I have 1984 ODay 28, that I just purchased this past summer. It has a M3-20 Universal diesel engine. Can anyone tell me if I need to remove a thermostat in the raw water cooling side in order to circulate anti-freeze thru the system
to winterize it? If so, where is it located? Is is better to run the engine, pulling
the anti-freeze thru the raw water pump with the intake hose placed in a bucket or can it be pumped thru with a small piston pump?
