so today i drained the coolant but only from the radiator and filled with new OEM coolant. About 1.5gallon came out. It was very simple. but i was told that there is another drain plug for the engine. now i haven't looked but i think i will leave it.

The other drain plug is on the back of the motor below the exhaust ports for cyl #2/3. Its brass, sticks out about 2"' has a hose barb on it if you are so inclined. Turn it counterclockwise and it will drain the head and the cooling jacket of the block

I wondered what that thing was.

Thanks for the tip.
