Hey so when I'm driving my engine temperature likes to sit at 102-3 and idle at 105-7 it just seems a little high. I know it's not a major problem and bmw like to run hot but I read that normal gas engines run at near 96. I'm just wondering if there is anything I can do to bring the temperature down to normal. Should I replace the coolant or do a coolant flush? Is there something I can replace on the radiator? Really anything to get that temperature into normal range?
