1999 FORD EXPLORER engine coolant

If the engine coolant has not been checked at the 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.
Do not mix conventional green coolant, orange coolant or
recycled coolants together in your vehicle. Use only the type of
coolant that your vehicle was originally equipped with. If you are
unsure which type of coolant your vehicle requires, contact your
local dealer.
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 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 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.
Maintenance and care
211

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.
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.
Maintenance and care
212

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.
Maintenance and care
213

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.If your vehicle is equipped with a 4.0L OHV V6 engine,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 your vehicle is equipped with a 4.0L SOHC V6 or a 5.0L V8
engine,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.
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
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 warmed up
(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.

2Fill to 6 mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
3Vehicles equipped with 4.0L OHV V6 and 4.0L SOHC V6 engines may
be equipped with a conventional rear axle. Refer to your Scheduled
Maintenance Guide for axle fluid change intervals.
4Vehicles equipped with 4.0L OHV V6 and 4.0L SOHC V6 engines 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.
