Interior heating problem

Hello, i have Renault Laguna II 2005 1.9 DCI and I got some weird issue after main belt service. When engine is at working temps (90c), i heard weird bubling noise ant 1,2 - 1,4k RPM (sounds like air in cooling system), and also i have no heat from blower untill i put heater at max temps. Only cold or max heat...
So maybe i can get here a full tutorial how to bleed cooling system for my F9Q674 engine?
Thanks in advance !

take expansion cap off, start engine, as soon as you see the temp gauge move, switch engine off, walk away for 1/2 hour ,check coolant level , if ok refit cap go give it a run and see if thats cured it
