Engine Overheating - GMC 2012 Terrain Owner's Manual

10-20 Vehicle Care
3. Fill the coolant surge tank with
the proper DEX-COOL coolant
mixture, to the COLD FILL line.
4. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Watch out for the
engine cooling fan(s).
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL coolant mixture to
the coolant surge tank until the
level reaches the COLD
FILL line.
5. Replace the pressure cap. Be
sure the pressure cap is
hand-tight.
Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is not at
the proper level, repeat Steps 1
through 3 and reinstall the pressure
cap. If the coolant still is not at the
proper level when the system cools
down again, see your dealer.

Engine Overheating

The vehicle has an indicator to warn
of engine overheating. There is an
engine coolant temperature warning
light on the vehicle's instrument
panel. See Engine Coolant
Temperature Gauge on page 5 10.

The decision may be made not to lift
the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program (U.S. and
Canada) on page 13 7 or Roadside
Assistance Program (Mexico) on
page 13 9.
If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan(s) are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice: Engine damage from
running the engine without
coolant is not covered by the
warranty.
