There was a service bulletin on leaks, had my 2015 repaired under warranty for leaks.  In short faulty thermostat cause radiator failure.

Diyer02 that is true,  saved 1 more shipping operation though haha. 

 

 

Maybe I should have called the dealer first to see if this would all have been taken care of for free even though I'm out of warranty?

 

Eh whatever all seems good now and I have a new tstat  arriving tomorrow.   I'm in this for about $410 now including tstat, radiator,  coolant. 

 

If dealer would have covered me I guess that would have been nice because if something goes wrong again in a couple months maybe it would have been their problem instead of mine? Who knows. 

 

End of the day it was a good experience for me and I have learned a lot.

On a 6 Year old truck if your going to the trouble to drain the coolant it's easiest to just change everything:

Belts

Hoses

Water pump

Thermostat

 

Then it should be good for another 5 or 6.

Final update:

So did the radiator install and also put a new thermostat in. 

 

Got around 100 or so miles so far and no leaks from what I can tell.  

 

I notice a difference in temp gauge. It now stays steady at just a hair under 210, no matter the driving conditions... idling with AC on,  highway, city, etc.   With the original tstat it was always kind of moving around, never stayed in one place for too long of a time.
