Coolant Surge Tank Pressure Cap - Chevrolet 2005 Classic Owner's Manual

Adding Coolant
If you need more coolant, add the proper DEX-COOL
coolant mixture at the coolant surge tank, but only
when the engine is cool. If the coolant surge tank is
empty, a special fill procedure is necessary. See Engine
Overheating on page 5-22 and Cooling System on
page 5-24.
CAUTION:
{
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank 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.
When replacing the pressure cap, make sure it is
hand-tight.

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

information on location.
