Reply to "351C Engine parts-detailed plan"

I am guilty of cheating because I completely modified the Cooling system so that it actually WORKS compared to the way it was designed in Modena (occupational hazard) I cancelled the swirl Tank and used the Collector Tank as an expansion Tank with Air in the top and Coolant in the half bottom. On the Tube that sits on top of the Thermostat I welded a Stud that connects with the top of the expansion Tank and allows potential Air to escape the system and collect in top of Expansion Tank. At the Bottom of the Tank I welded 2 Studs, one that connect to the suction side of Water Pump and the other connect the return line from the Heater Core. This way the Engine is self bleeding. The Tube exiting from the Thermostat goes uninterrupted to the Radiator (no swirl Tank etc) On the 1/4" Stud under the pressure Cap I connected a traditional collector (plastic) reservoir which is mounted low on the Frame behind the Firewall. (thinking of moving it to a place behind the right rear Wheel to minimize risk of spilling in from of Tyre, but so far not an issue)

This is close to how modern engine cooling systems are designed. Never had an issue with overheating btw.

on a note: any cooling system with Air pockets or trapped Air will potentially overheat as an Air Pocket prevents fluid circulation (just as on your central heating at home)
