Is the truck tuned or stock? pulling 15,500 I see over 200 quite a bit. The only thing I have not done is add the Kodiak fan, Otherwise clean cooling stacks radiators flushed all new coolant and new Stats. I always run 5th gear locked Tow haul mode and a 30 HP tune from ATP, I have run it in modified stock and it can get warm there also.

Factory t-stats are 185-186. I don’t see dropping them 5-6 degrees making that big of a difference. If SENs truck is capable of doing exactly what he says it’s capable of doing, there are literally hundreds of thousands of people that are dying to know EXACTLY what his truck has done to it so they can mirror it in theirs. Myself included.

And the source of those constant 200* temps. The truck stock gauge is not known for accuracy.

My pickup has factory t-stats and i decided i'm going to replace them. I bought a pair of the COOL Mishi's b/c its a drop in the right direction without too much to hurt me in the winter months. I have no expectation I will notice a difference other than my idle temps being just above 174 instead of just above 180. Assuming these gauges work.

I tried testing them in a pot on the stove with a digital thermometer but they were barely opening at their set temps. Not too knowledgeable on them. Maybe they start cracking at the set temp and then fully open at a slightly higher temp? I dunno.

Good catch. I have a photo i've posted on here showing my CTS2 reading 181 and dash gauge reading 210.

Starting lower (earlier opening stats) will just make a vehicle run cooler when not loaded hard, in my experiences. If the cooling system(s) can’t keep up, they can’t keep up.

Anyone with a link to this Kodiak fan clutch? I swear I’ve read probably every forum thread on Duramax cooling issues and I’ve yet to see this particular brand mentioned.

sorry I made it sound like all you need is thermostats and a clutch and your good to go and that's not the case the truck is very moded I need to update my parts list I spent lots of time with a thermal imaging camera slowly picking off all the dumb stuff and when I did the stats and clutch it all came together

So then what are all your cooling mods? The only way to remove heat is by giveing it less BTU OR remove more than you put in quicker

If referring to mine my temps are read from my CTS
