2003 C3 cooling system bleeds

[Shaun]

Morning all, I replaced my radiator yesterday in my 2003 C3 and I’m a bit worried I haven’t got all the air out of the system. Can anybody tell me where the bleed screws are on this please?

On the second picture would it be the large plug on the top of the pipe before it goes into the engine block? I believe there should be 2 but I’m a little clueless with these sort of things.

Thanks in advance.

Shaun.
