    Well here it is XRU. My version of an Electronic Fan Mod write up. I did videos through my adventure........

    Cost:

    Fan from junk yard- $40
    Thermostat fan kit- $24 (Auto Zone)
    misc wiring, brackets- $30

    Total time: 6 hours



    Got to start with a good breakfast. MY daughter Mykala (11) said "daddy.....you have to eat a good breakfast first!!"...so I had to eat:

    The thermostat fan kit I got from Auto Zone:

    The fan I bought from a junk yard....."guess you don't have to know how to spell to work at a junk yard...:laugh::

    Testing the right fan first:

    Testing the left fan next:

    Got the fan wiring ready. Used the black wire for the ground and the green wire for power:

    Broke the radiator overflow resevoir. Ended up buying a universal one from Auto Zone. Mounted it next to the air intake box:

    Removed the fan from the pulley. Came off pretty easy. Then removed the fan housing:

    OOOPS...the worst mess up so far. Didn't put the bolts back on the water pump pully....end result......slung the S-blet off and lost the pully for a little while :biggrin:
    http://s272.photobucket.com/albums/jj196/lexusyota2005/?action=view&current=holdcrapWTF.flv


    The pre-fit.....Notice the sound of the waterpump pully fallin off......:laugh:

    http://s272.photobucket.com/albums/jj196/lexusyota2005/?action=view&current=holdcrapWTF.flv


    Test fit.....trying to figure out how to mount it up. Made some brackets out of sheet metal pre made bracket strips:

    Is the wiring right. We nearly re-wired the entire set up before Carlos (MancheX) realized he didn't wire the ground to the relay......he must take the blame for this one......

    All done!! Final product: http://s272.photobucket.com/albums/jj196/lexusyota2005/?action=view&current=finallydone.flv

    Oh, finally found a place I liked to put my URD sticker. Sorry URD......its just too big to put anywhere else.....I like it here......

    Well thats my write up folks. Let me know if you have any questions......:top:

    oh. Side note: The thermostat was bad in the kit I bought from Auto Zone... Don't know why. We solved it by wiring the thermostat wire to the accessory wire. Now when the key turns on...the fan turns on. When I turn it off...it goes off. Ill take the thermostat back to auto zone in time....but for now....it works.

    Nice job! Yea i forgot to hook up the ground wire...but in my defense, it was due to miss communication LOL. It was fun though, can't wait to do this to mine.

    One I broke the stock one.
    Its actually molded in to the housing around the fan (mounted to the radiator). I was going to try to get it out of the housing..........till I broke it.....:biggrin:.

    Im sure you can take it out......but I had issues with it. Doesn't really matter though..only spent 9 dollars on it....form Auto Zone.

    From you of course.......:biggrin:

    Not really more power, just feels like there is less drag on the engine. I did notice it reves quicker/ pops off the line quicker.

    There is not a huge noticable difference. Just knowing you are taking drag of the motor was enough for me. There are a few members here that have done this mod too. Maybe that can give some more info.....

    You could always take a trip to El Paso, TX.....

    From a junkyard sorry should have been more specific. I want to make it look as stock as possible. And for a decent price don't want to cost a couple limbs.

    Resurrection of an old thread!

    Which one is the accessory wire? Is it inside the fuse box?

    Trying to wire up my electric fan set up so that it turns off when the key turns off.

    It's directly to the battery right now and comes on when it's up to temp.

    Problem is, even when the truck is off the fan runs and runs until it's cool enough. In this heat lately, it's killing my battery...

    You don't want accessory power, you want ignition. Make sure you use a relay, grab an ignition powered circuit under the hood, use it to trigger the relay to pull power directly from the battery. Also if you don't have it tied into your ac, you'll want to do that as well or you won't have ac when sitting still and the fan isn't running.

    My set up has a relay. It uses a temp probe inserted into the radiator. And it is powered directly off the battery. I can adjust what temp it comes on.

    I'd like to just have it come on when the key is on. Just like the post in this thread. Just not sure exactly how to do it.

    You say to 'grab' an ignition circuit. I know what you mean. Just don't know how you mean

    Thanks for your help so far
