I will be getting my repaired and cleaned radiator back this afternoon. I have been gathering parts to put the cooling system back together. I am installing a Hayden 687 plate type trans cooler to take a little load off the rad. I also want to add a fan clutch. The parts manuals list the pulley and spacer as being identical. I already have the 7 blade A/C fan on the car. I got an ACDelco 15-80250 clutch. There seem to be problems with the Hayden HD clutch and the ACDelco unit comes highly recommended. The FSM has no specifics or pics on this install.....has anyone done this sort of thing?
