So far so good, installation was easy - thermostat works great. Monitoring the temp, i see that it may get as high as 210 occasionally but the thermostat is regulating the temp about 197 to 203...

Using it in my 2nd Gen

I went from the Cummins OEM 190 to this. This fluctuates much more than the OEM 190 did. Nothing gradual about this thermostat opening. I do appreciate the heater working quicker but prefer the engine maintain a more steady temp and not fluctuate so much to be honest.
