Belt Change Problem

1998 4L V6 A/C 6-rib serp belt.

Does anybody know the proper size? Autozone's computer says 91" (6k910). I got it, And its about the same size as the one I took off, But I can not get it on. I have the tensioner maxed out. I even tried two different brands. Neither will go on. I have changed belts before, and never had an issue. Is there a secret? I would have tried a 92", but they were out of it.

Has anybody run into this before?

Did you tell the counter person you have a V6?

Look at your existing belt where its p/n should (typically is) be still legible somewhere on its outer surface. The last two digits of a serpentine's p/n usually indicate its length in inches.

Check your routing. Just cause it looks right doesn't mean it is

Routing is correct.
He put in v6 A/C with both belts I bought.
No markings on old belt.

I checked the Gates Belt Website. They spec a 91.68" belt also. That .68 shouldn't make a difference. It's still a 910 class belt. I think I 'm just going to get the 92. I hate not using the proper part, but who knows. The previous owner might have put some odd pulleys on it. There is a tremendous amount of adjustment there, I think the 92 should be ok even after it stretches a little.

The comment about the V6 had to do with the Jeep's 4.0L engine being an inline-six, it is not a V6.

Are you sure you're releasing all of the tension from the tensioner? I'd stick with the 91" belt mine went on fine with a 1/2" ratchet...a little wear on that 92" and you'll probably get some squealing. If you're not bottoming out the tensioner try a breaker bar.

The pulley is all the way down. I have the old crank adjuster, 5/8 bolt head i think. a breaker bar would not work on mine.

Sorry, force of habit. The Escape is v6. I'm surprised I didn't say T5. Anyway the belt would be completely different for the 4cyl.

I'll conclude the thread for future reference.

I tried the 92" belt, It was too big. To get the proper 91" belt to fit I made sure the tensioner pulley was cranked all the way down. The belt still wouldn't fit. I either needed stronger thumbs or an extra 1/4 on the belt to push it over one of the smooth shouldered pulleys. to get a little extra I loosened the tensioner pulley center bolt to the point of it almost fell off. It sagged down on the shaft just enough for me to slide the belt on. Tightened everything up, good to go.

I have no idea why it was so difficult. The tensioner pulley center bolt's head was chewed up. So maybe someone replaced that pulley with an odd sized generic.
