Not the point. The point is factory mis-design. Seems to be the norm. Stuff that works right is in the minority. The point is engine coolant temperature. The point is hose construction materials have not changed. The point is high temperatures eat hoses, engine mounted and engine compartment SENSORS and especially underhood batteries.
100F automatic transmission fluid is a perfect temperature. This means bypassing the radiator altogether. I would YANK that OEM thermostat and replace it with a 194F - 200F thermostat in a heartbeat.
I recommended this be done on several of my friend's vehicles. Oooooooo subsequent emissions certifications revealed no increase of the Big 5 pollutants. Numbers do not lie.
With automobiles in very cold winter climates, a 210-215 degree thermostat DOES reduce emissions especially for moderately long driving spells. Use the rig to commute or run to the 7-11 for a six-pack in sub freezing temps? A cooler thermostat may not be appropriate. Go to your new car dealer and see if the parts department offers a different thermostat for a heavy duty engine model and one for a half ton model. They don't? Neither do assembly lines.
