Cooling System; Engine Coolant - GMC Acadia 2013 Owner's Manual

10-12 Vehicle Care

Cooling System

The cooling system allows the
engine to maintain the correct
working temperature.
1. Radiator Pressure Cap (Under
Sight Shield)
2. Engine Coolant Recovery Tank
3. Engine Cooling Fans (Out
of View)
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 mi)
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.
