If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly damaged.

If No Steam Is Coming From your
Engine
If you get the overheat warning but see
or hear no steam, the problem may not
be too serious. Sometimes the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
If you get the overheat warning with no
sign
of steam, try this for a minute or so:
1. If you have an air conditioner, turn it
2. Turn on your heater to full hot at the
Off.
highest fan speed and open the
windows as necessary.
3.
Try to keep your engine under load
(in
a drive gear where the engine
runs slower).
If you no longer have the overheat
warning, you can drive. Just
to be safe,
drive slower for about ten minutes.
If
the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over,
stop, and park your vehicle right away.
If there’s still no sign
of steam, you can
idle the engine for two or three minutes
while you’re parked, to see if the
warning stops. But then, if you still
have the warning, TURN
OFF THE
ENGINE AND
GET EVERYONE OUT
OF THE VEHICLE until it cools down.
You may decide not
to lift the hood but
to get service help right away.

The coolant level should be at or above
FULL COLD. If it isn’t, you may have
a leak in the radiator hoses, heater
hoses, radiator, water pump or
somewhere else in the cooling system.

NOTICE:
Engine damage from running your
engine without coolant isn’t
covered by your warranty.
If there seems to be no leak, check to
see if the electric engine fan is running.
If the engine is overheating, the fan
should be running. If it isn’t, your
vehicle needs service.

How to Add Coolant to the 2.21
14 Engne at the Radiator
1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to
the left until
it first stops. (Don’t
press down while turning the
pressure cap.) If you hear a hiss, wait
for that to stop. A hiss means there is
still some pressure left.

2. Then keep turning the pressure cap,
but now push down as you turn it.
Remove the pressure cap. 3. Fill the radiator with the proper mix,
up to the base of the filler neck.

5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap off. 6. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fan.
7. By this time the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more
of the
proper
mix through the filler neck
until the level reaches the base of the
filler neck.

8. Then replace the pressure cap. At anj
time during this procedure
if coolant
begins to flow
out of the filler neck,
reinstall the pressure cap. Be sure the
arrows
on pressure cap line up like

How to Add Coolant to the 3.7L V6
€ngine at the Coolant Surge Tank
If you haven't found a problem yet, but
the coolant level isn't at or above the
FULL COLD mark, add a 50/50 mixture
of clean water (preferably distilled) and
a proper antifreeze at the coolant surge
tank, but be sure the cooling system,
including the coolant surge tank pressure
cap,
is cool before you do it. (See CooZuni
in the Index for more information about
the proper coolant mix.)
NOTICE:
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts.
So use
the recommended coolant.

Ifa Tire Goes Flat
It’s unusual for a tire to “blow out”
while you’re driving, especially
if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a
blowout^" here are a few tips
about what to expect and what
to do:

Adding Coolant -3. IL V6 Engine
To Check Coolant
When your engine is cold, the coolant
level should be at
FULL COLD, or a

higher.
To Add Coolant
If you need more coolant, add the

mix at the surge tank.

Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105
kPa) pressure-type cap and must be
tightly installed to prevent coolant
loss and possible engine damage
from overheating. Be sure the arrows
on the cap line up with the overflow
tube on the radiator filler neck.
When
you replace your radiator
pressure cap, a
GM cap is recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the radiator
until the coolant reaches a preset
temperature.
When
you replace your thermostat, an
AC@ thermostat is recommended.
