1990 3.3 a/c bypass

berettaman200 · March 14th, 2007, 05:59 PM

Ok guys i'm new here but everyone here seems to know wht there talking about. I own a 1990 cutlass ciera sl with a 3300 V6. Outstanding engine. I want to bypass the ac compressor cause it just makes noise and nothing more. However i checked at all the auto stores and they dont make a belt for a non ac cutlass. I have 2 choices. first to get a bypass pulley and rip the compressor out completely or get the measurements for a smaller belt. I wanted to know if anyone here has been through this before and has the dimensions for a belt that bypasses the compressor. I'm sure this has been brought up before but if no one here knows i will just have to measure it myself somehow. Any info would be appreciated. thanks folks.

Well I went outside and took my old belt off and ran a tape measurer through the path that it would be if it was bypassing the Compressor. With the tensioner all the way down with no tension on it my measurement came to 76.5". I think i will have to take off at least 2" to account for the tensioner so it would then be 74.5". Now how do i find that size belt?
