I know this has been asked before but ...
I want to bleed the radiator but can't figure out how to undo the bleed screw! The knowledge base refers to "a plug with a cross shaped depression for a screwdriver to undo it", but mine has a plug with a deep hole in the centre with (using a torch) some sort of depression at the bottom but impossible to tell what to use. I'm being very cautious because I don't want to break anything.
There's a reference in the k.b. to another article with photos of the bleed points but I couldn't find that.
