Just had idler pulley, tensioner, water pump, and serpentine belt replaced. Now hear a chirping noise when A/C is on.
Noise from the Alternator/Serpentine Belt area when idle. Louder with A/C.
Noise made by fan belt, when idleing, not a pleasant sound new belt did not help, need ideas to correct offensive sound!
A loud squealing noise from the area of the serpentine belt.
tensioner failed after replacing new belt and tensioner have a low idle chirp. help
Squealing and belt failure multiple times, unknown origin. Have had into the shop at least 10 times
Made those terrible noise that sounded like a huge cricket. Crayon on the serpentine belt was a temp fix. Ultimately we replaced belt and pulley it's been fine ever since.
The serpentine belt has been replaced twice which caused dead battery, water pump and power steering motor replaced. I think the problem is pulley misalignment or the belt tensioner
when car is switched on you can hear a noise on side where alternator is like a speaking noise
during cold startup or turing at slow speed. Nver fixed it.
I have the chirping problem . Replaced all Idler Pulleys as well as tension pulley. Did good for about a month then started again. Don't know if it help but looked close to the drive pulley. looks like it is wobbling a little. Going to take it into the shop and see if that is the problem. This has happen to so many of this model that Chrysler should have been forced to recall these vans and been made to fix it. When mine first started to do this the belt would also come off when it went through very mu water. Changing the belt and the new style pulleys help the problem.
I replaced idle pulley old one ocassionally squeaked put new one on got worse belt still good old hardly made any noise but weather was right so i replaced it
