Coolant Surge Tank Pressure Cap; Engine Overheating - Chevrolet 2008 Cobalt Owner's Manual

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 and fully seated.

Coolant Surge Tank Pressure Cap

Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may occur.
Be sure the cap is properly and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. See Engine
Compartment Overview on page 5-12 for more
information on location.

Engine Overheating

You will find an engine coolant temperature warning
light on your vehicle's instrument panel. See Engine
Coolant Temperature Warning Light on page 3-34 for
more information.
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.
Notice: If your engine catches fire because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
