2009 DODGE GRAND CARAVAN engine overheat

FREEING A STUCK VEHICLEIf your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then move the shift lever back and forth
between REVERSE and DRIVE. Using minimal accelera-
tor pedal pressure to maintain the rocking motion, with-
out spinning the wheels, is most effective.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
35 mph (55 km/h) when you are stuck. Do not let
anyone near a spinning wheel, no matter what the
speed. CAUTION!
Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 35 mph (55 km/h).
TOWING A DISABLED VEHICLE
Towing With The Ignition Key
Your vehicle may be towed under the following condi-
tions:
The shift lever must be in NEUTRAL.
The distance to be traveled must not exceed 100 miles
(160 km).
The towing speed must not exceed 44 mph (72 km/h).
WHAT TO DO IN EMERGENCIES 427
6

CAUTION!Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you. WARNING!A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut OFF and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer’s specifications, should be ob-
tained immediately.
444 MAINTAINING YOUR VEHICLE

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent the loss of
engine coolant (antifreeze), and to ensure that engine
coolant (antifreeze) will return to the radiator from the
coolant recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces. WARNING!

The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
when the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine. Heat
causes pressure to build up in the cooling system.
To prevent scalding or injury, do not remove the
pressure cap while the system is hot or under
pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal of Used Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
