1999 Mercury Mountaineer engine coolant

Check the coolant level in the coolant 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 reservoir cap while the engine is
running or hot.
If you must remove the coolant reservoir 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.
Change your engine coolant according to the appropriate schedule listed
in the Scheduled Maintenance Guide.
Before adding engine coolant, check the color of the coolant in your
vehicle.
For vehicles with green coolant,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.
Do not add orange coolant or recycled coolant to your vehicle
originally equipped with conventional green coolant.
For vehicles with orange coolant,use Ford Extended Life Engine
Coolant F6AZ-19544±AA or a DEX-COOLtequivalent that meets Ford
specification WSS-M97B44±D.
Do not add conventional green coolant or recycled coolant to
your vehicle originally equipped with orange coolant.
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.
Maintenance and care

Recycled engine coolant
Ford Motor Company recommends that Ford and Lincoln-Mercury
dealers use recycled engine coolant produced by Ford-approved
processes.
For vehicles with green coolant,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.
For vehicles with orange coolant,no recycling process has been
approved at this time 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.
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.
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.

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.
7. 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.

1If your engine coolant is green in color, use Ford 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.
2Fill to 6 mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
3Vehicles equipped with a 4.0L SOHC V6 engine may be equipped with a
conventional rear axle. Refer to your Scheduled Maintenance Guide for
axle fluid change intervals.
4Vehicles equipped with 4.0L SOHC V6 engine and 3.73:1 or 4.10:1 rear
axle ratios or with a 5.0L V8 engine require synthetic rear axle lubricant.
Rear axles containing synthetic lubricant are lubricated for life. These
lubricants are not to be checked or changed unless a leak is suspected or
service is required. The axle lubricant should be changed any time the
axle has been submerged in water.
Add 118 ml (4 oz.) of additive friction modifier C8AZ-19B546-A, Ford
specification EST-M2C118±A for complete refill of Traction-Lok axles.
