WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-

near the blades of the cooling fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.
