For my Westerbeke, which is also a pain to drain, my mechanic suggested installing a valve in the lower heat exchanger hose and, once annually, drain what will come out and add new stuff. He said I will not get all the antifreeze out doing it this way, but if I do it annually it won’t matter.

It appears to be soft brass because it the head was already damaged by someone trying to remove it before I tried to get a wrench on it. I was unable to budge it even after leaving PB Blaster on it for a few days. I am afraid to do much more because I am not sure I can find a replacement if I damage it more. The only other thing I can think of to do is to remove one of the hoses from the heat exchanger and turn the engine on long enough to pump the antifreeze out. The alternative is to just start filling the overflow with new antifreeze and have it slowly exchange over time. Any suggestions?

The drain plug in the photo I have from the manual is near the dip stick on the side of the engine I can reach but can’t see. The photo in the manual is pretty useless as I can’t see what it is pointing to. Does anyone know more precisely what it looks like (size?) or a way to find it by feel (or another way to drain)?
