Adding Coolant; Coolant Surge Tank Pressure Cap; Engine Overheating - Cadillac DeVille 2005 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.
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 the arrow
lines up with the tube.

Coolant Surge Tank Pressure Cap

®
Notice: If the pressure cap is not tightly installed,
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
Compartment Overview on page 5-12 for more
information on location.
