I thought the 2015s were in one of the exterior rear view mirrors and they moved it to behind the grille for 2016. I could be wrong about that. The 2016s are definitely behind the grille.
My 2018 has it under the passenger mirror. MUCH better location IMO, since it doesn't heat up with the engine when truck is parked. And MUCH easier to replace if needed too .
Switch was made in 2018. ‘15-17 in grill, ‘18-up in bottom of mirror.
I thought I had read something about that. Just had the years backwards. Wonder why the move. As stated before, they have been behind the grille (in front of radiator) for many years.

My 2015 runs the low speed fan often enough that truck's heat appears to have no affect on the temperature reading. Temp doesn't change during the warm-up period, and doesn't change once I get moving.
