good morning my name is ***** ***** I will assist
190 is on the button for running. lowering it will make it not as efficient.
you can change the thermostats to 180. it may be hard finding them as not many manufacturers make them.
ok, I understand.
replace the thermostats and see what happens. if it runs too cool, it will code for coolant temp.
please dont forget to rate me as it is the only way I get paid for my efforts
