Engine Overheating - Buick Regal 2011 Owner's Manual

10-22 Vehicle Care
3. Fill the coolant surge tank with
the proper DEX-COOL coolant
mixture to the indicated
level mark.
4. With the coolant surge tank
pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. Watch out for the
engine cooling fans.
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 indicated
level mark.
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 several indicators
to warn of engine overheating.
You will find an engine coolant
temperature gauge on the vehicle's
instrument panel cluster. See
Engine Coolant Temperature Gauge
on page 5 10.
If it is decided not to lift the hood
when this warning appears, but
instead get service help right away,
see Roadside Assistance Program
on page 13 6.
If it is decided to lift 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.
