you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your vehicle will:
0 Give freezing protection down to -20°F (-29”C), or -34°F (-37°C) in
0 Give boiling protection up to 258°F (125 “C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.

and for vehicles with the cold climate option.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze
that meets “GM Specification 6038-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
“GM
Specification 603%”’ with a complete coolant flush and refill. If you use
this mixture,
you don’t need to add anything else.

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, an
AC@ cap is
recommended. See
“Service Replacement
Part and Filler
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 coolant reaches a preset temperature.
When you replace your thermostat, an
AC’ thermostat is recommended.
