Way cool...

Although the cylinder barrels on a Rotax 912 engine are air cooled, its cylinder heads are cooled by liquid antifreeze passing through a radiator, much like an automobile engine. And because the engine block, cylinder barrels and heads are all aluminum and expand and contract at the same rate, there is hardly a chance of shock cooling the engine. 80 hp or 100 hp, your choice.
