Engine Overheating - GMC 2014 Terrain Owner's Manual

This will allow any pressure still
left to be vented out the
discharge hose.
2. Keep turning the pressure cap
slowly, and remove it.
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.
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
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 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.
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
The decision may be made not to lift
the hood when this warning
appears, but instead get service
help right away. See
If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface.
