Its been about 105-110 here in Tucson the last few days. My truck with a stock tstat and efans will run around 180 on the Hway and 205 in stop and go traffic. Although Im not FI yet

In 95 degree weather mine doesnt go above 185 with at 160 stat and efans. It will actually run a couple degrees cooler with ac running due to both fans being on high

Well I've had it idling forever on a 90deg day to see what would happen and all seemed well.....just trying to minimize getting stranded/towed......maybe if I wired the efans to an on/off switch that would be a good added bit of insurance?

Spoolin, both really.

Do you have any problems with that stat in the winter months? Not trying to threadjack, I have just been curious about this.

Nope, because I park it in the garage when winter comes and it stays there till spring. I did run it in the winter years and years ago and had no issues, heat wasnt quite as hot but it was fine.

i would also like to add... the oil going through the turbo aint exactly cold when it drains back!... i would add a huge oil cooler if you live in a hotter state....

I am, My truck is doing the same thing and I can't figure it out. The set up is, 04 SSS, 34" rad, 05 efans, 05+ gm truck wiring harness, ran from the PCM with override controls in the cab for both fan 1 and 2. On days that are less than 90* she stays at 180, on 100*+ day she stays at 190-195. But when I go up any of the passes towards vegas or any other long pass, temp starts to go up fast. I try to keep it at 0 vac/boost while on the pass, and for the most part the truck maintains speeds. Usually 75-80mph. every now and then I will feed it 0-4psi to maintain speed. When this starts to happen, my trans also starts to heat up fast. reaching 200* when my normal trans operating temp is 160*. My intake temps stay in check...

I'm going to see if a 180* stat will help, currently I have a 160*. From there I am going to add an oil cooler line to the turbo return line and see if that helps. I know that my radiator is not plugged and that my water pump is working fine.

On my last trip to vegas last week, I manually turned on the fans on the way back, and that seemed to make the problem worse... as the temp got higher.

Once I am at the summit of the pass, the temps (both engine and trans) drop down almost instantly...
