follow the upper return hose to the housing/branch thing. It's inside of there. There is a bleed screw on it as well, and one next to the expansion (where you put coolant) tank on the rad.

the plastic screw on top of the radiator was constantley putting out steam when i opened it earlier and wasnt really slowing down neither, is my thermostat and bleed screw on the join from where the top pipe off the rad goes and the bottom pipe off the rad goes to, theres some sort of electrical connection there which is held on by a maybe m6 allan bolt, i undone it and it looked like it had some oil on it also there looks like a 10mm bolt with a crimped wire attached to it

Well, now you got me confused. Can you tell me which car you have, and I'll help you more ?

if you don't know the name of the engine a year is a helpful hint. or does your valve cover have plastic or is it all metal?

its a 520i E34 J reg

its a plastic screw on top of the radiator next to the filling bottle,

there's a cast join where the bottom pipe of the rad goes and the pipe from the top of the rad goes to, is this where the bleed screw is and the thermostat is, uve then got a pipe directly below the top one which is of smaller diameter and it looks like this goes towards the back somewhere, not sure what lump it is, m10 m20

Well, you car could be either M20 or M50, but here goes for both

M20:
1 - bleed screw
2 - thermostat housing and bleed screw on top of it.... you'll see it as it only screws in about half way... it sticks out.

I'll tell you where it is on the M50 (very likely the same), but I'll go check on my dad's 91 in a minute.

On the M50, the bleed screw on the radiator is in the same exact place. The one on the thermostat housing seems to be behind the place where the hoses come together, and I am assuming you have to pull that back to get to it...
