What temp is relay one and two set to come on and off at. I had my PCM mail tuned for now and am not sure what the settings are. I have my relays wireed up from the PCM control and ran the engine up to 215 and got no power to my fans before I shut it off. Is it higher?

I don't remember the stock settings, but, 190*F & 200*F aren't a bad idea. Even if stock is/were 215*F is, I'd lower it. Usually, stock thermostats & cooling fans are set-up higher in order to meet emmissions regulations. BTW, your oil temps are usually 20 to 25*F higher than the coolant. So my fans are based on optimum "universal standard" oil viscocity temp of 100*C or 212*F. This is the temp where most oils are designed to run. So, basically 190* ish is a good low fan on temp unless the car sees WOT road course pulls or 10-15 hard pulls on a drag strip track night.

If I recall right, the stock temp that the PCM will turn on the fans is on at 226 and Off at 219 for #1 and for #2, on at 234 and off at 227?

With AC turned on, both fans should turn on..

I was thinking it was up there. Nothing is AC enabled now (wiring wise), so that should matter.

Thanks

Guess I'll pull the sensor and see if I can put it in a pot and hot plate to see if I'm wired good.

Mine is on at 210 degrees, will pull the temp down to 180 degrees before it shuts the fan down. It has been working very well for a long time. Of course with the A/C on it's a different story.
