Cooling System - Pontiac Sunfire 2003 Owner's Manual

Cooling System

When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fan
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,
don't do anything else until it cools down. The vehicle
should be parked on a level surface.
The coolant level should
be at the FULL COLD
mark. If it isn't, 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.
