Try applying some belt dressing on it and if that does not fix it you may need to replace the tensioner because the bearing in it could be becoming bad.hope this helps. also try spraying some w d 40 on the tensioner around were it bolts up and try to get it no the bearing in the tensioner to see if that stops it.could be dry of grease or could be just worn and loose causing the noise. hope this helps thanks

How can I stopped a moise like a belt noise that increase with acceleration in my car


if its a belt noise make sure the belt tensioner is working properly. I`m guessing this has a serpentine belt. if the belt tensioner is working properly then the belt may just need to be replaced. if its not a belt noise then it could be a bearing noise in one of the pulleys which you will have to find which component and repair or replace.

Timing belt needs tighten can it be done?


the tensioner for the timing belt is a hydraulic tensioner and automatically keeps the belt under tension. Because it is hydraulic it can leak oil which gets on the belt and will destroy it.. For this engine to get maximum life out of the belt, it is recommended to replace the crank shaft seal and the cam shaft seals and the hydraulic tensioner. All idler pulleys should be replaced as well as the bearings do a lot of work . If you want a good long lasting job I suggest an accredited shop that does a lot of your make of engine and spend the money now as it will save in the long run.. The noise is more than likely a idler bearing on the way out.

Time to replace the pulley, you can test it by pulling off the belt and spinning the pully with your hand or some compressed air, if it makes noise then its time to replace.

The belts continue to make a loud screeching noises when i drive over 55. Sometimes when the car is idling the belts make noise. Could it be the tension pulley.


it could be the tensioner, water pump, alternator, A/C compressor, power steering, or even a really bad serpentine belt. The only way to be sure is to remove the s-belt and spin-check the pulleys and listen for squeaks or grinding bearings.

Making aloud squeaking noise under the hood


It's most likely a slipping belt. If the belt is heavily glazed, replace it. If it is a serpentine belt, check the spring on the belt tensioner - it should take a significant amount of force to pull it back to release the belt.

Also, check the tensioner pulley, alternator and A/C clutch bearings while you are at it. If there is any roughness or play in the bearings, this could generate noise.

How do I remove and replace the belt tensioner on a 1999 dodge Caravan 3.3L v6


You have to go through the wheel well on the pass side of van. Remove tire. Pull off the inner fender splash panel. Put wrench on right side lug of tensioner lift up(counterclockwise on V6). remove belt. Only one bolt holding the tensioner on the engine. New tensioner is $80. If just making noise , just replace the pulley around $20. Use a Dayco or Gates belt. Goodyear gatorbacks make noise

Car is making loud noise & wont idle


your timing marks must be off for the car not to idle. the timing belt is too tight, that is where the noise is coming from. rule of thumb is you should be able to twist the timing belt to just under 90 degrees on the longest section after the tensioner has tensioned and nut on pully it tightened. tensioners usually tension more than they need to.
