How do you install ac belt on 2000 Chevy pick up?

Answer 1

You will first have to remove the plastic air intake tube from the air filter box to the intake manifold or possibly take it loose from the intake and raise it up. This is to gain access to the tensioner for the larger serpentine belt. Locate your belt routing sticker and get familiar with it before you remove the belt, if no sticker is present, make a sketch or take some digital pictures. Use a 15mm wrench on the bolt in the center of the tensioner pulley and rotate it clockwise until you get enough slack to slip the belt off of it. Now you go under the front of the truck and pull that belt over out of the way. Next you put your AC belt all the way over the big pulley (harmonic balance), till it is between the pulley and the engine, this is to give you plenty of slack to put it in place on the AC pulley. Then you insert a 3/8" drive into the tensioner and pull it down, while you hold that in one hand, use your free hand to work the belt into place on the larger pulley, then slowly release the tensioner. Check that the belt is straight and in all the grooves. Now you are ready to reinstall the longer belt reverse the way you took it off. I really hope this helps. (this job can be very easy or very hard).
