  • Cooling System Renovation (Spal/Thermostat ?'s)

    Hey guys, recently I removed my aux fan and a/c. I'm planning on removing my mechanical fan as well and installing a spal unit. While I was removing my a/c, I noticed that my thermostat wasn't in the best condition and the wires to sensors in my thermostat were cut.

    Now for the spal fan, I plan on using this 16" slim one, which BeastMaster has confirmed fits in the stock shroud btw, but I'm wondering what to do about the wiring.

    I know some of you have used a wiring kit ( such as this one from fanman http://www.the-fan-man.com/shop/185fh-12-p-100.html ), but I don't exactly understand what you are getting with that kit. Does this wiring kit replace a sensor in the thermostat?

    Lastly, if I understand correctly, the thermostat has 2 sensors. The 3 pin sensor runs the aux fan, and the 2 pin is an a/c cutoff. Do I need the 2 pin sensor still since I don't have a/c? Can I just plug it? What do most guys without a/c do about it?

    Sorry for so many questions. Just trying to learn here.

    When I upgraded my VW to the dual 12" it was easier for me to use the SPAL Programmable Controller http://www.the-fan-man.com/shop/spal....html?cPath=30 than to tap all over in the stock sensors.

    Let me know how it works out, I want to do this upgrade myself but the 16" fan cfm is lower than the 14" High Performance fan... I wonder if we could get the 16" HP fan to fit?
    Rich!
