Today I winterized the 220DA I just bought, and removed the two upper blue plastic petcocks. I was able to loosen the port side lower brass petcock, and drained quite a bit of fluid from it. When I attempted to loosen and drain the starboard side lower petcock it wouldn't budge. I didn't want to force it for fear of breaking it off in the block. Is draining one side sufficient? I filled the engine with pink AF, so I'm thinking it should be ok. Any thoughts?
