Up here in Canada a 180F is a summer stat and 190F is a winter stat. Why would you want the engine hotter in summer, states side?
Curious
the thermostat doesnt set the engine temperature...only sets the level when it opens the circulation of the coolant....if the radiator isnt big enough , it wont matter what temp the stat opens..its going to run hot anyway...I had to finally replace my radiator to a alum 3 core to get it to run 190-200 in summers...it always ran 205-215 before....in the winter I prefer a warmer running engine anyway...not much difference on 180 and 190 , but cooler engine wears quicker
