Send pic. thank you.No, get an FSM! On the lower part of your front cylinder there is an Allen head. Make sure you locate the right one. I can send a pic if you need. That is the engine drain plug. You have to drain the engine and the radiator. However, the radiator only holds a small amount, so you can just easily drain the engine once a year and you’ll be fine. The radiator drain plug is difficult to get off and if you snap it...good luck. And they do snap!
