Coolant Surge Tank Pressure Cap; Engine Overheating - Pontiac 2007 G5 Owner's Manual

Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the coolant surge
tank, but only when the engine is cool. If the coolant
surge tank is empty, a special fill procedure is
necessary. See Engine Overheating on page 290
for instructions on "How to Add Coolant to the
Coolant Surge Tank."
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.
