Cooling System - Pontiac G5 2010 Owner's Manual

Cooling System

When you decide it is safe to lift the hood, here is what
you will see:
A. Electric Engine Cooling Fan
B. Coolant Surge Tank and Pressure Cap
6-20
WARNING:
{
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling, do
not do anything else until it cools down. The vehicle
should be parked on a level surface.
The coolant level should be at the COLD FILL line. If it
is not, you may have a leak at the pressure cap or
in the radiator hoses, heater hoses, radiator, water
pump, or somewhere in the cooling system.
