    can anyone remember back to 1989?? I have a 1989 gmc 4x4 1/2 ton trhat I want to remove the a/c compressor. what do i need to do? new bracket, shorter belt, different belt tensioner?? I'm prety sure the b.t. has to be moved but it appears i need a different bracket to mount it in the right location. then there is the 40 or 6 groove serpentine belt issue/
    also does anyone know if they make an assembly or parts manual

    thanks for any info


    I have mounted a 1039 body on this chassis. I have a feeling I'm just getting started on the first of many issues. LOL

    which motor does it have and what's the configuration of the accesorries on the belt currently? I want to say if you have the a/c compressor on the drivers side with a 350, you just get a shorter belt and it'll work. Mind you, this is going completely off of memory.

    it has the 5.7 and compressor is on the passenger side. it does show a different belt config in the book and the parts store show a different number on the tensioner for a engine w or w/o an a/c. i thought a new tensioner and belt would work on the old bracket but it doesnt seem to. jst wanted to see if someone could verify that

    thanks:money:

    Welcome to the site. I have an 87 Blazer 1/2 ton 350 with a/c removed but I'm not sure if there is a difference between the 87 and the 89 with the mounting location of the compressor, but I am aware of the body difference.
