There is a whine that seems to be coming from the pulley system on the forward part of my engine. I only really hear it at idle but I suspect thats due to reduced engine noise. It's not the sound of a slipping belt - I don't think. It really sounds more like a corroded bearing of some sort either in my circulation pump or else where. There is no play or movement in any of the pulleys. I've tried listening with the engine running and it's impossible to tell where it's coming from. What's the best way to go about this?
After double checking proper belt tension My plan is to...
1) remove the power steering pump belt and see if sound goes away Otherwise...
2) remove the altenator belt (this won't hurt anything right?) and see if sound goes away. Otherwise...
3) replace circulation pump (< year old) and see if sound goes away..
Otherwise??
Is there somthing here maybe that I am overlooking that could make this sort of sound? It's definitely a reciporical sort of squeaky whinning. I really do suspect that it's my circulation pump. If so, could water intrusion really have corrode out the bearings in less than a year? Would over tension to the belts cause this issue?
Appreciate any help available.
