I know I really ought to take the side branch off & poke out between the bores - I'm still not totally sure that the flow restriction is the radiator, it could be the block, but every time I take the side branch off an engine that new to me I have to drill out & re-tap the studs which is a painful & fiddly job. This side branch looks awful, but it is (currently) watertight....
It looks like it's worth a go then - I think I'll take the rad off so I can agitate it. I may also try and get hold of some bulk Sodium Bicarb to neutralise the brick cleaner.
I do live in a hard water area, so depending on the holes, I may try that, or I may look at touching up with a soldering iron or small torch - or is that a recipe for disaster?
