A CAUTION:
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
DEX-COOL (orange-colored,
silicate-free) antifreeze.
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.
[f you have to add coolant more than four times a year,
lave 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.

.
The surge tank is located next to the engine block on the
passenger’s side of the engine.
The cooling system when hot is under a lot of pressure.
If the CHECK COOLANT LEVEL message appears on
the
DIC, you will’need to add coolant.
A CAUTION:
I’urning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the full cold mark, which is 2.5 inches (60 mm) below
the
base of the fill neck. Use a flashlight as necessary to
see into the tank.

Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and
it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
~~~ ~ ~~~~~~~
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
I NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type
cap and must be tightly instalfed to
prevent coolant loss and possible engine damage
from overheating. Be sure
the arrows on the
cap line up.
If the surge tank pressure cap needs to be replaced, a
General Motors 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.
If your thermostat needs to be replaced, a General
Motors thermostat
is recommended.

The power steering fluid reservoir
is located next to
the coolant surge tank on
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
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.
