Lost engine block drain plug!
Hah so I finally got that sucker off to drain the coolant from the engine block Into a bucket, and when I looked into the bucket afterwards only the crush washer was there!

I think the pressure of the coolant propelled my drain plug into the under body of the war somewhere! I couldn't it find it on the ground anywhere. I searched but couldnt find anything. I remember there was post similar to this where the person located where it was lodged/resting in their car. Does anyone remember or know?

Also, can I reuse the crush washer? And also where are there o rings in the cooling system? I'm replacing my radiator and lower radiator hose. Do I have to worry about o rings?

My drain plug has fallen and landed on top of the motor mount arm. You might get away with reusing the crush washer but they are like $0.20 so you might as well replace it. The o-rings are all part of the hoses so you can really only replace them if you replace the hoses.

check your motor mount or the....top of your control arm

It's a crush washer. Meant to be replaced not reused. It works as a gasket to prevent fluid leaks so I'd replace it with a new one.
