AC belt on 1999 Chrysler 300M
When you replace the AC belt you really should replace the serpentine belt as well, since you will have to take it off already. If you don't do it now it is inevitable that you will have to replace it in like 3 weeks anyway : )
You need to first remove the serpentine belt by loosening the nut in the center of the idler pulley. After that you will need to loosen the push bolt on the side of the idler pulley. The hub bolt is a 15mm size and the push bolt on the side of the tensioner is a 13mm I think. After you loosen it sufficiently, you will need to pull off the old belt.
Next you will need to loosen the tensioner pulley for the AC belt as well. It is the same process. The main issue is space. You will most likely need to raise your car to get at the right angles to loosen these pulleys.
Once you loosen the idler pulley in the same manner as you loosened the other, you can slip the AC belt onto the back of the crank pulley and route it as the diagram under your hood instructs you. Next tighten up the idler pully in the opposite way as you loosend it...tighten up the push bolt until the belt play is within factory specifications, then tighten the hub bolt in the center of the pulley. Do the same for the serpentine belt and you should be up and running in no time. I just performed these tasks on my 2000 300m and I wish someone would have told me this before I started my project. Hope this helps, Good Luck!
