Coolant Surge Tank Pressure Cap; Engine Overheating - Cadillac XLR-V 2006 Owner's Manual

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.
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, press down and turn it
clockwise until you hear a clicking sound. Make sure the
cap is hand-tight and fully seated.
