My Mag has been overheating and running hot. The head isn't blown, there are no leaks in hoses, and the fans work. I also did a radiator flush. There is definitely air in the system. Guess the next step is to check the water pump?

Also, some weird stuff:

I was turning my heater on while overheating, because apparently, that is supposed to help....so- today, the heater was blowing cold AC air! ....so that's weird.
