Checking Coolant - GMC Denali 2004 Owner's Manual

Checking Coolant

The coolant surge tank is
located in the engine
compartment on the
passenger's side of the
vehicle. See Engine
Compartment Overview on
page 5-10 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 — even a 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 mark.
If your vehicle is equipped with a low coolant sensor,
and the LOW COOLANT LEVEL message comes
on and stays on, it means you're low on engine coolant.
See "Low Coolant Level" under DIC Warnings and
Messages on page 3-57 .
