When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant surge tank with pressure cap
(B) Electric engine fan
If the coolant inside the coolant surge
tank
is boiling, don’t do anything else
until it cools down.

Howlo Add Coolant to the Coolant
Recovery Tank-2.2L f.4 Engine
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 recovery tank. (See
Coolant in
the
Index for more information about
the proper coolant mix.)

I NOTICE: I
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant. When
the coolant in the coolant
recovery tank is at or above the FULL
COLD 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.

I Hydraulic Clutch
The hydraulic clutch
in your vehicle is
self-adjusting. The clutch master
cylinder reservoir is filled with hydraulic
clutch fluid.
It isn’t
a good idea to “top off” your
clutch fluid. Adding fluid won’t correct
a leak.
A fluid loss in this system could
indicate a problem. Have the system
inspected and repaired.
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.
I Engine Coolunt
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:
Give freezing protection down to -34°F
Give boiling protection up to 262°F
Protect against rust and corrosion.
Help keep the proper engine

should.
What to Use
Use a mixture
of one-half clean water
(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 flush
and refill. If you use this mixture, you
don’t need to add anything else.

Downloaded from www.Manualslib.com manuals search engine 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-2.2L 14 Engine
To Check Coolant
When your engine is cold, the coolant
level should be at
FULL COLD, or a
little higher. When your engine is warm,
the level should be at
FULL COLD or
higher.
To Add Coolant
If you need more coolant, add the
proper mix
at the coolant recovery
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.

Downloaded from www.Manualslib.com manuals search engine Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the fuseblock. An
electrical overload will cause the lights
to go on and off, or in some cases
to
remain off. If this happens, have your
headlight system checked right away.
To access the headlight circuit breaker,
squeeze the plastic clip together and
remove.
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.
