My parts book lists everything from 160/180/192/205° for the thermostat with no notes. Which one is it? Cleaning up my garage today I found a Stant 36309 195° thermo that I think I bought years ago for the 2020. Seems I read somewhere that the diesels like to run hotter than the gas. I think I've got a 175/180 in it now, at least that's what the temp gauge is showing when it warms up.

Last summer I poked a hole in the radiator, or rather the hydraulic pump coupling did when it came apart, and with the new radiator and new antifreeze, it doesn't leak any more (and I got rid of the 'leak stop') and the temp is more consistent. Radiator came from Turkey according to the package.

195°F thermostat will be fine
