Checking Coolant - Cadillac 2003 CTS Owner's Manual

Checking Coolant

The coolant surge tank and pressure cap are located
on the driver's side of the vehicle, toward the rear of
the engine compartment. See "Engine Compartment
Overview" in the Index for more information
on location.
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
--
little when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD/FROID line on the side of the surge tank. Follow
the arrow from the top of the tank down the side to the
horizontal mark.
If the Check Coolant Level message in the DIC comes
on and stays on, it means you're low on engine coolant.
See "Check Message, Coolant Level" in the Index for
more information.
