Coolant drain plug?
 

I have a 1989 Accord EX...I want to drain out all my coolant, but I can't find the engine block drain plug. The repair guide I have only says that you have to "loosen the engine block drain bolt on the front side of the engine" but doesn't actually say where it is on the front of the engine [:@]

It's easier to just drain the radiator. But if you want, the engine drain plug is behind the right side of the exhuast manifold. 19mm plug.
