So, this noise started recently. It's an odd squeaking sound as you can tell from the video. I replaced the belt, idler pulley, and tensioner pulley to no avail. The video was taken after I replaced the parts.

Has anyone experienced this noise before or have any clue as to what it may be? Any help will be appreciated.

 

It could still be the belt. I went through 3 or 4 different belts and all of them squeaked after a while. I finally got a goodyear gatorback belt and it's been fine for 4 months/4000 miles.

 

Sounds like the tension spring inside the belt tension assembly. Spray some WD40 inside on the spring and see if it stops. If so then replace the assembly.

 

I think it sounds too "fast" to be the tensioner. Try getting a gatorback belt. Mine sounded exactly the same and the gatorback belt fixed it.

 

Could be your idler pulley. I had to replace the one on my Ram yesterday. Close to the same sound. I thought it was the alternator again, but my mechanic used his stethoscope and pinpointed it. Bought a new one, changed it out in about 10 mins and all's good.

 

Hey guys, sorry it took a while to get back with a reply. So I've been driving it and it seemed fine, but I still couldn't figure it out...until tonight.

I was driving home and saw that I was starting to overheat, luckily I made it home without it going all the way the the 260 mark. However, got back home to find that my water pump had taken a dump on me as coolant was all over my engine bay.

Looks like I have some fun ahead of me... never replaced this myself before, but lets say I'm not gonna pay someone to do it (again). Sounds like a good project for me.

 

It's not really that difficult. The 2 hardest things are getting the fan off, and getting that little bypass hose back on.

 

Looks like I need to flush my system out too as the water pump had been grinding quite a bit and possibly sending little metal pieces everywhere.
