Start the engine

Engine
Fan
Noise
This vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air to cool the engine. In most every day
driving conditions the clutch
is
not
engaged. This improves
fuel
economy
and reduces fan noise. Under heavy vehicle loading, trailer towing and/or
high outside temperatures, the fan speed increases when
the
clutch engages.
So
you may hear an increase in fan noise. This
is
normal and should not be
mistaken
as
the transmission slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and
the
clutch disengages.
You
may also hear this fan noise when you start the engine. It
will
go
away
as
the
fan
clutch disengages.
