Brum Radiator Leak

[Russell]

I have a ’58 Birmingham Scott which has developed a slight radiator leak, am I okay to use a radiator sealant such as Radweld to try and seal it?

Thanks
Russell

There are better ones I believe, someone else will know what they are, I can’t remember just now.

I would say no to using a sealant because the core has only very fine spaces for the water to flow through, perhaps not as fine as in the earlier ‘honeycomb’ core radiators, but still needing care. A couple of years ago local section member Len Zitman gave me a can of a radiator sealant that claims to not restrict water flow within the core. It might be worth a try… It is called CT1 Miracle Seal, and it is made by C-Tec NI Ltd., in Northern Ireland. http://www.ct1ltd.com

this is reputed to be a very good product, obtainable at most motor parts stores:

K-Seal Coolant Leak Repair

Interestingly, Suzuki recommend the inclusion of Bars Leak in with the antifreeze for my RG500 with conventional cored radiator. I never bothered but after an engine rebuild I had an antifreeze leak but only when very hot. After much head scratching I tracked it down to a leak between the crankcase faces. With nothing to lose I tried the Bars Leak and it cured it and avoided me having to strip the engine again. Ten years later and a couple of antifreeze changes (without Bars Leak) it is still fine. I’m not saying it would work in a Scott or restrict cooling a little but would certainly be worth considering for a non-honeycomb rad?

I have successfully used K-Seal in a leaky film type Scott radiator with excellent results &
without any apparent side effects. I do flush the radiator ahead of the annual winter lay up
before refilling with fresh K-Seal for the new season. Works for me. Buy in on eBay.

I’ve tried some Miracle Seal and fingers crossed it seems to have done the trick, thanks for all the advice 🙂

I spoke too soon, it’s still seaping, can anyone recommend someone to do a repair ?

Graham Moag. Its just the cost of postage to and from that makes it a bit expensive…but then the bikes no good without a rad!

[Russell]

I’ve tried emailing Graham with no reply, does anyone know if he’s changed his email address?

[chris wastell]

He could be away on holiday this time of year?

[Stan Thomas]

I successfully emailed Graham only recently – so he hasn’t “done a runner”, and as Chris says, he’s probably on holiday or whatever. Graham has always been a very obliging chap, and undoubtedly will come back to you once he picks up your email.

I had a leaky rad on my 47/48 Squirrel that Graham suggested should be replaced.
The rad showed that it was supplied by Northern Radiators Limited of Leeds (contact@radiator-repair.co.uk)
When I contacted them they suggested I send them the rad for a quotation.
In the meantime I ‘found’ Bryan & Son in Tunbridge Wells, 01892 544635, closer to where I live on the south coast.
When I visited him with the rad he was building a new rad for a Bugatti!
2 hours and £70 later I had a repaired rad.
Dave Bushell, the Club’s librarian, has also used him.
Good luck.
Frank

Thanks, I’m near Leeds so I might try Northern Radiators, has anyone else used them ?

[Russell]

Northern Radiators have said it will need a new core, which will be in the order of £600, which may also damage the chrome, so it may need re chroming. I’ve no idea how/if I could source another one, and whether that would be cheaper, can anyone help?
