Traveled the Ajo AZ desert this weekend ( 400+ miles) and collected pre-install data prior to installing coolant kit last night.
Kit went in well - no leaks. Tight install.
Will travel desert again this weekend and collect post install data.
I expect coolant temps to stay out of the 200+ range ( for this time of year- different story during July-August ) and tranny temps to trend to the lower side as well - we'll see.

I collect relative Speed/RPM's/isspro gauge readings from EGT, Tranny temp, Coolant temp, ambient outside temperature and border patrol attitude.
I will report back. That is all.
So here's the report..............................
A few more points. I'm running an intercooler, a/c condensor, ( big time air flow nasties ) 1 ton axles and aluminum radiator. These, along with the 3.73 yukons and additional gear weight added to this truck can have positive or negative effects upon engine heat. Bottom line for me is I saw greater heat last weekend without this new fangled coolant device than I saw this week with the device.
I drive in the desert. Anything that reduces engine heat is a keeper. I will be keeping the device on the truck. I don't care if it's blue, yellow, black, desert tan, purple, red or a combination of all colors as long as the truck makes it home, on its own, and in one piece, along with me.
Y'all can decide for yourselves. It's your equipment.
BTW,,,some of my contractor buds have sand box HMMV's with a similar device installed.
