Engine Overheating - GMC Equinox 2010 Owner's Manual

3. Fill the coolant surge tank with
the proper 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 starts
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 mixture to the
coolant surge tank until the level
reaches the line pointed to on
the front of the coolant
surge tank.
5. Replace the pressure cap.
Be sure the pressure cap is
hand tight and full seated.
Notice: 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.
If coolant is needed, add the proper
®
DEX-COOL coolant mixture at the
coolant surge tank.
Vehicle Care

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 Gage on page 4 15.
Decide whether to lift the hood
when this warning appears, or get
service help instead.
If lifting the hood , make sure the
vehicle is parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
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.
