changing an air conditioner belt

Yes, you do have to remove the serpentine belt off to gain access to the A/C drive belt. First loosen the locking nut, then loosen the adjusting bolt to the tensioner pulley assembly until the belt can be removed.

I just got it changed myself. I problem is getting to the belt both serpentine and a/c belt. You have to go under the cars which is hard for chrysler because set to low.
