Electric Cooling Fan Temp Settings

[rilesnpsd]

Hello all,
Couldn’t find this info anywhere…

Had some maintenance done to the Yukon and the tuner at the shop tweaked the factory fan set points. Why? I don’t know.

It never has ran hot and always kicked on the fans as needed (if warm out and or running the AC).

Does any one know the factory on and off temp set points for both fan one and fan 2?

The fans are running entirely way too often without the AC on and it’s not that hot here in San Diego. Temp gauge doesn’t get above 210 mark since the fans kick on before it can even get up to temp.

Thanks for your help!

Tuning, Diagnostics, Electronics, and Wiring - efan programming - I have a 2003 Chevy Suburban. I pulled the efans and harness out of a 05 silverado. I pinned the green wire to pin 42 on the blue ecm plug and the blue wire to pin 33 of the green ecm plug. I have a diablo intune so I had someone...

I’ve also grabbed a couple stock BIN files and examined as well. IIRC, those line up to that image. Mine are set lower but haven’t found them to run in excess, yet. Fan 1 on at 205*.

I live in California and def want (and have) my fans coming on sooner, it's way too freaking hot here, makes the ac work better

I’m definitely ok with them coming on slightly sooner, but when the actual engine temp is 205 and the fans are on power ranger mode, it’s too much.
What do you have your at Wes?
