Sweet thanks for the advise il give it a go and let you guys know how it goes

Quick update, Iv not yet had time to try and bleed it but I have noticed today that the heaters do get warm but go cold and it keeps changing temperature... I'm hoping that is a sign of an air lock and nothing more haha

Turns out my cooling system needed about an extra 2 litres it was that air locked! All sorted now after a good bleed
