I believe the fan will run all the time. However, if you look carefully you
will note that it is running in the opposite direction of engine rotation.
So, it's not really engaged as much as it is counter-reacting to the drive
pully rotation. It can be stopped by applying slight pressure on the
outside ring with with your fingers, or maybe something more expendable if
you're the careless type (Don't try this at home kiddies). At least mine
does. Once it heats up and locks on then it should rotate with the engine
and pull air through the radiator.
