Engine coolant drain plug.

When changing out the engine coolant you need to open the drain plug in the engine block. It is situated under the exhaust manifold towards the rear of the block. (The hex head of the plug on my engine is 22mm.) The plug uses a copper washer to maintain a good seal.

I wonder how many radiator places do that? Good info mate.
