Hi everybody.
The other nearly no wind day when cruising on my Bavaria 38C with a 2005 VOLVO PENTA MD2030D diesel engine I got an overheat warning and shut it down immediately. I found the coolant expansian tank empty and added 4.5l of coolant which strangely enough dissappeared completely without leaving any visible trace. I took me hours to return to the marina on sail only. Then I refilled the expansion tank once again, restarted the engine for a few minutes to enter my berth and it ran smoothly. I suspected, dismounted and checked the fresh/sea water heat exchanger but found no leaks. The other theoretical possibility would be a deficient head gasket, but there is no water in the oil, and a loss of more than 4.5l (1 gallon) of coolant in a few minutes seems a lot to me. Before starting any serious and possibly costly repairs, has anyone any idea where all this coolant has gone...???
Thanks for your attention.
