location of engine block coolant drain bolt???

I am in the process of draining the coolant on my 99 Honda Civic LX SOHC 1.6L. Does anyone know where the drain bolt is on the block (if there is one)?

Thanks.

It's on the exhaust side (front as the engine sits installed in the car) of the block near the transmission end. It's a large round plug the whole thing unscrews.
