Good Evening, Well just to follow up on the bimmer, I removed the radiator in order to get the fan off, man what a job! the bottom radiator hose clamp is surrounded by two electrical connections and the AC unit, then once its loose it won't slide out without you being a contortionist or with some help, which I did not have. Finnaly though it was out and I could remove the fan, well evrything I read on the" inter web" said the screw was reverse thread. Well I think that meant only the screw on clutches not the bolt on. A 1980 has 1 or the other. Anyway quess what? Yep, I broke the bolt off trying to loosen it by tightening it. Well thats where I stand, I am currently searching for a electric fan from a junk yard, I think I can make a ford taurus type work, I will let you know. Later all ......
