I am working on a friends 1910 touring his rad is nice brass wise but the core is plugged beyond repair can I buy just the core and if so should it be flat tube or round tube. I have looked up brass works but they only list complete rads Thanks Colin

I had my brass radiator recored. You can have round tubes if it's a show car or flat tubes for maximum efficiency. My car is for driving, so I chose flat.

Details are on this page: http://dauntlessgeezer.com/DG96.html.

Thanks Steve Its not a show car but not a driver either if I can buy a core I will do it myself. One of the T guys here had his 15 rad done here they did a great job right up until they pressure tested it and did all the soldering on the out side of the tank.

Colin, Why would a T radiator be pressure tested? They run at zero pressure unlike modern cars. So long as there is no leak, it is good.

John - Simple answer to your question is that nowadays, with nearly ALL radiator work being done on modern radiators, the accepted method is to pressure test, and they do that, because they ALWAYS do that and don't know that pressure testing is not to be done on Model T Ford radiators. And to tell them that when you drop the radiator off at the radiator repair shop is usually not sufficient. You have to make sure that the guy that actually does the work, "gets the word" not to pressure test. And that's not always easy.

In other words, they do it, because they always do it! Like even if I specify "no mustard" on my hamburger at the fast food joint, by the time the guy flipping burgers "assembles" my hamburger, it usually gets mustard anyway, because "that's the way he "ALWAYS" does it!

Have a brass tag made up and use a dab of silicone to stick it to the top tank. Tag should read This radiator SHALL NOT be pressure tested Due to resulting damage or injury. (Don't tell them the injury would be from you running him over with your T) then when the Job is done the silicone can be removed with a Q-tip and your wife's fingernail polish remover.

G.R. - Ha,ha,....kinda' like when going in for surgery, marking your arm or leg, etc, with felt-tip pen, which one to operate on, eh? Good idea! (:^) (:^)

All of the old timers that did good work back in the 60s are gone and the new ones coming up don't want to be bothered with the old stuff so I will do it myself Its not rocket science. I don't trust the shops here and I will not send it to the States in fear of it being lost it is the cars original rad,so I'm waiting for a reply from Brass works. Cheers Colin

G.R. , thats a great idea. Thats why I have a new core in mine because they dont understand english when you tell them DO NOT PRESSURISE THIS.

Although the cooling system isnt pressurised like "modern cars"
with a water pump and pressure radiator cap, there is still a certain amount of "Head pressure" caused by the weight of the water in our T's. All radiators (and fuel tanks for that matter) should be pressure tested to prove they are leak free. The trick is the pressure used should be extremely low (couple of PSI)
Just my thoughts. Alan

Alan,
Not just your thoughts, but is a fact.

Colin,

I have a flat tube Brassworks radiator that developed a leak. I called Brassworks to ask what they would charge to re-core it and they said it would be cheaper to buy a new one than to pay the labor to re-core it.

Dan

doing the re-core on a rad is not a problem get the right core is the problem.
