FW coolant side drain Westerbeke 8KW
I hate to admit it, but it's been so long since I changed the FW coolant in my Westerbeke, I can't remember how I drained it. There is a petcock on the underside of the heat exchanger, but that's for raw water. Is there a drain, or do I have to remove one of the coolant hoses to the heat exchanger? This is a 1986 model that came with my Krogen.
