Coolant Surge Tank Pressure Cap; Engine Overheating - Chevrolet 2005 Aveo Owner's Manual

Adding Coolant
If the level falls below the MIN (B) mark, add the proper
coolant mixture at the surge tank, but only when the
engine is cool. If the surge tank is empty, a special fill
procedure is necessary. See Cooling System on
page 5-26 for instructions on "How to Add Coolant to
the Coolant Surge Tank."
CAUTION:
{
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.

Engine Overheating

You will find a coolant temperature gage on your
vehicle's instrument panel cluster. See Engine Coolant
Temperature Gage on page 3-23.
If Steam Is Coming From Your Engine
CAUTION:
{
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
