Hey everyone, first post. Going to make it short.

I have a 2002 lancer ES with around 170k miles. Recently, my battery died. I eventually replaced the battery about a week and a half later. After starting the car, I noticed a slight squealing noise.

It seems like the squealing is only occurring after the front radiator fan turns off every so often. When the fan is running, there is no squealing whatsoever.

Anyone have any ideas on what could be causing this? I'm guessing the belt needs to be tightened but figured I'd check here first. Let me know what you all think!

Thanks!

 

try to locate the source of the squealing...it's pretty hard to determine the cause...squealing stops when fan comes on...is it THAT consistent?

 

I'm guessing it must the fan motor itself or the pulley?
