Pressure Cap; Engine Overheating - Saturn ASTRA 2009 Manual

9-18 Vehicle Service and Care
Adding Coolant
If you need more coolant, add the
®
proper DEX-COOL coolant mixture
at the coolant reservoir, but only
when the engine is cool. If the
coolant reservoir is empty, a
special fill procedure is necessary.
See Cooling System on page 9-12
for instructions on "How to Add
Coolant to the Coolant Reservoir."
{
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.

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.
See Engine Compartment Overview
on page 9-6 for more information
on location.

Engine Overheating

There is an engine coolant
temperature warning light on your
vehicle's instrument panel. See
Engine Coolant Temperature
Warning Light on page 4-18 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.
