Just had a guy put a temp gauge and a new sending unit on a 2500. Seems to run right at 210 degrees. How do I know if this is correct temp and if the gauge and sending unit are correct to start with?
If it is running at 210 degrees, that is high. I would check into it and see why. I had a YM2000 that was running very warm. I had to get my radiator rodded out and the problem was fixed.
