    Default Electric fan help

    Okay I'm trying to set up a Taurus fan as a pusher. Keep in mind this is a temp fix. The picture shows the best way to mount. However, mounting this direction has the air flow going toward the front of the Jeep instead of back through the radiator and engine.

    My question: Can I reverse the fan direction?
    If so how?
    Can I flip the wires without burning the fan up?

    There are currently 3 wires:
    Brown w/yellow strip = high speed
    Brown w/orange strip = low speed
    Black = ground

    I'm not sure about the Taurus fan specifically, but on most you flip the blades over and reverse the direction. Also, most of the time, you can wire the fan motor backwards without hurting it. You will just reduce the effectiveness.

    The Taurus fan is too big. What you need is the double fan from a Contour (V6). That's what I run on my CJ7. Reversing the direction is as simple as reversing the power wires.

    Like I said this is a temp fix. I got the taurus fan for free. I tried flipping the Br w/O wire as ground and it seemed to work okay. Obviously not as effeciently because of blade contours but it works. There is no way to turn the fan around as the blades are plastic and molded as part of the casing for the motor.

    Okay, it will work reversed. This is what I have:

    Br w/O as = Gnd
    Black = low speed
    Br w/Y = high speed

    It is probably not as efficient as it would be if the fan was turning the correct way, but it will hold a piece of cardboard to it at high speed.

    Remember, I still have my engine fan and this is a temporary solution as I might be pulling the carbed 305 out for TBI 350 this winter.

    I was going to wire this direct to battery and to a hi/off/lo switch. I was going to put a fuse on the power line from battery. Is that okay or do I really need a relay. If so how should I wire it in and what kind of relay?
