Cooling System - Chevrolet 2007 Equinox 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 Fans
B. Coolant Surge Tank
358
CAUTION:
{
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. 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 radiator
hoses, heater hoses, radiator, water pump,
or somewhere else in the cooling system.
