Ok so I thought I'd get this thread started a little early to get some input from people more knowledgeable in the diesel world.

Objective:
Convert a 6.0l Powerstroke over to waterless coolant. Increase coolant operating temperature and fan on set point.

Known solutions/issues:
Several people are already running Evans with no issues.
Fan on set point can be modified in your custom tune to make use of your high temp coolant.
High temp thermostat is not available to my knowledge.

Proposed solution:
I was thinking of modifying a stock thermostat to incorporate a low profile linear solenoid. The problem with this however is where do we get the trigger from. I was thinking if we wire it into the fan circuit with a resistor/capacitor pair on the lead to the fan. This would be used to delay it by a set period. As a result a thermostat with an adjustable set point would be created.

Feel free to weigh in. I'm still trying to organize my thoughts on this one and have definitely not considered all possibilities / ramifications.

I've been thinking of switching to Evans+ for some time now. IMO I think it's worth a try. I wouldn't go away from the stock thermostat setup while it may look good on paper why put in something that you have no long term reliability info on? The stock thermostat is super reliable so basically "If it ain't broke don't fix it."

I'd be interested in trying a 205* thermostat if one existed for our trucks that failed open like the current motocraft ones. Unfortunately, there is none available to my knowledge. I wouldnt want it to be electronically controlled though, thats just asking for failure imo

I would not trust an electronically contolled t-stat

JMO tho

I think just raising the fan-on point would be good enough usually, however, using air conditioning seems to override the fan setting, and makes it come on no matter what temperature it is. I know that down here in Texas, where it's been over 100 degrees for 2 months straight, my fan is on constantly, even with coolant temperatures in the 190's. I'm pretty sure it's because my AC is always on max.

If we could just find a 205-210* thermostat that fits our trucks, and is reliable, that would be the easiest way.

quick question what do you gain from running higher coolant temps?

Supposedly you gain efficiency. I don't think it will really affect that much, but I'd be willing to be the test dummy to see for sure XD

The likely hood of finding one unless we can get an aftermarket company to make one are slim. That was why I was thinking of an electric thermostat. If we use it to determine the optimal temperature it would be stronger ammunition to get one tested and put into production. I'll probably fiddle around with the idea more after I get all the Mods on my truck.

Also it is to bad about the AC/Fan tie in. If we re-engineered the ac system as a heat pump we could use the coolant as a base temp and run the system off of that. We would get heat in the winter and could get cool air in the summer. The calcs wouldn't be hard but finding a compressor to match probably won't be easy.
