MBA Marine Posted November 21, 2012 Share Posted November 21, 2012 Oh great oracles, I seek your knowledge. Having trawled google (other search engines are available) I have conflicting options so here it goes. On this old ford watermota direct raw water cooled (pre crossflow 1.5ish), where is best to tap out for a calorifier? On an perkins I have used a plug just after thermostat and returned to the suction side of the raw water pump, this worked well, get the water to a good temp but doesn't overheat the engine. But after web searches people say different things, including the method i have used before, tapping out before thermostat and using a circulation pump! Its not my boat and is in the next week getting lifted and trailed away to its new owner, so i do not have time for trial and error methods, Water a bit below ideal temp i could live with but a cannot have a overheating engine. I have pics but the will not upload as they are too big, I have know idea how to reduce there size! Quote Link to comment Share on other sites More sharing options...
