    The fan doesn't really draw much current.
    Just wired mine to the Blue/Red wire (SIG Circuit) and then through an On/Off switch.
    Tend to simply leave the switch on all the time.

    If you want to add something to it, a thermostatically controlled switch might be a better idea.
    Have it turn on whenever the temp is over say 180 degrees F.
    Napa should have these, would need an in-line hose tee adapter also.
    That way it takes care of itself, it simply turns on when needed, and off when not.

    Looking forward to seeing your pics! ;)!

    Rock :-o

    [​IMG] is what I ended up with with the shroud. its ok.. I could have done better IMO but its late in the season.. raining out.. im short tempered about the loss of what was a great snow pack. :o| Oh well its the nature of the beast right?

    Looking at my pick maybe I should take some time and clean up the old RX ! lol

    Also I put mine on a simple on/off switch as well. I thought about getting a temp sender but again.. being late in the season maybe that is a job for boring summer nights[/img]

    I mounted mine to the left on the dash.
    There is a nice flat, round area that worked great!

    You want a 2006-on, the fans & the radiators are all the same.

    The coolant shut-off to the carbs made a big difference on mine also!

    I have never had an over heating issue with my RX. But this would be great insurance!!

    The mounting tabs are thicker on some later model apex, vector (not sure of the years) but my buddies 06 apex rad broke right at the tabs, then the reverse linkage rubed a hole in the middle of it.

    tabs....

    If you can or know somone who can weld aluminum, you can save a lot of money buying a radiator with the tabs off already. I just made some new tabs out of diamond plate and they've been working great. I'll get a pic when i go back out to the shop.

    One piece of diamond plate and two holes. Then welded it all the way accross the front.

    First season with my '05 RX-1 is behind me and I'm really thinking of going this route before next season. Had a couple outings with little cooling going on so red light and snow got packed under my feet. Make much better with some additional cooling.

    Newbslice question that I think I already know the answer to. This Apex radiator simply replaces the stock RX1 radiator right, you aren't adding a 2nd radiator to the front right? I'm trying to be pro-active on my cooling before my sled has any overheating issues.
