Nope-don't make sense at all---the one in the water pump will just be whatever comes out of radiator and not necessary---

Hmmmm, what if the sensor in the water pump switch is set to fire the fan(s) at 150 (190 at the heads)
I don't know Jerry, I'm just tryin' to think out of the box....

Yup. The one for the electric fans is by the water pump and one for the gauge on the dash is in the intake. It has to reach 180 I believe before the electric fan will come on which is almost never. No PS or PB to add to the load on the engine. Nice cool running engine.

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.

Yeah, I'd like to know too....

My 37 is currently in to have all the upholstery redone. I'll have to wait to check the numbers when I get it back in late May. To far away to go look. Ok guys I'm listening, where would be the optimal place to put the sender for the dash gage and the electric fan?
