Cooling System; Engine Coolant - GMC 2010 Acadia Owner's Manual

10-14 Vehicle Care

Cooling System

The cooling system allows the
engine to maintain the correct
working temperature.
A. Engine Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Cooling Fans
WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is
a leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Notice: Using coolant other
®
than DEX-COOL can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 50 000 km
(30,000 miles) or 24 months,
whichever occurs first. Any
repairs would not be covered by
the vehicle warranty. Always use
®
DEX-COOL (silicate-free) coolant
in the vehicle.

Engine Coolant

The cooling system in the vehicle
is filled with DEX-COOL
coolant. The coolant is designed to
remain in the vehicle for five years
or 240 000 km (150,000 miles),
whichever occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating on
page 10 18.
