Why Such A Hot Thermostat?

[nanook12]

Put a 190F on with a metal housing. Don’t understand why they want such a hot thermostat in the 3.0?
runs great 30 degrees cooler!

Without the expense of custom tunes etc?

Emissions/efficiency.

Then secondarily, high enough temperatures to adequately cook moisture out of the oil.

Every single internal combustion engine ever runs better and more efficiently when it's hotter.

It's not 1991, putting some silly cool 160 degree t stat in your TBI Camaro so the PCM dumps fuel isn't a power gain today, it's just wasting money.

This right here!

There are no emissions left on this 23 JTRD.
Moisture starts vaporizing around 180F, this is a 190 thermostat.

I don't think Jeep was worried about the deleted ones, lol.
