Long since lost count of the times I've bled the Cooling System of Air from K-Series MG and Rover Engines.
There has to be a better way .... and there is as I discovered recently by trial and error.
I used my trusty Funnel and length of garden hose which for years enabled me to effectively fill the PG1 Gearboxes with little lubricant losses. This set up works well. :~
With that in mind and using a shorter length of garden hose with a Coolant Hose Off-Cut placed on the end. This locates over the 8mm Bleed Bolt Hole location on the metal coolant tube above the bell housing providing and effective seal.
Then, holding the funnel a shade higher above the Coolant Expansion Bottle with the garden hose located over the bleed bolt location ~ 8mm Bleed Bolt removed of course ~ pour coolant in until it rises and reaches the MAX Index in the Expansion Bottle. Then, immediately remove the hose from the Bleed Bolt location and quickly replace the 8mm Bolt. It works remarkably well. Just be patient adding a little coolant to the Funnel each time until correct level is reached.
Done this to three 1.8T K-Series ZT-T engines now. Wish I'd sussed out this speedy method years ago. This is the simple Funnel and short piece of Garden Hose arrangement. You may need to find a rubber hose ( old piece of coolant hose Off-Cut of suitable dimensions is what I used ) to fit on the end of the garden hose for some bleed bolt locations as the size varies from car to car. As it happens, the Garden Hose off cut alone fitted over it without the need for the rubber hose off cut on one car. :~
Here it is in place at end of topping up bleeding process. :~
