I don't remember if I had to take the radiator off or not. The only thing that I remember being odd though were adjusting screws on the pulley for the fan blade. I can't remember if were one or two or three where the bolt head was inside, between the pulley and the water pump, and the nuts and lock washers were outside of the pulley. Those adjusting bolts moved the fan blade closer to the radiator, or away from the radiator towards the engine. They were old, and I kind of remember one breaking, so I ended up replacing two or three, however many there were.
Hood has to come off. Radiator though? I can't remember.
Overall, was pretty simple. Again, onlu oddity was the adjusters of the fan blade that mounted to the pulley.
