Cooling System - Chevrolet 2005 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
5-26
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 line (surge
tank seam). 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.
