Coolant Surge Tank Pressure Cap; Engine Overheating - Chevrolet Malibu 2007 Owner's Manual

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.
The vehicle must be on a level surface. When the
engine is cold, the coolant level should be at
the FULL COLD mark or slightly higher.
Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the surge tank,
but only when the engine is cool. If the surge tank
is empty, a special fill procedure is necessary.
See Engine Overheating on page 371 and Cooling
System on page 374.
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.
