Radiator Pressure Cap; Engine Overheating - Chevrolet 2003 TraiIBIazer EXT Owner's Manual

Radiator Pressure Cap
Turning the radiator pressure cal ihen 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.
Add coolant mixture at the recovery tank, but be careful
not to spill it.
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
Occasionally check the coolant level in the radiator. For
information on how to add coolant to the radiator,
see Cooling System on page 5-28.
Notice: Your pressure cap is a pressure-type cap
and must be tightly installed to prevent coolant loss
and possible engine damage from overheating.
See "Capacities and Specifications" for more
information.
See Engine Compartment Overview
on
page 5-12 for
