreeze or windshield washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
Do not put engine coolant in the container for the windshield
washer fluid.
If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.
When the engine is cool, add a 50/50 mixture of engine coolant and
water to the engine coolant recovery reservoir-DO NOT ADD DIRECTLY
TO THE RADIATOR. Add straight water only in an emergency, but you
should replace it with a 50/50 mixture of coolant and distilled water as
soon as possible.
Check the coolant level in the coolant recovery reservoir the next few
times you drive the vehicle. If necessary, add enough of a 50/50 mixture
of coolant and water to bring the liquid level to the fill line on the
reservoir.
Never remove the coolant recovery cap while the engine is
running or hot.
Maintenance and care
114

If you must remove the coolant recovery 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.
Use Ford Premium Cooling System Fluid E2FZ-19549±AA (in Canada,
Motorcraft CXC-8±B) or an equivalent premium engine coolant that
meets Ford specification ESE-M97B44±A. Ford Premium Engine Coolant
is an optimized formula that will protect all metals and rubber elastomers
used in Ford cooling systems for four years or 80,000 km (50,000 miles).
Do not use alcohol or methanol antifreeze or any engine coolants mixed
with alcohol or methanol antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm your engine cooling
system. The use of an improper coolant may void your warranty of your
vehicle's engine cooling system.
Recycled engine coolant
Ford Motor Company recommends that Ford and Lincoln-Mercury
dealers use recycled engine coolant produced by Ford-approved
processes. Not all coolant recycling processes produce coolant which
meets Ford specification ESE-M97B44±A, and use of such coolant 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.
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.
Maintenance and care
115

Severe winter climate
If you drive in extremely cold climates (less than ±36ÉC [±34ÉF]), it may
be necessary to increase the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the coolant concentration in
your vehicle is such that the coolant will not freeze at the temperature
level in which you drive during winter months. Never increase the engine
coolant concentration above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in non-extreme climates.
How fail-safe cooling works
²Standard cluster
²Optional cluster
If the engine overheats, the engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs:
²if your vehicle is equipped with analog gauges, the engine coolant
temperature gauge will move to the H (hot) area

²if your vehicle is equipped with digital gauges, the engine coolant
temperature gauge will illuminate all eight bars and a tone will sound
every five seconds for a minute
²the
symbol will illuminate
²theCheck Engineindicator light will illuminate.
The vehicle will still operate, however:
²the engine power will be limited
²the air conditioning system will be disabled
Continued operation will increase the engine temperature:
²the
symbol will begin to flash
²if your vehicle is equipped with digital gauges, the gauge bars will
flash and a tone will sound continuously for thirty seconds
²the engine will completely shut down
²steering and braking effort will increase
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant recovery cap while the engine is
running or hot.
5. Re-start the engine and take your vehicle to a service facility.
Maintenance and care
117

Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid at
least twice a year. If adding fluid is
necessary, use only MERCONtAT 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.

TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ªService Guide.º
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.
