Has anyone had a problem with their temperature on their c350 mine seems to go to 90 then drops down to the center usually when I'm driving at a high speed. Is it normal ? Is my thermostat bad ? Should I go get it check out ?

What's normal?----If you are concerned, simply flush the system, replace the thermostat and add the correct mix of applicable fluids!
