GMC 2002 Yukon Denali - Checking Coolant

6-28
Checking Coolant
The coolant surge tank
is located in the engine
compartment on the
passenger’s side of
the vehicle.
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
-- 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 FILL
COLD mark.
If the LOW COOLANT
message comes on and stays
on, it means you’re low on
engine coolant.
See “Low Coolant” in the Index.
