overheating FORD THUNDERBIRD 2002 11.G Owners Manual

Turn signal chime
Sounds when the turn signal lever has been activated to signal a turn and
not turned off after the vehicle is driven more than 0.8 km (1/2 mile).
GAUGES
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 the
needle goes above the normal range,
the engine is overheating. Stop the
vehicle as soon as safely possible,
switch off the engine immediately
and let the engine cool. Refer to
Engine coolantin the
Maintenance and specificationschapter.
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.

controlling wheel spin. The system borrows many of the electronic and
mechanical elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels ªsearchº for optimum traction several times a second and
adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads. This is especially evident if wheel spin-up should occur
while turning.
During Traction Controlyoperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
ªrev-upº when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow
or on a very slippery road surface,
try switching the Traction Controly
system off using the traction control
switch located on the left-hand side
of the instrument panel. This may
allow excess wheel spin to ªdigº the
vehicle out or enable a successful
ªrockingº maneuver.
If the Traction Controlysystem is
cycled excessively, the brake portion
of the system will shut down to prevent the rear brakes from
overheating. A limited Traction Controlyfunction using only engine
torque reduction will still help control wheels from over-spinning. When
the rear brakes have cooled down, the system will again function
normally. Anti-lock braking is not affected by this condition and will
function normally during the cool down period.

engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
²Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
²Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
²Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the ªcold fullº level. For all other vehicles, which have a coolant
degas system with a pressurized cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator of a vehicle with an overflow
system, follow these steps to add engine coolant.
To avoid personal injury, make sure the engine is cool before
unscrewing the coolant pressure relief cap. The cooling system is
under pressure; steam and hot liquid can come out forcefully when the
cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) 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.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the ªcold fill rangeº or the ªcold fullº level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)

After any coolant has been added, check the coolant concentration see
Checking Engine Coolant section). If the concentration is not 50/50
(protection to ±34É F/±36É C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Recycled engine coolant
Ford Motor Company recommends the use of a recycled engine coolant
produced by Ford-approved processes in vehicles originally equipped
with Motorcraft Premium Engine Coolant (green-colored). However, not
all coolant recycling processes produce coolant that meets Ford
specification ESE-M97B44±A. Use of such coolant may harm the engine
and cooling system components.
Ford Motor Company does NOT recommend the use of recycled engine
coolant in vehicles originally equipped with Motorcraft Premium Gold
Engine Coolant since a Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
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 this chapter.
