Rad leaking from top

[willing amateur]

first thought it was from bleed valve and tightened it - it snapped off but realised it was the outer part leaking looks like corroding also

Tightened that and still leaking

can I take it out and replace ?

rather than drain down can I use freeze pac on pipes ?

how do I tell if I have sealed system ?


so many questions and so little time !!!!!!

You can turn off the rad from the valves on either side at the bottom, now with an old towel to hand remove the offending bleed nipple, a little amount of water will come out at this point.

now nip down to Diy shed and get a replacement pop it in, do not overtighten as this distorts the rubber seal. Now open the rad valves the same number of turns it took to close them and bleed any air.
