The first thing i would do is try playing with the belt tensioner. it sounds like the belt is lose and when the engine warms up the belt starts to expand and slips off.

The maintenance interval is 60,000 miles, but they usally last quite a bit longer before they fail.
This is a non-interference motor , meaning the valves will not hit the pistons if the belt brakes.

SOURCE: i put a new serpentine

Good Evening, this is kind of odd to run across after doing a few dodge belts today. First off reach down to your pulleys and turn them each by hand and make sure they turn freely. next I would tell you to check your belt tensioner those go bad to the point they can hyperextend the belt. Lastly before putting on the new belt take an old toothbrush and some brake parts cleaner in a can and clean out all the grooves in the pulleys and spray off the smooth ones and let them dry before putting the new belt on. One of the ones I did today had so much belt dressing all over the place and you could swear the belt was still in the grooves when it came off. Let me know how it goes.

What damage does harmonic balance that is bad do

The harmonic balancer is basically a vibration dampened for the engine to eliminate engine vibration. The problem is that sometimes the actual ribbed pulley part on the balancer will separate from the rubber insert and slop around causing the belt the slop around with it. In turn the belt can fray or break. I would say its totally legit what they are saying. Just make sure you always ask to see the part after any work is done. Good luck

Why belt keeps shredding

usually due to a bad bearing, or from resistance due to a frozen or failing assemble, as in power steering, alternator, or an idler. The best way to determine is to remove the belt and check all pulleys for play and resistance.

I have a 1999 Mercury Sable. The only problem I have had with the car is the serpentine belt. It started 3 months ago . . . the engine was overheating and the belt was shredding. I bought a belt tensioner...

take the belt off and carefully check to see if any of the pulleys are out of line and check to make sure they spin smooth and true check for bearing wear and noise in any of the pulleys cause it sounds like simply there is a pulley out of line

Having trouble starting car. The battery is fine since lights still come on. Found a shredded belt. Not sure if it's the alternator belt. Appreciate the help. Marcia

Don't drive the car until you make sure the belt that is shredded is not the water pump belt. YOU could drive but the engine will overheat and have a more costly problem. Two things, if the lights are working but the car is not starting. It could be that the terminals are dirty on the battery AND if the belt that is shredded is the Alternator belt, the battery could be just down on charge. Do to things (1) Find out which belt needs to be replaced and have it replaced. (2) Charge the battery, maybe a friend has a charger, if so have them trickle charge the batter for at least 12 hrs. Less there's some other problem that should take care of it.
