(Don't press down while turning the pressure cap.)
You can remove
the coolant surge
tank pressure cap
when the cooling
system, including
the coolant surge
tank pressure
cap and upper
radiator
hose, is
no longer hot.
Turn the pressure
cap slowly to the
left until it first
stops.
If you hear a hiss, wait for that to stop. A hiss means there is still some
pressure left.

Help keep the proper engine temperature.
0 Let the warning lights 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
.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. Use GM
.Engine Coolant Supplement. (‘sealer) with any. complete coofant change.
If you use this mixture, you don? need to add anything else.

your warranty. Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
Adding Coolant
I
Your cooling system when hot is under a lot of pressure. If the “ENGINE
COOLANT
LOW” message should appear on the Driver Information
Center,
you will need to add coolant.
If the “ENGINE COOLANT LOW” message does not appear, the
coolant is at the proper fill level.
