I just pulled my 160* tstat for a stock tstat and i need to reprogram my fan 1 and 2 on/off temps. Does anyone have these available? i can't find my original tune. i would like the stock on/off temps for both fans.

Thanks

 

My 2006 Avalanche 5.3 Stock Settings were:

Fan 1 On: 226
Fan 1 Off: 219

Fan 2 On: 235
Fan 2 Off: 227

Not sure if Silverado is different but surely its in the ballpark.

cheers

Awesome! Thanks, Guys

Huge Help

 

holly crap those are some high temps.... Are you planning on commanding them on at cooler temp thresholds?

 

I have a 160° t'stat, the motor will run as cool as 170° +-. If I set the fans at 185°, my ECT will run at 185°, or 190°, or whatever the off temperature is. Something to consider.

 

That does seem awful high and its funny because on stock vehicles the fans seem to kick on right around the 210-215 mark according to the gauge. I had mine set to turn on at 204 and off at 198 on low and turn on high at 206 and off at 201. I would rather run the risk of running the fans a little sooner, possibly even a little more often than let the engine get up near 230 to the point it looses a lot of power and takes a lot longer to cool down. I don't have efans yet but I had the fan settings turned on for when I do get them.
