    I was wondering if anyone could tell me what fan switch they used for electric fans? I have mine relayed and switched already so I am looking for a temp switch for the intake. Has anyone just picked one from another car at autozone that would screw into the intake next to the thermostat?

    I bought a temp switch that connect at 180*F from painless. wired it up to a relay and when the switch connect it turns the relay on and then it turns the fan on.

    I also have a Painless unit. Turns on at 200, off around 185. Works great.

    If you want an easy to find parts-store part, get one for a 3rdgen Camaro or Firebird with a V8. They turn on at something like 220 and off at about 210, but they still work just fine.

    I got one that actives at 180* cause here in Texas the heat can be pretty high. Rather have the fan running then letting the motor get too high. But up North this might not be too big of a problem

    I do not need the painless set up. I have wired in a nissan relay box to the low and high speed fans to my arch controller. I want to put a temp switch inline to the low speed fan in the manifold and was wondering if anyone has done the same? If so what temp switch did you use and can I just pick one up at an auto parts store?

    From the third gen boys:

    Here is some information on the various cooling fan switches made by GP Sorenson that should screw right in. At least the pitures on the advance auto parts and napa site look like it. Hope this helps someone.

    Part Number Closing Temperature
    FS1............................222-238
    FS3............................240-252
    FS4............................211-227
    FS6............................204-220

    Also, put the switch in the head for a quicker turn on if needed.

    Don't use the temp relay from Summit/Jegs. I've burned two into the 'permanently on' position within 5 minutes of the car warming up.

    I couldn't get "FS" to cross over. Is it safe to assume that a BWD brand TFS1 is the same as a GP FS1?
