Adding Coolant; Coolant Surge Tank Pressure Cap; Engine Overheating - Cadillac CTS 2008 Owner's Manual

Adding Coolant

If more coolant is needed, add the proper DEX-COOL
coolant mixture at the surge tank, but only when the
engine is cool.
CAUTION:
{
You can be burned if you spill coolant on hot
engine parts. Coolant contains eythylene 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.

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 5-14 for more
information on location.
