    What are normal Coolant temps?

    Through the torque app, I see the temps anywhere from 195F to 210F. Maybe higher in warmer weather. The higher temps are often within city driving.
    I have a 2015 sxt with 65k km. Gonna change the coolant this summer along with the brake fluid.

    Never checked but I say about right. The thermostat opens 82C +/- 1.5 degrees C, 180F, and with a 18# cap along with 50/50 coolant/antifreeze it won't boil until @ 267F.
    Good idea to change both.
