I was wondering if any one else has had this problem. I noticed today my radiator fan makes a whining noise when starting and shutting off. I opened my hook and see that the fan shakes back and fourth about a half inch. I havent driven the car since i noticed this. Is this bad? Can i damage something from driving? Only makes noise when its at a low speed starting up for shutting. When cars started the fan makes no noise. Is it a easy fix? Thanks in advance.

 

pull the fan assembly and check the blades on tight
If thats ok- check shaft looseness from wearout causing excess movement

 

Everything seemed ok but made the noise still. i have sound clips if youd like to hear. only makes noise when fan kicks in. anyplace u can upload clips or email if someone might be able to help?

 

It's possible the bearing is just warn out

 

Lubricate the bearing and see if the noice goes away.

 

Deep Creep thru the opening into the fan motor~ no kidding
its an electrical contact cleaner and water displacer like wd, plus leaves a protective type of oil behind (per their website on those facts)

the bearing is sealed iirc
