Downloaded from www.Manualslib.com manuals search engine 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 get
a little too hot when you:
Climb a long hill on a hot day.
0 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. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and
open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D) for automatic transaxles.
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.

vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

don't do anything else
until it cools down.
I
The coolant level should be at the FULL COLD mark. 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.
I NOTICE:
I
Engine damage from running your engine
without coolant isn't covered by your warranty.
If there seems to be no leak, with the engine on, check to
see
if the electric engine fm is running. If the engine is
overheating, the
fan should be running. If it isn't, your
vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine When to Check and What to Use
Refer to the Maintenance
Schedule to determine
how often you should
check the fluid level in
your clutch master
cylinder reservoir and
for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids
and Lubricants” in the
Index.
How to Check
You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap
off. If the fluid reaches the step inside the
reservoir, the fluid level
is correct.
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, see “Engine Overheating” in the
Index.
The proper
coolant for your Chevrolet will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F (128°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clcn11 w:akr (preferably
distilled)
and one-half antifreeze that meets “GM
Specification 1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant tllrsh
and refill. Use
GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill. If ~OLI use
this mixture, you don’t need to add anything else.
I NOTICE:
, If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty. Too much water in the
mix can freeze
and crack the engine, radiator, heater core and
other parts.
Adding Coolant
6-22

Downloaded from www.Manualslib.com manuals search engine To Check Coolant To Add Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
When your engine is cold, the coolant level should be at
the FULL
COLD mark.
See “Low Coolant Light”
in
the Index. When replacing
the pressure
cap, make sure it is tight.
Surge Tank Pressure Cap
NOTICE:
Your surge tank cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
If this light comes on, it means you’re low on engine
coolant. When
you replace your surge tank pressure cap, a GM
cap is recommended.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps to go on and
off, or
in some cases to remain off. If this happens, have
your headlamp system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker
opens and closes,
protecting the circuit
until the problem is fixed.
