2005 4.0L V6
There is a metallic chirping / squealing noise coming from the engine area over 2000RPM, so every time I shift or I'm on the highway, it's constant.
This started a while ago, and I have changed, in this order:
-Alternator
-Belt
-Belt tensioner
-Fan clutch
-Idler pulley
Still no change. I'm at a loss. It seems like it could be anything turned by the belt or even the aftermarket parts I've already replaced, which is frustrating.
It's pretty annoying / embarrassing to drive at the moment. Any ideas?
I feel like the water pump might be the next thing to check.
