0 Let the warning lights and gages work as they should.
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 use a recycled coolant conforming to “GM
Specification 6038-M,” with a complete coolant flush and refill. If you use

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, an
AP cap is
recommended. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.
