Thanks to mreid and oldsouth ...
Old South ... while I do have an 8mm hex head on a socket, I don't have enough room between the radiator and the waterpump shaft to get the socket and wrench in there ... my clutch has only three 10mm bolts holding the fan to it ... removing these three will get the fan off the clutch, but won't get the clutch off the waterpump shaft will it?
Would prefer not to remove radiator as I just change coolant ... but, will if I have to. I guess I could also grind the hex head socket down a bit ....
oldsouth ... any more advice?
