Need to replace water pump (first time) but looks like I need some tools to remove the fan clutch? I know parts store must have these but does anyone know a good website that shows you pics on how to use the tools? It looks like one holds the water pump pulley and the other the big nut near fan clutch. Also the fan clutch kits I've seen on line to buy start with 1984 F150, wondering if they'll work on 1983?
