So I was looking for a hotter thermostat to put in the truck to get it up to temp better, around 190 at least.

Under the 1997 pickup listings, nothing over 180 is available

On a 1990, you can get a 195 degree, whats the deal with this???

Same engines, is it for the smog requirements???(NOx is created by heat)
