Slant Six Forum :: Flux source?

Whachootalkinbout?

D/W

Any place that sells soldering supplies... Most likely local place, radioshack, hardware stores, Mail order - digikey, jameco, mouser.

Yes, you can buy liquid flux at those places as well. Maybe not in the quantity you need but it is sold in liquid form for electronics as well.

I googled "radiator flux" and turned up plenty of hits but they all seem like OEM's selling to shops only.

Item # 7598838188 on ebay is a 16oz jar labled as "Regular Paste Flux - Used in HVAC, Heat Exchangers, Plumbing, Wave Soldering, Roofing, Stained Glass, Radiator Repair and more "

Any place that sells soldering supplies... Most likely local place, radioshack, hardware stores, or electronic supply places. Make sure it says anti-corrosive on it, because what you may find, esp at hardware store, is likely made for soldering copper pipe and is a lot more agressive (and corrosive...)

Mail order - digikey, jameco, mouser.

The material used in most radiators that came in slant six cars is pretty close to copper pipe anyway. I wouldn't hesitate to use plumbing flux on one.

"make sure it says anti-corrosive" warning is only applicable to electrics.

I'm not a radiator expert but if it'll corrode copper on a circuit board it'll corrode copper on a radiator right?

What was that place.... eastwood, they sell leading supplies for bodywork, they may have flux there as well.

Luthastro - on the ebay auction I mentioned, I believe the container had the manufacturers website on it that offerd various sizes and types of flux.

Anybody know how to get hold of some (no gallons needed) radiator flux?

I know and have known for many years where to buy the various kinds of solder - often self-fluxed like rosin core or acid core or a coating - and several kinds of flux that I have used as a plumber, radio technician and computer tinkerer. My dad made his own flux by disolving zinc in acid. I realize there are more different kinds of flux than there kinds of solder, but radiator flux is a different animal what you get from Ace for copper pipe (and the solder is different too). Every radiator man I've watched used a liquid, sloshing it on with a little mop, out of a quart or gallon can. That doesn't prove they all do, of course. Maybe there are some radiator men here?

I've use the plumbing flux (greasy looking stuff with a brush) and plumbing solder on a few radiators......

May want to try that route as some may sell in small amounts, or perhaps stumble upon a diy radiator shop.

Quote: I googled "radiator flux" and turned up plenty of hits but they all seem like OEM's selling to shops only. Which is why I was asking here. I found it in gallons, five gallons, as much as a barrel. Quote: Item # 7598838188 on ebay is a 16oz jar labled as "Regular Paste Flux - Used in HVAC, Heat Exchangers, Plumbing, Wave Soldering, Roofing, Stained Glass, Radiator Repair and more " I guess I could try it even though I don't trust sales talk for 2 seconds. I've been had way too many times. Right now I'm haggling with a guy who advertised a Plymouth manual CD on eBay - half inch letters saying "PLYMOUTH 1964 1965 1966." He sent me a general CD that barely mentions Plymouth and he refuses to replace it except at more cost. As soon as the 10 day waiting period is up I'm filing a complaint. Thanks.

The two are not the same thing, and the "make sure it says anti-corrosive" warning is only applicable to electrics.

Mine has copper fins but brass (where the leak is) tubes. I've had several different kinds of flux in a lifetime of repairing all kinds of things as a business and I've never gotten any of them to solder all that well on brass. I figure flux made especially for radiators does 'em both easily. And I mean easily. When you see how fast some of these guys flash a spot there's no way it can be a half right flux. Huge torch. Slop the spot with flux, hit it with stick solder and heat, dunk it to find the next bubble source - all in about 3 or 4 seconds.

Antifreeze protects against corrosion but I still wouldn't solder my radiator with soemthing I knew was corrosive....

You can clean and wash a radiator after you solder it. Can't do that with circuit boards...........
