Help bleeding THIS radiator

[Naffa]

Hey there folks, idiotic student alert.

I have had a browse, and I can't find any information on how to bleed this particular radiator. All the others in this house just have slots, and you can bleed them with a key, but not so here.

The radiator looks exactly the same on the other side, I might add.

I can't get the grill at the top to come off. I can just give the landlord a call, but I'd much rather do it myself, as it's hopefully quite simple.

Thanks a bunch guys.

Ok, now I just have to acquire some mole grips.

THANKS!

Thanks guys, but the mole grips comment was a joke, hence the ''.

Of course a socket or spanner!
