Fixing a broken bleed valve on a radiator
John Clancy
Does anyone have any suggestions as to the best way to fix a radiator
with a broken bleed valve - the small square bolt head has snapped off
and I'd obviously prefer not to have to replace the radiator for that.
Can the shaft of the bolt be drilled out and replaced?

without much difficulty. I assume that it was broken whilst
over-tightening it, trying to stop it weeping.
If the seating has been damaged or distorted, a replacement one may need
some form of thread sealing, in order to prevent leaking. That may have
to be replaced every time the radiator is bled. PTFE tape may be enough.

==================================
If your radiator has a removable bleed valve (type which can be removed
completely - usually located on outer end of radiator) then this tool will
enable you remove it even if the small bleed screw is broken or seized:

Note the square end with a small circular hole. There are other similar
tools available which don't have this square end / circular hole which
won't do this job so check before buying.
Obviously, you will have to drain or lock the radiator before doing the
job.

That should work, but a lot of radiators usually have the bleed screw in a
seperate housing. ie a blakig plate at one end a a fitting to take the bleed
screw at the other. It may be possible to replace the housing.
As for replacement, when my friend lost his bleed screw we could not find
one to match in the wholesalers but we found one at the dumpit site.

Hi,
Thanks for the help guys - I have ordered the radiator spanner from
Screwfix (as well as a set of screw extractors just in case) and will
let you know how I get on after they have arrived.
