I have an extra 226 for my 49 Traveler, I have not fired it, my question is, does the engine have a tube like the old chevy and packard for the cooling going back to the last two cylinders? I don't want to attach a garden hose up and fire it and foul the back two cylinders with water if the tube, if there is one, is bad. Everything else I own runs and I haven't thought about this issue until I was aked about it. Thanks, the reason of the question was the water pump was froze up with corrosion, and couldn't answer my neighbors question.
