I need to replace an old automotive radiator in an open air pusher configuration with a 912S engine. The easiest way would be to install a Rotax #995699 radiator. This radiator is designed for the two cycle engines and it's cooling area is 20% larger than the 912 radiator. It also requires no header tank. The only drawback I can see is that the inlet and outlet sizes on this radiator are 19mm. rather than the 25mm. outlets on the 912 radiator. Will this restriction be a problem?

    Hi Bill,

    Good question and I don't personally know of anyone that could help. usually Rotax has a reason for what they do and they have about 4 million flight hours to back it up.
