GMC 2008 Envoy Denali, Owner'S Manual

Page: 321 / 468

Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
Notice: If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. See Recommended Fluids and
Lubricants on page 6-12 for more information.
Checking Coolant
The engine coolant
recovery tank is in the
engine compartment on
the passenger’s side of the
vehicle. The cap has this
symbol on it. See Engine
Compartment Overview
on page 5-12 for more
information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at FULL
COLD, or a little higher.
