Raptors are closed loop cooling, the engine has full time antifreeze in the block and heads just like an automotive application.

Closed loop cooling requires a separate raw water cooling loop that uses lake water and a heat exchanger to cool the engine.

Winterizing a closed loop engine application is draining this raw water loop only.
