Adding Coolant; Coolant Surge Tank Pressure Cap; Engine Overheating - Pontiac G5 2009 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 5-27 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.

Coolant Surge Tank Pressure Cap

®
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. See Engine
Compartment Overview on page 5-12 for more
information on location.

Engine Overheating

You will find an engine coolant temperature warning
light on your vehicle's instrument panel. See Engine
Coolant Temperature Warning Light on page 3-33 for
more information.
