Adding Coolant - Pontiac G5 2010 Owner's Manual

Checking Coolant
The coolant surge tank is located in the engine

Engine Compartment Overview on page 6-12 for more
information on location.

WARNING:
{
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap — even a
little — when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL line.

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 6-27 for instructions on "How to
Add Coolant to the Coolant Surge Tank."
