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.
II Heater and radiator hoses, and
L 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.
Engine damage from running
your
engine without coolant isn't
covered by your warranty.

How to Add Coolant to the Coolant
Recovery Tank
(or the Coolant Surge
Tank):
If you haven’t found a problem yet, but
the coolant level isn’t at or above FULL
COLD,
add a 50/50 mixture of clean
water
(preferably distilled) and a proper
antifreeze at the coolant recovery
tank
(or coolant surge tank). If you have the
coolant surge tank, be sure
the cooling
system, including the coolant surge
tank
pressure cap, is cool before you do it.
See How To Add Coolant to the 2.2L L4
Engirze at the Radiator or How to Add
Coolant
to the 3.1L V4 Engine ut the
Coolant
Surge Tank later in this section.

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 cool an^
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 50150 mix
of clean water and a proper
antifreeze. In cold weather, water can freezt
and crack the engine, radiator,
heater core and other parts Ise
the recommended coolant.

How to Add Coolant to the 2.2L LA
Engine at the Radiator: .
1. You can remove the radiator pressure
cap when
the cooling system,
including the radiator pressure cap
and 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, 3. Fill the radiator with the proper mix,
but now push down as
you turn it. up to the base of the filler neck.
Remove the pressure 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,
see the Index under
Engine Overheating.
The proper coolant for your Chevrolet
will:
Give freezing protection down to
Give boiling protection up to 262°F
Protect against rust and corrosion.

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.
If you have a 2.2L LA engine, your
engine coolant system will have a
coolant recovery
tank. If you have a
3.1L V6 engine, your engine coolant
system will have a coolant surge
tank.
There are important differences between
these two cooling systems. Read this section carefully.

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 hot,
the level should be near the H mark.
When the engine compartment is cool,
the level should be near the
C mark.

Tires
We don’t make tires. Your new vehicle comes with high quality tires made by a
leading tire manufacturer. These tires are warranted by the tire manufacturers and
their warranties are delivered with every
new Chevrolet. If your spare tire is a
different brand than your road tires,
you will have a tire warranty folder from each
of these manufacturers.

CAUTION
Poorly maintained and improperly used tires are dangerous. 1
’ - Overloading your tires can cause overheating as a result of too much
friction. You could have
an air-out and a serious accident. See the Index
under hading Your Vehicle.
Underinflated tires pose the same danger as overloaded tires. The resulting
accident could cause serious injury. Check all tires frequently to maintain
the recommended pressure. Tire pressure should be checked
when your
tires
are cold.
