If you get the overheat warning but see

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.

Engine Overheating
You will find a coolant temperature
gage or the warning light about a hot
engine on your Chewolet’s instrument
panel. You also have a low coolant
warning light on your instrument panel.
See the
Index under Coolant
Temperature Gage for the gage cluster. Steam from
an overheated
engine can burn you badly,
/I‘ even if you just open the hood. Stay
away from the engine if you see or
hear steam coming from it. Just
turn it
off and get everyone away
from the vehicle until it cools down.
Wait until there is no sign of steam
or coolant before opening the hood.
If you keep driving when your
engine
is overheated, the liquids in
it can catch fire. You or others
could be badly burned. Stop your
engine
if it overheats, and get out of
the vehicle until the engine
is cool.

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.

Ifa Tire Goes Flat
It’s unusual for a tire to “blow OU~,)
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:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a
skid and may require
the same correction you’d use in a
skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next section
shows how
to use your jacking
equipment to change a
flat tire safely.

The proper fluid should be added if the
level does not reach the bottom of the
diaphragm when it’s
in place in the
reservoir. See the instructions on the
reservoir cap.
Engine Coolant
The following explains your cooling
system and how to add coolant when it
is low. If you have a problem with
engine overheating or
if you need to add
coolant to your radiator, see the

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.

Radiator Pressure Cap
214
Your radiator cap is a 15 psi
(105 Wa) pressure-type cap and
must be tightly installed to prevent
coolant loss and possible engine
damage
from overheating. Be su
the arrows on the cap line up wi
the overflow tube on the radiato
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.

When the engine compartment is cool,
