Serpentine Belt on 2000 TJ Sport

Ok, so here's the deal. My serp belt decided to snap yesterday as I was driving. I went to go get a new belt, but apparently the one the auto store had wasn't the right one. I've also looked for the routing of the belt, but all the schematics I've found were for 99 and below wranglers. And they have the A/C above the alternator. On my 2000 wrangler, the A/C is located underneath the powersteering pump.

Second question....on the alternator, there's what looks to be a tension arm, or some sort of arm, pulley on the bottom of the alternator. It looks like it was once a hard plastic, but it's now just like ground down and broken plastic...anyone know what that is?

And does anyone have the belt routing for a 2000 wrangler with A/C or pictures...and the part number on the belt! Thanks alot!!

Darren

This page : JEEP WRANGLER Belt Routing Diagram from Best Value Auto Parts shows 3 different diagrams for belt routings for 2000 wrangler.

The pulley is called the belt tensioner pulley, I believe.

I didn't drive my 2000 TJ to work today, or I could have taken a pic. Sorry.

ok, so i got the routing figured out, but I found out the tensioner pulley disentigrated into about 500 pieces. Are they easy to replace? I found a completely new tensioner and pulley for $45 at my parts store.

I've never done it, but it sounds like it should be easy :

"Once the belt is off, unscrew the bolt in the center of the pulley. Or remove the entire bracket with the pulley on it and do it in a vise."

Ok now I recently replaced my serp.....I couldn't get the tensioner to loosen up to get the belt off. So alas I cut it, go down and get a new and WTF it doesn't fit. I scratch my head and try again....still no go. It seems too small. Fianlly I got to the Jeep dealer and say gimme serp for a 99 TJ with ac etc. He hands me the belt and it's a lot larger. I think Hmmmm I go hoem and waaa laa it fits. So I look over the routing of the belt and thank god I took a pic of it be fore taking the old one off and find the old one was the WRONG SIZE, and how the person got it on and amde it work was beyond me.....since it was no where near or around the tensioning pulley. Now it's the right one and sounds much quieter and smoother. So maybe yours is the wrong one also.

Well I replaced the belt, and tensioner pulley. It was pretty easy actually..took about 30 mins. Then I go for a test drive and my idler pulley decides to seize up. So I get a new one of those, put it on and it runs like a dream. Pretty easy though when it's all said and done.
