I saw the announcement about the FWC system from MMI, which got me thinking about my own system. I have an full flow system, but I am puzzled after looking at the diagrams as to how the raw water diverted to the engine block actually cools the block. There must be some sort of a pipe that traverses the block before emptying back into the thermostat, correct? The illustrations and explanations suggest to a novice like me that the raw water is just washing around somewhere inside the engine.
