    I use the dual winstar fans on my car. They cover the complete radiator and work well. Im going to install them on my Blazer. Fans

    The Mark-VIII single fan is also a good choice, pulls about 5000CFM but is pretty loud.

    - That looks hot /forums/images/graemlins/grin.gif

    Is that from 1windstar or 2
    And did you use a thermostat or toggle switch
    That must be a custom fan shroud
    I like it /forums/images/graemlins/thumb.gif

    That is a standard 1995 Ford Winstar fan setup.
    It is dual fans in the molded shroud.
    Took some slight trimming to make it fit but was pretty easy. Heres another link to the guy who turned me on to the setup Winstar Fans

    I have a thermal sensor in the block that kicks in at 205 and off at 185 (I run a 180 stat) I also have it wired to the A/C compressor so when the air is on, the fans turn on.
    I ran each fan thru a 50A relay but have them both come on at one time. Some have one fan running full time and the second one come on when needed.

    I have another set of fans in the garage, will probably install them this winter. The factory clutch fan is noisy as hell and feels like a big load on the engine.

    Also, I have heard of some folks using the smaller Taurus fan and mount it inside the factory shroud (against the radiator) and leave the stock fan insitu. They have a switch to turn on the electric fan when wheeling.

    The fans pull 30+ amps, make sure your alternator is up to the additional load.

    Theres another one or two pics of the fans on my car at This link.

    Just so you guys know, typically a mechanical fan has been known to pull more air than an electric. Your overheating is likely because of a plugged up radiator rather than a crappy fan.

    yeah but if your are wheeling and not pulling many RPMs how much air do you really think is moving? Vs. an electric that is just pulling full on air.

    Looks sweet! What kind of additional load is the alternator seeing with the fans? How much did you spend on the fan upgrade, not including a new alternator if you put one in? Thanks!

    Just depends how the fan was designed. It's a compromise of sorts, since the engine/ mechanical fan RPM is variable.

    That is a sick setup, that is a seemingly plentiful setup from a junk yard.
