Hello all, We have a Yanmar 3JH2E, and I would like to drain and flush the cooling system, including the hot water heater before I move the boat. I see in the engine manual talk about small petcocks, but is there a way, such as by removing hoses that I can not just drain the coolant, but actually flush through fresh water? I'm thinking there's got to be a relatively simple approach, but I could be wrong..
Thanks in advance! Bruce Whitmore (847) 404-5092 (mobile) [email protected]
