I have to replace the fan clutch on my '74 CJ-5 and I have no idea how to do it. From what I have been told it should be a very easy thing to do but I have not been able to find any instructions on exactly how to do it. I have the new part but I don't know what the procedure is to replace the old one. I'd appreciate it if someone could clue me in on how to replace the fan clutch. By the way, my CJ has the 304 V-8 engine with the two barrel. Thanks.
