i know, this is not stang tech, but it is tech ... i am trying to change the water pump on my mother in law's 1992 caprice classic wagon, and i have the fan bolts off, but i need to get the thing that the fan was bolted to off the front of the pump. it is that light colored thing with all the ridges in it. fyi, the water pump is that rusty thing behind the fan. or am i supposed to remove the pulley from the front of the pump and leave the fan connected to that thing? any chevy guys here?
