water pump pulley question
Boy sure are a lot of posts for a simple solution. Put it back to stock. Proper type fans blade, proper fan clutch, proper shroud, Thermostat, radiator cap, change to a recovery system overflow like all modern cars. Should have no problems. Fans only do work below 40-45 mph after that they are just a drag on your engine. Momentum forces more air thru the radiator than the fan can.
