As you all are aware i was able to finally get my hands on a used engine thats in the can, i notice a few weeks ago while looking it over the drain cock on the right side and decided to open it, clear water ran out, well tonite were supposed to have temps in the 20's and well i went ahead and opened the drain cock to drain the water, i know these engines are heavy and thick but did i do the smart thing or would it have been okay to have left it alone, if you have a direct answer just send me a pm as im sort of worried, i know now that it won't freeze in the engine but i was curious if i did the right thing or if was worried for nothing.
