Guys,

I have read countless threads about how simply installing a lower temp thermostat will not lower your overall operating temp. Before installing the 170 degree thermostat from Roe my temp gauge would climb past middle to around 210/215. After installing the 170 and bleeding the system it sits at around 180 degrees now regardless of sitting in traffic, heat outside, etc. I don’t know if I had air bubbles in the system prior or what but the temp sits more comfortably for me now. I always drove with one eye on the road and one eye on the temp but not any more. Truck is completely stock besides the thermostat. Just trying to help anyone contemplating a 170/180 degree thermostat install. It certainly solved my issues.

I have one installed, and it still runs around 198-205. I've bled the system a few times, had to replace the radiator recently, no change. I'm told that I need to have a tune by Torrie to tell the computer to turn the fan on at the lower temp. Odd how you didn't have to do that.
 
Right on. I had read the same thing. The fan mod was next on the list if the thermostat change alone didn’t work. I’m wondering if it was a combination of a faulty stock thermostat and also air in the system. I can’t see how a 170 install alone would bring it down that much but for whatever reason it did. It was to the point where I started wondering if there were head gasket issues with regards to the heat level but that doesn’t seem to be the case.

I can’t explain it then other than maybe the stock thermostat was faulty combined with air in the system. Truck runs steady 180 degrees now.

Thanks guys.
 
We do not know your location. So, ambient conditions combined with your preexisting conditions before the thermostat change may not reveal comparative results.

One thing for sure, your engine at 180 deg. is NOT in the optimal operating range. The designed 190-200 deg. range insures proper combustion pressure to provide the wide range of thrust this engine can produce. Not to mention the ability to burn off acids. INTAKE air temperature and a tune that LEANS out the stock fuel curve is KEY. The stock CAI with a high flow aftermarket filter works best.

Good Luck with the RC!

Cheers!

My 10 runs at 210-220 at times but the big fan and radiator keeps an eye on it. My experience with the SRT's i have owned, they all run hot.
