Diesel Companion

Don't remove the water pump impeller. Change the impeller when you recommission, or you may loose some of the water/antifreeze mix. If you have an indirect cooling system, it's not a bad idea to flush the sea water part as above, but the thermostat doesn't have to be open - that's in the freshwater. Sea water remaining in the system could freeze in very low temperatures and draining the system isn't always fully effective. AIR SYSTEM Disconnect the exhaust hose from the engine and check its condition. Remove air cleaner(s) from the engine. Spray water repellent oil up exhaust and air intakes and then seal with plastic bags to prevent damp air entering. ELECTRICS The battery needs to be recharged monthly so take it home if necessary. ANODES As well as any anodes in the cooling system, it's essential that sail drive anodes are checked.Manley, Pat is the author of 'Diesel Companion' with ISBN 9781898660910 and ISBN 1898660913.
