Hi All,

When draining my radiator for a service last night, i tore out the bottom drain whilst only putting the slightest pressure on the drain bolt. I think the connection may have been passing for a little while.

Is this a worthwhile repair? Should i attempt myself and braze or get a pro?

Note the condition.

id take it to a shop. they will pressure test it. there are probably other small weeps on it.
I took mine to an old established radiator shop and for about $100 they made it like new.

as did i, for about the same money even.
it's a dying trade. i don't think any new vehicles come new with solid brass rads anymore.
 
Thank you guys. I live in a very remote part of Aus so radiator repairs are a send away (pay an arm or leg for postage) and wait 4 weeks ordeal.
This may however be the best way forward, however:
Any ideas (or good existing threads?) on the best way to braze/weld/solder/plug and/or tap???

I don't think they do either--can't fix 'em - just replace--(plastic,cheap junk) If you can find a good rad shop-definitely do that--My local one charged me $80 to clean and rod it out--you can't be that with a stick--BTW--I gave them $100, just because they did a good job)
 
Good Man Buffalo40 - i felt your pain whilst reading that thread as we both made the same mistake

Thanks again!
 
If it were me I would just solder it back together. In your case if you have to deal with shipping no matter what approach that you take, I would ust order a new one. That's ust if your solder doesn't hold up.
 
Thats a pretty easy repair by the looks of it. I would braze it back together and call it good. If its not leaking from anywhere else and you haven't had overheating issues then theres no point getting it refurbished , especially if you have to ship it somewhere.
 
yep i'll give it a red hot crack. (haha - get it!)

The rad isnt leaking elsewhere and holds pressure so i'll see how i go. The problem is where we live there isn't another town for 600km and any direction, so i like to have peace of mind with my repairs.

Wish me luck and Merry Christmas
 
Presumably you will make sure the drain is free and working smoothly before brazing the fitting back into place. Curiously I had my radiator recored a few months ago and when I removed it I noticed it didn't have a drain, never did. There is a hole in the surround that would have allowed access, but there had never been anything in the radiator. So I suppose another option for you would be to just braze a patch over the hole.
 
Thanks again guys
Grabbed some solder and flux the other day, as well as a welding tip for my oxy/acet so will clean and try tonight (weather dependant)

I have freed the smaller drain bolt that extends into the plug extension. Have a healthy dose of hydrophobic anti-seize ready to go on prior to reinstall
 
Update on the repair - well I think i was successfull. Have to pressure test the rad tonight however it's holding water at present.

When i pulled out the plug originally, i must have kinked the copper a little. The solder was running down onto the cores!!!

Second attempt and a little less heat seems to have done the trick. Anyone know of an easy way to pressure test a radiator?
 
Thanks brian

I was going to find something cylindrical, insert into the open rad hose and clamp the rad hoses onto that. This should block the inlet/outlet ends enough to hold pressure. Then i'll install the cap and clamp an air line into the overflow hose. I was going to fill (prob only 4/5ths) the tank with water and apply air pressure through the over-flow. Just need to find something to block the hoses...
