Pressure Cap; Engine Overheating - Pontiac 2007 G6 Owner's Manual

Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the surge tank,
but only when the engine is cool. If the surge tank
is empty, a special fill procedure is necessary.
See Engine Overheating on page 342 and Cooling
System on page 345.
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. Do not spill
coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
