How to diagnose a whining noise

Asked by Jan 27, 2017 at 11:29 AM about the 2006 Dodge Grand Caravan SXT

Question type: Maintenance & Repair

I have a whining noise that gets louder and slightly changes pitch directly
related to engine RPM.  It is the same with the engine cold or warmed up.  It
does not change with more electric draw, like with lights on.  It doesn't
change when turning the steering wheel.  The water pump is pretty new and
is not leaking.  No warning lights.  No loss of power.  Any hint on how to
diagnose this?

Probably one of the accessories that is run off the serpentine belt. A long screwdriver or stethoscope will help pinpoint the area. You can also remove the serpentine belt and spin the pulleys too....http://www.harborfreight.com/mechanics-stethoscope- 69913.html

The whining noise is more than likely coming from the power steering pump. Common sound, but if the power steering is giving you any problems, then you would want to replace the ps. pump.
