How to change serpentine belt


Most serpentine belts are held with tension by a pulley tensioner You must identify which type you have and the required tool or tools to release the tension. The bely routing is on a sticker in the engine compartment or in the owner manual. If you can not fine the routing sticker or don't have the manual, your local parts house should be able to provide you a print out copy. Also it is important to note some parts houses will change the belt for you or lone you the tools to do the job. Don't be afraid to ask for help.

Squeaky noises under the hood


IT COULD BE AN IDLER, TENSIONER, OR THE BELT SLIPPING, THESE ARE SEALED YOU CAN'T LUBE THEM. IT SOUNDS LIKE THE BELT IS SLIPPING, BUT IT COULD BE SLIPPING BECAUSE OF A FAULTY IDLER\TENSIONER. REMOVE THE BELT, MAKE SURE ENGINE IS SHUT OFF, AND YOU HAVE THE KEYS, ROTATE ALL THE PULLEY'S AND THE ALTERNATOR PULLEY THEY SHOULD ROTATE FREELY AND RUN TRUE, AND NO ROUGH FEEL TO THEM, OR THE TENSION COULD BE TOO WEEK TO KEEP THE BELT TIGHT.

I replaced the altenator and the serpentine belt two weeks ago. Now i hear a squeaking noise. I tried a spray for the belt but the noise is still there.


Check your tensioner pulley -- if you do not have enough tension on the serpentine belt, it will slip on the pulleys and cause a squeaking noise (very loud and high pitched). if you push on the serpentine belt with your hand, it should not more more than about an inch -- if it does, you are low on tension. If it does not have any give at all, then you have too much tension, and one of your pulleys might not be turning properly, causing that same noise. If your tension is right, and your car is still making that noise ... and belt dressings (the spray you probably used) are not working to stop it, then it might be a piece of rubber stuck on one of the pulleys, but this usually will not make that sound ... just smoke and a burned rubber smell.

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.

2006 Toyota Corolla LE. Loud squeaking coming from serpentine belt area after I start the engine cold. Changed the belt recently but still noice persist. Loud squeaking goes away after driving for 3-5...


It is probably the tensioner pulley that's gone bad. It can be replaced separately, if you can purchase the pulley separately. As to how to go about changing it in such a small space, it's definitely possible, with the right type of tools. That's why mechanics have so many different shapes and lengths of the same size tools.

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.

While driving my 2000 Plymouth Neon the front drivers side squeaks, we replaced the serpentine belt and the problem got worse... now every once in awhile the underneath of the car sounds like a cross...


Remove the belt and check all the pullies. the should turn freely and shouldn'have any side to side play. With the exception of the power steering pump, it will pull out alittle this is normal. Also check the tensioner, this should move back and forth smoothly and have the same tension all the way. Some to look at before you remove the belt is the alignment of the belt and pullies. They should be strasight with each other. If one looks like it is leaning it is bad. especially the tensioner. It can lean at the pulley and at the mount
