i was coming up one of the hills where the rocks roll out from under you and there is a ledge to climb over but with out gears i just don't have the power to crawl it, so I had to bounce over it then i'm guessing the flex in the driveline mounts and fan shroud got the water pump pulley just close enough to knock the fans engine cap off and spill its guts ooh well, it was at the end of the trail so wasn't too bad jpfp pulled me a bit then i wired the a/c fan up and blasted the heater till we got to the paved road with help in between when it started to get warm then all was well drove home. I think i may have tossed out my old fan clutch gotta look in the yard in the when i get up if i did checker has one instock so i'll pick it up then drop the rad down which doesn't look hard.
