Drain Cock for side of engine block

These drain cocks are designed to be permanently installed into the side of the engine block between the front and the middle freeze plug. They act as an open/close valve, and allow you to drain the coolant neatly and cleanly and make sure the blocks water jackets are fully drained if necessary. Another one of those super hard to find items that you really need for every quality build. Use two per engine, one on each side.
