I am wondering what folks use for the fresh water cooling circuit in their diesel engines: 1. Pure antifreeze, or 2. 50/50 mixtue of antifreeze/water, 3. other. Peter
50/50 provides the max protection from boil or freeze, why use anything different? This has always been the case with auto gas engines, now maybe my mind set should be differnt for a marine diesel, if so I would like to hear from an expert on this?? otherwise this has always been the mixture of choice.
I use 50/50, as advised by the small print on the antifreeze container. I also use the non-toxic "Sierra" brand, just in case the heating loop in the hot water tank ever leaks...
