Fellow Sailors. My water heater gave up the ghost last week. It started leaking from unknown places. I ordered a new one and this will be a good time to change out the engine coolant. My water heater is in a lazarette at cockpit level which is well above the engine. I have heard horror stories about trying to get the air out of the water heater circuit. Is there a trick I should know? I have a bleeder valve at the entrance to the WH in the lazarette. Picture below. After filling the engine I am thinking I should pre load the WH with coolant as best as possible and then close the circuit. Then run the engine and open the bleeder valve and add coolant to engine fill. bleed and fill, bleed and fill, repeat until there is no more air. Is it that simple? Am I over thinking this? As always all wisdom and kind guidance is greatly appreciated.
