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.
Tow a trailer. If you get
the overheat warning with no
sign of steam,
try this for a minute or so:
1 . Turn off your air conditioner.
2. Turn on your heater to full hot at the
highest fan speed and open the
window 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.
Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan, or fans if you
have the rear climate control system
or the
3800 V6 engine.
I A An electric fan under the hod
L 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.
If the coolant inside the coolant
recovery
tank is boiling, don’t do
anything else
until it cools down.

Adding only plain water to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water or the
wrong
mix, your engine could get
too hot but
you wouldn’t get the
overheat warning. Your engine
could catch fire and you or others
could be burned. Use a
50/50 mix
of clean water and a proper
antifreeze.

You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn
if the engine parts
are hot enough. Don’t spill coolant
on a hot engine.
I
When the coolant in the coolant
recovery
tank is at or above the FULL
HOT mark, start your vehicle.
If the overheat warning continues,
there’s one more thing you can try. You
can add the proper coolant
mix directly
to the radiator, but be sure the cooling
system is cool before
you do it.

Problems on the Road
Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should
be
60 psi (420 Pa). The compact spare is
made to go up to
3,000 miles (5 000 km),
so you can finish your trip and have
your full-size tire repaired or replaced
where you want.
Of course, it’s best to
replace your spare with a full-size tire as
soon as you can. Your spare will last
longer and be
in good shape in case you
need it again.
Your anti-lock brake system warning
light may come on when you are driving
with a compact spare. See the
Index
under Anti-Lock Brake System Warning
Light.
Don’t use your compact spare on some

through an automatic car wash
with guide rails. The compact
spare can get caught on the rails.
That can damage the tire and
wheel, and maybe other parts
of
your vehicle. And don’t
mix your compact
spare or
wheel with other wheels
or tires. They
won’t fit. Keep your spare
and its wheel
together.

NOTICE
If you use an improper coolant
mix, your engine could overheat
and be badly damaged. The repail
cost wouldn’t
be covered by your
warranty. Too much water

Adding Coolant
To Check Coolant:
When your engine is cold, the coolant
level should be
at COLD, or a little
higher. When
your engine is warm, the
level should be
up to mJLL HOT, or a
little higher.

If you have too much brake
fluid, it can spill on the
engine. The fluid will burn if the
engine is hot enough. You OT
others could be burned, and your
vehicle could be damaged. Add
brake fluid only when work is
done on the brake hydraulic
system.
When your brake fluid falls to a low
level, your brake warning light will
come on. See the
Index under Brake
System Warning Light.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid-such as Delco
Supreme

Use new brake fluid from a sealed
container
