No way this thing was coming out easily. I snapped off the A/C pipe running across the top of the radiator, bent the radiator frame, removed the fan's wiring harness and was able to get it loose from the radiator. There is a BF pipe that is bolted to the forward engine head that carried coolant. Super sturdy thing and I didn't have a pry bar. I worked at it with the big screwdriver I had - nuthin'. I even stood on the thing and it held me up. Its fasteners were rusty too so no removing it. The fan came up but there wasn't enough room to angle it out between the radiator frame and this coolant pipe.
I already had a fan I bought off the shelf of a local boneyard but this one was in better shape. I did grab the harness so I guess I have what I need but I might go back and give that one another go.
Any preference between DCC's 2sp and FK-50P?
