Did nothing to the truck but spent some time on the computer trying to find out what a correct fan for the motor looks like,I have a 49-54 car fan on it and there is only 1/4 inch between the fan and radiator. If I would have to change a fan belt on the road I would be screwed as I do not think I could get one on,I do not think I can remove the fan without taking the water pump off with it so it might have to get changed when I install another 235 in it.
