    Fan clutch alternatives?

    Anyone ever swap their fan clutch out for an electric setup or some other alternative?

    The engine driven fan and clutch can be replaced with an electric fan. I'm of the opinion that to do so you need a 16" fan rated for at least 1800cfm. You also need to control the fan with an 82-83C thermoswitch and 30a relay. The hardest part of this is coming up with a mount for the fan that doesn't involve the radiator core. Anything that directly attaches to the radiator core can wear a hole in the radiator. Done properly, replacement of the engine driven fan winds up costing more that a brand new engine driven fan and clutch, so it isn't cheap solution for a bad fan or clutch.
    The car makes it possible, but the driver makes it happen.
