I need some help figuring out which of my engine pulleys is squeaking. I drive my truck almost every day, but this week I let it sit for about 3 days before firing it up. Well the bastard starts squeaking like a cricket upon start up, I open the hood and am unable to pinpoint the source, I tried the screwdriver method, the hose method, trying to pinpoint it but I can't seem to find it.
Is there some trick to do to isolate each pulley to see if it is the cause?
The A/C compressor has always had a slight chirp, and that particular chirp is still present even with this new one. It almost sounds like either the alternator (about 5 months old) or the power steering pump. Once I get on the gas, it goes away, but when at idle or dropping rpm it's very audible.
The belt looks ok, has decent tension, but I noticed that the tensioner is hopping about while the engine is running, not sure if that is normal or not.
Any tips, tricks, advice would be appreciated. TIA
