whining, humming 1998 eeplorer sport

[drummerone]

There is a whining, humming sound which I thought at first was the A.C. compressor. It happens when the car is warmed up. But pinpointing the noise seems to be on the passenger side area radiator or condenser area. Fluids are good and no overheating issues... Thank you in advance for any help in this matter.... John

Alternator bearing, #1. Belt Idler Pulley or Belt Tensioner Pulley, #2. Water pump bearing, #3. Suspects in that order.

Remove belt, start engine, if noise is gone, it originates OUTSIDE the engine. Lucky you! Don't leave it run too long, like, 30 seconds max. imp
