M50B25 engine cooling modifications
Shown are two options I've come up with for modifying the cooling system on the M50 engine. Both involve cutting the heater and throttle body valves out of the loop. The first assumes just following the existing plumbing and the second blanking those outlets from the engine off completely which would be the tidier option.
I'll need to add a coolant header tank in but this needs to be the highest point in the system so mounted on the battery box seems the obvious place. I had planned to stick the battery in the back of the car anyway to save room up the front.
I'm working from the assumption that when the engine reaches temperature, the thermostat opens and allows hot water into the top of the radiator. In this case it will also allow any excess due to expansion back to the header tank via a much more constricted pipe therefore ensuring the bulk flows through the rad and gets cooled
