The 532 to 582 saga continues. My cooling system for the 532 did not look like this. The coolant expansion tank connects between point 4 and the radiator instead of point 7 and the radiator. First of all does anyone see any issue with this implementation? I really don't want to have to rebuild a cooling system for it. Second of all, with the coolant expansion tank being directly connected to the water pump housing and the line to the overflow tank being above the water pump (it is the highest point in the system) do I even need to install a vent line from the water pump? The 532 did not have one.
