Buick 2010 Lucerne Automobile User Manual


 
If the coolant in the recovery tank is constantly low, you
should have a dealer/retailer service department
inspect the vehicle for leaks.
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.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a warning light about a hot engine as well
as an engine coolant temperature gage on the
instrument panel cluster.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
See Roadside Assistance Program on page 8-7.
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, 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.
Notice: If the engine catches fire while driving with
no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by
the vehicle warranty. See Overheated Engine
Protection Operating Mode on page 6-37 for
information on driving to a safe place in an
emergency.
