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.
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when the engine is cold
and follow the steps under “Adding Coolant” for the proper way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to add extra
inhibitors or additives which claim
to improve the system. These
can be harmful.

Downloaded from www.Manualslib.com manuals search engine 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. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.
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 co6lant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

What To Use
When you need windshield washer fluid, be sure to read the manufacturer’s
instructions before use. If you will be operating your vehicle in
an area
where the temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.
To Add
Open the cap labeled
WASHER FLUID
OmY. Add washer
fluid until the tank is
full.
~ NOTICE:
~ 0 When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
’ 0 Don’t mix water with ready-to-use washer fluid. Water can
cause the solution to freeze and damage your washer fluid
tank and other parts of the washer system. Also, water
doesn’t clean
as well as washer fluid.
0 Fill your washer fluid tank only 3/4 full when it’s very cold.
This allows for expansion, which could damage the tank if it is
completely full.
Don’t use radiator antifreeze in your windshield washer. It
can damage your washer system and paint. -
