Well I drained the green stuff and flushed it 6 times with fresh water, which seemed like a lot. The first couple times I forgot to turn on the heat though. Now, though, I've managed to lose the block bolt washer gasket in the engine compartment because I dropped the whole bolt when taking it out. Solutions?
