Ronald, This is just my problem, My engine fan doesn't engage at all in
driving or in traffic, the only time I have my engine fan to engage is on
cooler mornings.I would go out and crank up my truck and leave it for 10-12
minutes idling to warm up.When I would pull out of my drive, I would wind
the motor up to 2000 rpm and shift.At that point, the engine fan disengaged
and I never heard it again.Since it has been real hot, I don't even get it
first thing in the morning.
