Radiator without bleed valve

[dylan_diy]

Hello having moved house earlier this year I have noticed a problem. I have a small radiator in the third bedroom that has no bleed valve (the radiator is newer than all the rest in the house and has obviously been replaced at some point). The problem that I now have is that having drained the system when decorating, upon refilling the system (I have a header tank in the loft) I can bleed all the rads except the one in the third bedroom - subsequently it now has a big air pocket and no heat is coming out.

Any suggestions?? - I can I know just get another rad and have seen them for about £23

Look at behind the top of the rad, should be there probably covered with a plastic cap.
Should be able to feel slight bump with finger.
Remove and bleed
