That method will be fine. That is what I do. The engine block drain is hard to get to and they are many times really stuck in there. I would hate to snap that off!97hb said:Didn't use the block drains. I just drained the radiator, filled back up. Ran with the heater on for a couple hours, then drained radiator again and refilled. I think as long as I do it every 30k I should be good.
