High coolant temps

I have a 06 6.0l, 89000 miles. Within the last two months I have rebuilt my turbo, for a smoking issue, while in there, I went ahead and replaced my oil cooler. I have sent my Ficm to Ed for repair. My truck has a 4" turbo back exhaust, sct programmer, run it on tow, when I sent in the Ficm I had the atlas program installed. I also put in the blue sping for the fuel pressure issues. I run 5w40 mobile one synthitic w/2 bottles of rev-x every oil change.Saying all that, since I put the Ficm back in I have been getting high coolant temps on the highway, towing or not. Running around town my temps stay at 188 to 194. On the highway it will run around 194 until I get to a grade and then it will go to 220 sometimes up to 235. When I did the turbo and oil cooler I spent a week flushing the cooling system. Anyone have any ideals what I could check? Please help. Thanks

Have you checked the temperatures of the ECT and Eot after sitting for awhile, are they close to each other? This would verify that your sensors are accurate.

Yes, they are within 2-3 deg of one another.

Your temps should never be below the themostat opening temp of 190 to 195 after warm up. You prrobably have a stuck open themostat which will cause your temp readings to be a little off. Your delta may not be as high as it seems.

Check the air flow thru the a/c condensor; cac and radiator. Check for cooling fan operation. The entire cooling system has to work properly together to keep the temps in normal ranges.

Just put a new thermostat in it, thought that might be it. As for not dropping below 192, every time it jumps up to 220-230 it goes down to 178-180. Kinda freaky I know. Just driving me crazy!

subscribed...I want to know how this one turns out. Mine has done similar things, I put in a new thermostat and it seems to have helped some, but still does weird things.

Do you still have your EGR valve? If you don't the issue may be the PCM controlling the fan clutch as with some flash versions there is a problem reaching maximum engagement of the fan clutch if the EGR valve is not still electrically connected.

might be the case...my egr is deleted, but the connection is still in place. my temps just rise more than they should before settling out. they will go up to 215-220 and then rapidly fall back to 185-187 and then slowly get back to the 190 range and stay there like it's supposed to????? blows my mind..............

Is it possible your cooling system is a little low due to the small hose to the degas bottle from the center of the block kinked or plugged as to not let gas pockets in the top of your engine to reach the degas bottle? The fitting on the block side isn't very big. Do you find that your heater does not put out much at times untill you hit higher RPM's?
