This thing has been going for a few years. Started out as a chirp. Replacing the belt every 5-6 months (at $40 a pop) fixed it for a couple years. Been thru 4 or 5 belts, now I almost have 100,000 miles on it.
A new belt quit fixing the problem. Now I have an all out squeal that won't go away. It's not bad at idle, but after 1500 RPM its bad. Dealer replaced the tensioner and idler pulley twice. I replaced the alternator. Their diagnosis, they thought that might be it, it wasn't.
Sounds like the squeal is in the center of the engine. So, now they want to replace the water pump at $400.
Any thoughts or help on this? It's really starting to drive me nutz,,,
I just ordered a gatorback belt to try, before sinking more money into high dollar guesses (parts).
ETA: it's a 4.0 V-6 with A/C
