what causes f/i setups to overheat?
#13
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.

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...
