1999 Mercury Mountaineer coolant temperature

High beams
Illuminates when the high beam
headlamps are turned on.
Anti-theft system (if equipped)
Refer toSecuriLockypassive
anti-theft systemin theControls
and featureschapter.
Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Check gage
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position. Refer toEngine coolant temperature gauge, Engine oil
pressure gaugeorFuel gaugein this chapter for more information.
Four wheel drive low (if equipped)
This light momentarily illuminates
when the ignition is turned to ON.
Illuminates when four-wheel drive
low is engaged. If the light continues
to flash have the system serviced.

Speedometer
Indicates the current vehicle speed.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.

STARTING THE ENGINE
1. Turn the key to 5 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return to
4 (ON).
2. If the temperature is above ±12ÉC (10ÉF) and the engine does not
start within five seconds on the first try, turn the key to OFF, wait ten
seconds and try again.
3. If the temperature is below -12ÉC (10ÉF) and the engine does not
start in fifteen seconds on the first try, turn the key OFF and wait ten
seconds and try again. If the engine does not start in two attempts,
depress the accelerator and start the engine while holding the
accelerator down to the floor. Release the accelerator when the engine
starts.
4. After idling for a few seconds, apply the brake and release the parking
brake.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23ÉC
(-10ÉF) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.

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.
Maintenance and care

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.
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.
