Well you cant tell on the radiator actually. The reservior is seperate from the radiator itself, and the reservior has the cap on it. Its FULL. I actually need to remove some. It would seem the thing is full, and working right cuz it never overheats. So i dont think it has air, but possibly i guess.
I felt the hoses, seemed to be full of water. I dono, if you have seen the 96 or similar continentals its kind of a weird set up.
Pretty sure its not the thermostat, i never removed it. And it doesnt overheat.
