Engine Fan Noise
Your 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 fan
is spinning slower and clutch is not fully engaged.
This improves fuel economy and reduces fan noise.
Under heavy vehicle loading, trailer towing and/or high
outside temperatures, the fan speed increases
as the clutch
more
fully 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 partially disengages.
You may also hear this Fan noise when you start
the engine. It will go away as the fan clutch
partially disengages.
