2000 FORD MUSTANG cooling

Operating tips
²In humid weather, selectbefore driving.
This will reduce fogging on your windshield. After
a few minutes, select any desired position.
²To reduce humidity buildup inside the vehicle,
don't drive with the climate control system in the
OFF or MAX A/C position.
²Don't put objects under the front seat that will
interfere with the airflow to the back seats.
²Remove any snow,
ice or leaves from
the air intake area
(at the bottom of
the windshield).
²If your vehicle has been parked with the windows
closed during hot weather, the air conditioner will
do a much faster job of cooling if you drive for
two or three minutes with the windows open. This
will force most of the hot, stale air out of the
vehicle. Then operate your air conditioner as you
would normally.
²Do not place objects over the defroster outlets.
These objects can block airflow and reduce your
ability to see through your windshield. Also, avoid
placing small objects on top of your instrument
panel. These objects can fall down into the
defroster outlets and block airflow and possibly
damage your climate control system.
Do not place objects on top of the
instrument panel, as these objects may
become projectiles in a collision or sudden stop.

adjusted to the manufacturer's specifications. The
trailer brakes must meet local and Federal
regulations.
Do not connect a trailer's hydraulic brake
system directly to your vehicle's brake
system. Your vehicle may not have enough braking
power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for
operation at the GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles.
Make sure your trailer lamps conform to local and
Federal regulations. See your dealer or trailer rental
agency for proper instructions and equipment for
hooking up trailer lamps.
Driving while you tow
When towing a trailer:
²Ensure that you turn off your speed control. The
speed control may shut off automatically when
you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations
for towing a trailer.
²Use a lower gear when towing up or down steep
hills. This will eliminate excessive downshifting
and upshifting for optimum fuel economy and
transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal
transmission damage and void your warranty
coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
Driving
113

your Scheduled Maintenance guide for more
information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.
Recreational towing (all wheels on the ground)
Follow these guidelines for your specific powertrain
combination to tow your vehicle with all four wheels
on the ground (such as behind a recreational
vehicle).
These guidelines are designed to ensure that your
transmission is not damaged due to insufficient
lubrication.
All Rear Wheel Drive (RWD) vehicles
This applies to all cars and 4x2 trucks/sport utilities
with rear wheel drive capability.
An example of recreational towing is towing your
vehicle behind a Motorhome. The following
recreational towing guidelines are designed to

2. Place the lug nut wrench over the lug nut key and
apply pressure on the key with the wrench.
3. Install the lug nut.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes.
An explosion could result in injury or vehicle
damage.
Do not push start your vehicle. You could
damage the catalytic converter.
Batteries contain sulfuric acid which can
burn skin, eyes, and clothing, if contacted.
Do not attempt to push start your vehicle.
Automatic transmissions do not have
push-start capability.
Preparing your vehicle
1.Use only a 12±volt supply to start your
vehicle.
2. Do not disconnect the battery of the disabled
vehicle as this could damage the vehicle's electrical
system.
3. Park the booster vehicle close to the hood of the
disabled vehicle making sure the two vehiclesdo
nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other
moving parts.
4. Check all battery terminals and remove any
excessive corrosion before you attach the battery
cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect
any electrical surges. Turn all other accessories off.

WINDSHIELD WASHER FLUID
Checking and adding 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
specifications. Refer toLubricant specificationsin
theCapacities and specificationschapter.
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.
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 COOLANT
Checking engine coolant
Your engine's cooling system has been factory-filled
with a 50/50 mixture of distilled water and Ford
Premium Engine Coolant E2FZ-19549-AA (in
Canada, Motorcraft CXC-10), or an equivalent
premium engine coolant that meets Ford
specification ESE-M97B44-A.
Maintenance and care

A50/50 mixtureof distilled water and Ford
Premium Engine Coolantprovides:
²maximum cooling system efficiency.
²freeze protection down to -36É C (-34É F).
²boiling protection up to 129É C (265É F).
²protection against rust and other forms of
corrosion.
²an accurate temperature readout from the
engine coolant gauge.
The engine coolant must be maintained at the
correct fluid level and concentration to work
properly. If the engine coolant fluid level and
concentration is not maintained correctly,
damage to the engine and cooling system may
result.

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.
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
Use only Ford Premium Engine Coolant
E2FZ-19549-AA (in Canada, Motorcraft
CXC-8-B) or a premium engine coolant that
meets Ford specification ESE-M97B44-A.
²DO NOT USE Ford Extended Life Engine
Coolant F6AZ-19544-AA (orange in color).
²DO NOT USE a DEX-COOLtengine coolant
or an equivalent engine coolant that meets
Ford specification WSS-M97B44-D.
²DO NOT USE alcohol or methanol antifreeze
or any engine coolants mixed with alcohol or
methanol antifreeze.
²DO NOT USE supplemental coolant additives
in your vehicle. These additives may harm
your engine's cooling system.
