boy you all had to do a lot more work than I did: I was able to purchase a Dayco 5050658 from advance for $27.99 and install it without removing the AC Compressor Pulley or modifying it in any way...

no picture of my routing because of my HD fan shroud but I borrowed Dave's picture to show my routing:

I have about 200 miles on it with no issues.

Looks like you did this:



Which I got from this thread:

AC Compressor Bypass?


I saw that and thought it could work too, and easier as you say! But there was no mention of a belt size. Given what I went through with the belts, I could have just gone to the store and tried belts until I got it right anyways!

Edit to add, do you know how long that belt is?

yes that is exactly how I routed it, although I didn't see that thread before hand. i got the belt number off of a thread on LOST and just had to figure the routing out myself.

Dayco says the Outside diameter of the belt is 66.41 inches

Just to update, I recently had the A/C clutch go out on my 3.7L '04 Liberty. Bought an 82.5" 6-rib belt from NAPA for about $38. The guy at NAPA told me they don't sell Dayco belts anymore because they're "the cheap ones" and the quality just isn't there.

For those who need to know, with an 82.5" belt, you have to route the belt like the OP did in his first pic. The belt is too long to run it at a 90-degree angle like in KeswickDave's diagram above, which means you will have to remove the A/C clutch assembly. My clutch and bearing were completely blown, so I just pounded everything off. Took about 10 minutes. The compressor shaft that the coil and pulley bearing mount on should look clean and un-marred.

Also - I had to remove my cooling fan and shroud (they are one piece). Just 2 screws and I was able to pull it right up through the top. Well worth the 2 minutes to remove it - you have loads more room to work.

One more thing to note. When I first started playing with the automatic belt tensioner, I wasn't sure I would be able to get the shorter belt on, but it turned out I just wasn't pulling on it hard enough. The 82.5" belt worked great. Good tension. Keeps my Jeep on the road until I get a new A/C clutch.

Sorry to dig up an old thread, but, gonna try and do this tomorrow in the parking lot at work where my jeep has sat for one night already.

Just out of curiosity, my jeep has a mechanical clutch fan, is this part of a tow package or something or is it that just the 02's had the mechanical fan? I got the 82.5" belt to be safe since it seems to be the more common solution.

Never realized how common this issue was...mine was about to go before I got it fixed (she whined like CRAZY). Solid post though!

I know it came with the tow package. I don't have one on my 04, but that doesn't mean they weren't included in the 02 models. The tow package also came with the heavy duty shroud. Mine has the shroud for some reason. It's really big and makes working on the engine harder, but oh well.

Amazing that this thread popped up, my clutch is going and I've been messing with it trying to figure out how to do this. Thanks!

Anyone know the sizes of the bolts for the AC compressor? I have to grab tools from our lab to move it up out of the way in our parking lot.

Also, I'm guessing a 3/4" wrench for the tensioner pulley?

I didn't bother reading this thread... As it offends me.
Your vehicle came with A/C. Why not just get it repaired or replaced?
If you cannot afford the the cost of the repair or replacement parts of an Air conditioning system then maybe you should be driving something cheaper without an A/C system!
Why do vehicle owners always bite off more than they can chew?

Go without your daily Starbucks or other crap that costs money and get your shit fixed.
