Blimey! What kind of dart would make a hole in a rad unles it was already rusting out from the inside?

Any dart would, they are only thin steel.

Better a hole in the rad than this poor bugger.

Very easy to replace the rad Sandra.
Buy a rad of the same size, some PTFE and follow the instructions. You will most likely need a rad key, (large allen key). ;)
 
thanks
though doesn't need doing straight away as won't having heating on hopefully over the summer
 
If you drain the rad and sandpaper the surrounding paint back to shiny steel and then use epoxy to glue a cleaned 2p coin then it will usually repair the leak. Never touch either surface after they have been cleaned.

But that is a bodge repair and not what I would recommend but if done properly will usually work. BUT it could always start to leak again at any time later.

As others have said its quite possible that your rads are seriously corroded from the inside and ready to form leaking pinholes on their own.

I would have a great desire to pull the dart out of that boys head!

Similar 'bodge' to Agile's - clean area back to the metal, screw a self-tapping screw into the hole in the rad. then cover the lot in an epoxy repair putty, something like 'Devcon Plastic Steel'.

Beware if you have a therostatic valve on the rad. If the temperature drops, the valve may start to open and let some water into the radiator.
 
A better repair would be to braze or silver solder but that would be far easier if the rad was removed and laid to be horizontal.

That also needs soldering equipment and some skill.
