I hope this doesnt sound to stupid, but I wonder how to fill the coolant system in my RV-12 iS. I have the built manual and the maintanance manual. It reads kind of "just fill it". But would that not trap air in the radiator, since both inlet and outlet are on the bottom side? Then there is the radiator plug. A good place to remove the trapped air. But the built manual reads install the plug using pipe thread sealant. So I think the plugs stays in. What am I missing?
