The Car is a Mini one Cabriolet 2005.
It has had a new thermostat, radiator cap and two changes of antifreeze but problems still persist.
It overheated ages ago so the above was done. It had been fine for a while until today.
The expansion tank is full to the brim of antifreeze and is slowly coming down whilst the engine is cooling.
I heard a bubbling noise from inside the car; presumably noise from the expansion tank or heater.
My thinking is an air lock somewhere but I'm not sure.
Any help greatly appreciated.
