Radiator Pressure Cap; Engine Overheating - Pontiac 2005 Grand Prix Owner's Manual

CAUTION:
{
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
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.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see Cooling System on page 5-30.

Radiator Pressure Cap

Notice: The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the overflow tube on the radiator filler neck.
The radiator pressure cap is located in the front of the
engine compartment on the passenger's side of the
vehicle, near the diagonal cross brace. See Engine
Compartment Overview on page 5-12 for more
information on location.

Engine Overheating

There is a coolant temperature gage and a warning light
on the instrument panel that indicate an overheated
engine condition. See Engine Coolant Temperature
Gage on page 3-43 and Engine Coolant Temperature
Warning Light on page 3-43.
