    I don't know Jerry, I'm just tryin' to think out of the box.....
    Pretty sure mine has three coolant temp sensors, all "transducers", no "switches". One at the front of a head for dedicated input to the EFI PCM, one on the thermostat neck that's the dedicated input to the SPAL programmable fan controller, and one on the intake that feeds my dash indicator. I set the trigger points on the fans by watching the PCM temp readout, which is hottest, and I know that my dash indicator shows the average coolant temp, about 15F below the head outlet.

    Zippi, I hope you got your engine ID figured out, since that's the question you brought.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
