My serpentine belt fragd into peices a few weeks ago and the mechanic replaced it with a new one. The dam thing screeched from the get go and he said it would get better, said it was a newer design belt from goodyear that was quieter stretched less. Now he says the tensioner may be the problem. Car was working fine before the change now I can't even put the ac on without the screeching. Any ideas? change belt? change pulley? I already tried to adjust the tensioner bolt counter clockwise. Thanks in advance.

 

Was it an OEM part? I used a replacement belt from NAPA with no problems.

 

not sure where he got it but he's the porsche indy around here. I doubt he would use a non oempart.

 

Confirm it is routed properly. I could be mistaken but I think there is a way to put it on that looks right but will cause the belt not to give enough tension.

 

I tried a local indy shop for this and turned out he used a non-OEM replacement belt that was slightly short and caused problems. Got an OEM belt and all was well. Never went back to that guy again.

 

How many miles on your car?

 

Mahle (I think OEM) $26, replaced my own, no issues. Look over in Renntech DIY; pictures posted. The old one was just stretched and glazed would squeal when wet

 

car had 50k miles before the belt gave way; it nearly sliced through some harnesses on either side of the air filter housing. I never knew mahle made belts. I think the old one said continental but the new one says good year. You'd think they make replacement belts similar in size to oem; one thing though is that the ribbed side of the new belt is toothed/ribbed

 

Thanks Al, The indy put the belt on wrong..go figure. This guy has rebuilt engines and changed clutches on my porsches for years. Thats a little disconcerting.

 

Thank you all for your posts, hope I can return the favor.

 

Glad you got it straightened out. Ask me how I thought I remembered there was a right way and a sorta' close way.
