    Nissan Quest Electric fan conversion - alternative to taurus or ebay...

    Hey,
    After my mech fan died in 4' of water...and my first electric fan (16" procomp 3000cfm) fell off and got chewed up by the belts, i went today to Standards auto wreckers and managed to find a Nissan Quest electric fan - it's pretty big at 18" across, the shroud had to be trimmed a lot, and i had to remove the plastic motor cover and shave the bolts that keep the old fan pulley on to get it to fit (there's about 1/2" of clearance between the back of the fan and the pulley but it works great! I think it's better than the procomp because it has a shroud AND it's bigger, and i was unable to find 18" aftermarket fans...

    It has two speeds, and i'd say the high speed is MUCH stronger than my 3000cfm 16" fan... honestly feels like an mechanical fan when the clutch is fully engaged. I wired it up only using the high speed and also installed a switch inside

    just thought i'd post this as an alternative to the taurus fan or ebay...

    oh some details...good point!

    Ok a first Gen Nissan Quest or Mercury Villager. The one i took it from was pretty basic, so i would image this is the standard fan. It was simple to take out - literally 2 bolts and a few clips.

    The trimming was the hardest part...
    - trim away the fan's plastic motor cover
    - shave down the old fan bolts (i don't think you have remove it because it's the water pump)
    - I basically trimmed the shroud so that it did not have the factory flanges or tabs, by doing this i was able to sandwich the fan shroud between a piece my old shroud that i kept to mount the over flow tank in... the shroud also had to be trimmed at the top and the bottom, the fan is basically as bit of the rad, so it takes some playing around with to get it in..

    Here are some pics.

    I just took the jeep out and i noticed that with the fan running, in stop and go traffic (not like downtown T.O., but stopping at every light) it cooled the jeep down to 73C which is where my thermostat turns off... it might be over kill for daily driver use but it'll be awesome on the trails!

    Hmm... looks good! Thanks As for overkill, I'm sure if you wired up the low speed to your automatic, and high speed on manual (or second thermal switch) you'd have all the control you need and quieter too.

    Noltz...that makes complete sense lol Seriously why didn't i think of that lol. or even change it seasonally lol

    If i applied power to both the low and high speed...would it just stay on high?

    No, you would smoke the fan...right quick like...it has happened to more than a few Taurus fans when people think they have a brilliant idea...the thought process is usually as follows

    hmmmm...

    - if it goes x on low speed
    - and goes y on high speed
    - then x+y should = Z!!!
    - wire it up
    - flick the switch
    - works great (they don't realize that it isn't going any faster than y)
    - off they go driving
    - hmmm...that's odd, temp is rising...
    - hmmm...what's that steam coming out of my hood?
    - Jeep seems to be losing power...
    - oh shit, temp spiked, overheated...
    - WTF HAPPENED!?!?!?!

    They soon realize that x+y=engine gets too hot because fan says "**** you, I don't spin faster than Y, BITCH!"





    SO...YES, it will only stay on high...until it dies...



    PS. Thanks for the details and pics...subscribed for later use.
