Belt noise - 1996 Chrysler Town & Country

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.

High pitched whining noise, usually means the belts need changing. they are slipping a bit, on the pulleys. Good-Day!

When your drive belt becomes old and stretches so it is no longer tight enough the belt will make a loud squealing noise and will need to be replaced. While the drive belt is off during replacement, you or the mechanic replacing the belt will need to turn each pulley in the system that can be turned by hand to see if any of those are making a metallic noise also. If they make a metallic noise, they are worn out. It is common for a drive belt to wear out and cause this noise.

If it is a belt noise, it because of the slippage between the belt & pulleys. Try replacing with new belts

mcdevito75 here, If you have 1 continuous belt on the engine (serpentine) then the belt could be worn or the tension pully holding the belt tight could be going bad. No noise in Neautral or Park as increased engine speed in these gears over rides the worn part and thus no noise. On a cold engine examine the belt, look for frays / wear from where the belt rides the pullys. If the belt is 2 years old, Change it.

The best way I have found to locate a belt noise is to take a can of WD40 and spray it on the belt when the engine is running. (be careful of the fan) If the noise goes away, you know that it is a belt noise and not a bearing. When serpentine belts dry out they make funny noises. Hope this helps, cheers

change serpintine belt I had one that it made noise changed belt noise went away

The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
