Re: Fix and Sale 72 GMC 3/4 ton 4x4 K2500
Started working on removing the driver side bedside. Was able to get the wheel tub off in a reasonable time. Not so much on the actual bedside bolts, most of them just want to spin. I have soaked them in Kroll oil which I usually have good success with. If I can not get them off this evening I will probably just spot weld a flat bar to the top of the heads and just break them off. While I was waiting on Kroll oil to do its job I started up the truck to see if I could detect any exhaust noise coming from a possible leaking exhaust manifold gasket. Before I could even look into that, I noticed a noise from the fan shroud. So I turned it off and found that the fan was hitting around the bottom. Tried adjusting the fan shroud a little and no luck, so I removed it for time being. After removal it looks like the P.O. might have cut down the shroud a bit to accommodate the big block motor. I have another fan shroud in the shop and will see if it will work, if not I will need to source a shroud for 4x4 big block or go with electric fans.
