I have an '04 Trailblazer with the 4.2L. I was in the process of replacing the A/C Clutch bearing and decided to go a step further and try to find the clutch kit or assembly. If I can a kit that includes the clutch, pulley, and coil that would be great. I called an auto a/c compressor parts supply store and they were unable to find a kit in their catalogs. The clutch has some meat left on it but not much. Worst case scenario I clean up the clutch plate and pulley and just put a new bearing in. The only other thing I can think of is buying a new or rebuilt compressor and robbing the parts off it but its not the most cost effective option. I don't want to evacuate the system to replace the entire compressor when this one works just fine. Does anyone know if there is a clutch kit for the Sanden TRSA12 P/N 25825339 Model# 3450???
A little reasoning behind why I want to do the a/c clutch-
I'm in the process of doing a bunch of 100,000 work so I can get another 100,000 miles out of it. If I can do it now while I have the front of the motor tore apart I'd like to do it now. The water pump was leaking from the weep hole so I'm putting all OEM parts in. I have everything just waiting on what to do with the A/C. Any help is appreciated!
-radiator shroud (other one had slice from fan blade)
-idler pulley and tension pulley
-the list goes on...
