Ac Compressor Slide Bolt on 2.5 (Page 1/1) McMatt12 APR 16, 06:21 PM My 86 2m4 has an awful squeal. The serpentine belt seemed to be loose so I got under the car to tighten it and found that the compressor does not have a bolt holding the compressor to the bracket. I've been looking everywhere for the size and type of bolt with no result. I figured I'd check to see if anyone knows the size/type before I took it out of my 2m6. Thanks.
