Pontiac 2004 Grand Prix - Manual (Page 309)

{ 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. Don’t 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 5-32 .
Radiator Pressure Cap
Notice: Your radiator cap 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, near
the diagonal cross brace. See
Engine Compartment
Overview on page 5-12 for more information on location.
Engine Overheating
You will find a coolant temperature gage and a warning
light concerning an overheated engine condition on
the instrument panel cluster. See
Engine Coolant
Temperature Gage on page 3-39 and Engine Coolant
Temperature Warning Light on page 3-39 .
