    Default Block drain plug left side of engine is a puzzle

    I'm wondering why this drain plug has a hose running from it, looks like a 1/4" braided hose much like the fuel lines, runs from the plug to a spigot on the bottom of the rad tank, this is an ISEKI 17 hp 3 cyl. diesel (G-174) I'm wishing to use this as a return from a circlating block heater I,m tryin' to install, the manual states nothing except that this plug is a block drain on the left side of the engine block if it has a purpose other than just a way of draining the cyl. block, if not I may have to install a "Y"connection and keeping it original, or can I just cap off the spigot on the lower rad tank, and use it only as a return to the cyl. block for my block heater....Thanks AMPA
