Thanks

Its so much work to remove that plug. How i do it is do drain radiator, refill with water and flush with a hose.


Run engine for a couple of minutes to circulate



Then drain radiator again, leave plug open and run engine for a minute with bottom hose off.


Then refill with fresh coolant. You will not get in the full amount, but it will be sufficient.


Stupid place to put a drain point.
