Coming in your ears.
Mine always been easy to bleed, start cold and take out the rad plug and heater hose plug.
Fill the header tank VERY SLOWLY until coolant comes out of the rad plug.
Place rad plug back in hand tight and start. Rad level should drop, slowly add to header tank until decent bubble free comes out of rad. Plug without letting air in ideally.
Then time to let it warm up, replace header tank cap and heater hose cap but regularly bleed hose cap until bubble free comes out.
Should be reyt now
