2002 FORD MUSTANG coolant reservoir

Never remove the coolant reservoir cap
while the engine is running or hot. Steam
and scalding liquid from a hot cooling system can
burn you badly.
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.
Engine oil pressure gauge
Indicates engine oil
pressure. At normal
operating temperature,
the needle will be in
the normal range (the area between the ªLº and
ªHº); if the needle goes below the normal range,
stop the vehicle as soon as safely possible and
switch off the engine immediately. Check the oil
level. Add oil if needed (refer toEngine oilin the
Maintenance and specificationschapter). If the oil
level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Battery voltage gauge
Indicates battery
voltage. If the pointer
moves and stays
outside the normal
operating range (as indicated by the arrows), have
the vehicle's electrical system checked as soon as
possible.

WINDSHIELD WASHER FLUID
Washer fluid
Check the washer fluid
whenever you stop for
fuel. The reservoir 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.
Only use a washer fluid that meets Ford
specification ESR-M17P5±A. Refer toLubricant
specificationsin this chapter.
State or local regulations on volatile organic
compounds may restrict the use of methanol, a
common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze
agents should be used only if they provide cold
weather protection without damaging the vehicle's
paint finish, wiper blades or washer system.
Note:Do not put washer fluid in the engine coolant
reservoir. Washer fluid placed in the cooling system
may harm engine and cooling system components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the
appropriate intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 5 to 10 minutes for
the oil to drain into the oil pan.
3. Set the parking brake and ensure the gearshift is
securely latched in P (Park) (automatic
transmissions) or 1 (First) (manual transmissions).

²Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
recycling center to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36É C (-34É F).
Coolant concentration testing is possible with a
hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014±R1060).
The level of coolant should be maintained at the
ªcold fullº of ªcold fill rangeº level in the coolant
reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine
coolant and water concentration. If the
concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not
work properly.A 50±50 mixture of coolant and
water provides the following:
²freeze protection down to -36É C (-34É F)
²boiling protection up to 129É C (265É F)
²protection against rust and other forms of
corrosion
²enables calibrated gages to function properly

When the engine is cold, check the level of the
engine coolant in the reservoir.
²The engine coolant should be at the ªcold fill
levelº as listed on the engine coolant reservoir.
²Refer to the scheduled maintenance guide for
service interval schedules.
²Be sure to read and understandPrecautions
when servicing your vehiclein this chapter.
If the engine coolant has not been checked at the
recommended interval, the engine coolant reservoir
may become low or empty. If the reservoir is low or
empty, add engine coolant to the reservoir. Refer to
Adding engine coolantin this chapter.

washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50
mixture of engine coolant and distilled water. Add
the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is
obtained.
Do not add engine coolant when the engine
is hot. Steam and scalding liquids released
from a hot cooling system can burn you badly.
Also, you can be burned if you spill coolant on hot
engine parts.
Do not put engine coolant in the windshield
washer fluid container. If sprayed on the
windshield, engine coolant could make it difficult
to see through the windshield.
The cooling system in your vehicle is filled with
either green-colored Motorcraft Premium Engine
Coolant meeting Ford specification ESE-M97B44±A
or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification
WSS-M97B51±A1. To determine your vehicle's
coolant type (color), check your coolant reservoir.
²Add Motorcraft Premium Engine Coolant
(green-colored), VC-4±A (U.S.) or CXC-10
(Canada) or Motorcraft Premium Gold
Engine Coolant (yellow-colored), VC-7±A,
depending on the type of coolant originally
equipped in your vehicle.
If you are unsure
which type of coolant your vehicle requires, check
your coolant reservoir or contact your local dealer.
Note:Use of Motorcraft Cooling System Stop Leak
Pellets, VC-6, darkens the color of Motorcraft Premium
Gold Engine Coolant from yellow to golden tan.

If you must remove the pressure relief cap or
radiator cap (depending upon engine application),
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.
Engine coolant refill procedure-3.8L V6 engine
Note:Use the following procedure when refilling the
cooling system of a vehicle equipped with a 3.8L V6
engine. Failure to follow this warning may result in
damage to the engine and engine cooling system.
The following procedure should be used when
refilling the cooling system of a 3.8L V6 engine after
it has been drained or become extremely low.
1. Remove the cap
from the engine
coolant reservoir.
2. Open the cooling
system vent plug.
3. Remove the radiator
cap as previously
outlined.
4. Add a50/50 mixtureof engine coolant and
distilled water to the radiator until full.
5. Add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir until
the coolant level is at the ªcold fill levelº as listed on
the reservoir.
6. Close the cooling system vent plug.
7. Reinstall the engine coolant reservoir cap.
