I am getting the short one JK8 1223 V-Belt but only getting one year / 12,000 miles out of them. They start slipping up grades towing with A/C on. Any other belts or?



Thanks Jeff

If you're only getting 1 year before they start slipping under load, you should look at replacing the tensioner. If it isn't applying enough tension, then the belts would start slipping.

On edit: did you say V-belt? It's supposed to be a serpentine belt.

Sorry its a serpentine belt, I did change the tensioner last time. Any other belts or is Motorcraft the way to go?

I've been using a Gates belt (don't remember the number.) Just replaced the first replacement when the tensioner went out of alignment, shredded the belt and grabbed the dipstick.

are you sure your getting the short belt?

the 10th digit in your vin is supposed to determine what belt you need. if its an x its about 2 inches shorter than the other belt.
