In mid-Ferbruary 2008, I had a serpentine belt replaced as well as a tensioner at a local auto repair shop here in Cleveland, Ohio. I have a 1998 Dodge Caravan SE, 3.3. Two weeks later, the belt loosened, but didn't fall completely off. I was lucky enough to be able to carefully drive my Caravan back to the shop. They fixed it for free. I assume they didn't put it on right the first time, maybe not enough tension on it.
I just had the hood open yesterday to do my weekly maintenance, such as checking the fluids, etc., and I seen the belt as it is in the picture linked above. Must be one bad spot that aligned itself up just right this time that I can see it. Is this worth a trip back to the shop, or is it not bad enough to worry about? Looks pretty impressive to me, and I can even see what looks like a slight crease across the belt.
I have a hunch they put the same belt back on that just came loose, that got damaged when it was coming loose.
Thanks.
