2004 Grand Cherokee Laredo (4.0) AC bypass

Have a locked up ac compressor. The belt diagram under the hood shows an option for "no AC" belt routing but cant seem to find any info on belt length. Hoping just a quick temp fix to get me through a couple weeks. Thanks for any info.

If no replies, try this-

Route a string through the pulleys, tie off at proper tension, remove and then measure. It will get you in the ball park and better than just a wild ass guess.

Re: 2004 Grand Cherokee Laredo (4.0) AC bypass

Thanks for the reply, that got me in the ballpark and got it in two takes. I ended up determining it was a 75" 6 rib belt on my 04', 13" shorter than routing with AC. I used a Duralast 750K6 ($23 at Autozone) and everything working fine routed as shown on the sticker above the radiator for "No AC". I heard comments that defrost depends on AC compressor, seems to be working fine and plenty of heat on dash.

In defrost position the AC compressor will be switched on automatically to remove the moisture from the air, so that the window defogs rapidly. So not a real problem for you.
