Engine Overheating - GMC 2011 Terrain Owner's Manual

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.
Vehicle Care
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.
