Radial Engine Cooling

[Shardur]

I was wondering if it will be possible in the future to remove cooling liquid leaks from planes with air cooled radial engines?

One of the major advantages of that kind of engine is that due to the fact that it is air cooled it cannot loose cooling liquids and therefore is much more resistant to enemy fire since it can't be "killed" by a bullet in the radiator. In RL a radial engine would often work after a cylinder has been shot out, but in game they quit just like inline engines.
