Coolant radiator refilling procedure

[Welshy_Pete]

I seen the bleed one on the heater matrix I didn't know there was on the thermostat.

So empty radiator then flush out with hose pipe. 

Then run engine with heaters on full power hot and refill coolant but with both bleed open once both starting coming out the system clear of air?

How many liters water then antifreeze needed for both?

Thanks
