NOTICE:
If your engine catches fire because
you keep driving with
no coolant,
your vehicle can be badly damaged.
The costly repairs would not be
covered by your warranty.
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 gel
a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
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
window as necessary.
3. Tr!
to keep your engine under load
(in a drive gear where the engine runs
slower).
[f 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.
[f 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.
Cooling System
When you decide it’s safe to lift the hood,
here’s what you’ll see on the
V6 engine:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fan

Downloaded from www.Manualslib.com manuals search engine On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
A CAUTION:
An electric fan under the hood can
start up even when the engine is not
running and can injure
you. Keep
hands, clothing and tools
away from
any underhood electric fan.
II
If the coolant inside the coolant recovery
tank is boiling, don’t do anything else
until it cools down.
When
it is cool, remove the coolant
recovery tank cap and look at
the dipstick.
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.
A CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Don’t
touch them. If you do, you can be
burned.
Don’t
run the engine if there is a
leak. If you run the engine, it could
lose all coolant. That could
cause an
engine fire, and you could be burned.
Get any leak fixed before you drive
the vehicle.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty. I
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.

1. You can remove the radiator pressure
cap when the cooling system,
including
the radiator pressure cap ant
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.
4. Then fill the coolant recovery tank to
“FULL COLD.”
5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap
off.

you can feel the upper radiator hose
getting hot. Watch out for the engine
fan(s).
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 any
time during this procedure if coolant
begins to
flow out of the filler neck,
reinstall the pressure cap. Be sure the
arrows on the pressure cap line up
like
this.

To Check Coolant:
When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level
should be at
“COLD,” or a little higher.
When your engine
is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.
If you have the 5.7L LTI (Code P) engine
and this light comes on,
it means you’re
low on engine coolant.
To Add Coolant to the Recovery Tank:
If you need more coolant, add the proper
mix at the coolant recovery tank, but only
when your engine
is cool. If the tank is
very low or empty, also add coolant to the
radiator, see “Engine Overheating” in the
Index for information.

e CAUTION:
Turning the radiator pressure cap when the engine and radiator
are hot
can allow steam and scalding liquids
to
blow out and burn you badly.
Never
turn the pressure cap - even a
little
- when the engine and radiator
are hot.
Add coolant mix at the recovery tank, bul
be careful not to spill
it.
A CAUTION:
You can be burned if you spill
coolant on hot engine parts. Coolant
contains ethylene glycol,
and it will
bum if the engine parts are hot
enough. Don't spill coolant
on a
hot engine.
Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi
(1 24 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, an
AC@ 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.

Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look
at the fluid level on
the dipstick.
