What temperature thermostat do you use?

[Policeboss]

The reason for the question is this..The 2013-2014 Ram 3500 6.7L Cummins trucks have an extra radiator and the failure prone Y pipe in the hoses. I’m looking to replace some coolant parts and plan to open the system thinking of replacing the thermostat and have found 180,190,200 degree options.

If you still have the aftertreatment you need to leave the thermostat alone. It could cause aftertreatment issues.
