The OEM setup for my motor has some convoluted coolant circuit, and I'm looking to rationalise it a bit.
Seems the stock setup has a pressurised header tank with inputs to it from at least 3 different parts of the coolant circuit- main outlet hose from the motor, return from the rad to the motor, and a branch off one of the heater hoses.
I'm not familiar with pressurised header tanks, my knowledge ends with a pressurised radiator cap and an overflow tank.
Is It all really necessary? I assume I need to run a header tank as an air trap at the highest point of the system? Any way around this to avoid needing a header tank?
If a header tank is really needed, do I really need so many inputs to it?
Cheers
