Engine Overheating - Buick 2011 LaCrosse Owner's Manual

3. Fill the coolant surge tank with
the proper mixture to the mark
pointed to on the front of the
coolant surge tank.
4. With the coolant surge tank 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 mark pointed to on
the front of the coolant
surge tank.
5. Replace the cap. Be sure the
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.

Engine Overheating

The vehicle has several indicators
to warn of engine overheating.
There is a coolant temperature
gauge and a warning light on the
instrument panel cluster that
indicate an overheated engine
condition. See Engine Coolant
Temperature Gauge on page 5 11
for more information.
Vehicle Care
You may decide 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 you do decide 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, 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.
