Not doing a restoration. Just an infrequent driver.
Thanks,

I think for the money it's the way to go, the copper old school radiators can be iffy at keeping the engine cool, more so on an over bore engine. Go for it!

Going to pull mine this weekend, if the weather cooperates, and take it to the radiator guru for an assessment. I'm seeing prices in the $200-$250 range for the aluminum jobs.
HG, you know what brand your brother got? I'm leaning towards one from Monster Cooling, unless I get some guidance from the assembled. I figure an aluminum radiator will go well with my plastic gas tank.
Hey Hains, You should bring that flag I turned you on to to Pauls next month. Fun to watch peoples reaction when they "get it".

I'm running one on my truck and it has lasted for a few years now, not a ton of use on it but it cools really well and has no shroud, i did have to replace my water pump do to a leak and over heating but that was a worn water pump, after that even at 80F i was pushing under my operating temp.

I talked to a local radiator repair man (yes there are still a few). He also builds custom radiators for street rods, muscle cars, 4-wheelers, etc. He said that so many guys were buying aluminum radiators rather than pay him to recore or otherwise repair theirs, that he decided to get into the aluminum radiator business and sell them to those who wanted to go the cheap route, rather than watch them go down the street. He's sold a lot of them. Now he's starting to see them come back with cracks in the tanks, in the mounting brackets, around the necks, etc., and they cannot be fixed. So now he's building new radiators or recoring old copper radiators to replace the aluminum ones. BW

That's interesting, Bruce. First off, that's great that the old time radiator guy was smart enough to adapt his business model in order to stay in business. I've witnessed the need to change in other professions, and the staunch refusal to do so...and dollars fly by the door.
Anyways, back to the aluminum rads...did he say why the crack are irreparable?

Still fighting. Local shop wanted $800+ to rebuild mine. Shop 50 miles away wanted $500 for same.
Found a NOS rad for $450. S'posed to go look t'morrow. Two hour drive.
Film at 1100!
Ah-hem,

Not specifically, but I would think that perhaps, being aluminum, it cannot be soldered, and welding it would be like welding a pop can. This is strictly my thought, it could be wrong. I've been told by other shops that the aluminum radiators can't be repaired, but then, we're being told by some that copper radiators can't be fixed as well. BW

Now please take into consideration that I know next to nothing about welding and nothing about aluminum properties. But this thread has me interested! I found this: m.youtube.com/watch?v=bGGoD8OuvYMId be inclined to practice and then give it a go before spending a few hundred dollars. What do you guys with more experience think? |

Be Monday before I can make this happen.
The aluminum welding is spiffy. Didn't take that guy long to get his torch closer to his work, though.

you can weld aluminum the filler spout on mine is welded on, now if the tubes are broken then welding becomes tricky or impossible but soldier and other methods are do able, i do know a guy who can weld pop cans together I'm going to try after a while.

::)I run an aluminum radiator in my Tonka Jeep, seems to work well. The top of oem was plastic it started seeping. Thought I would try aluminum instead of another plastic topped one.

Schimmster, you can't solder aluminum. Healey Arc, spool gun, or epoxy. Oilly

Oilly Oh contraire wise man  , I seen with my own eye's at the Minnesota state fair years back, one of those snake oil welding demo's, the guy brazed two beer cans together with a propane torch. It can be done with the right magic rod, where one gets that, I do not know  . Aluminum radiators I think are as durable as any other, if they are cracking the mounting is flexing and needs to be corrected.........IMHO the downside is the inability to field repair easily, one can solder a toob in the field or pinch one off and get home with a copper core, not as easily done on aluminum.

Years ago, for the Hunters out there, A friend of mine and I fabricated quite the tree stand from aluminum L stock, and a Benz o Matic, and those magic rods. He was a bow hunter, and carried his stand into the woods. Aluminum is light. It actually worked very well. Here comes the drift...
I have some old Acid core 50 lead/50 Tin Oatey Soldier, that will stick to just about anything...
You cant buy it anymore, and it is illegal to use on plumbing now.
I use it for copper eavestrough, and leeder pipe repairs...

I once tried to solder, not braze, aluminum tubing into a brass junction block. Epic fail. Tin/lead solder will not stick to aluminum. The guy that brass welded aluminum cans together, now that coupled with different melting points would have been something to see. I'm pretty good at emptying aluminum cans. Oil |

Two like metals with magic flux no doubt. That would be good to have for aluminum radiators. Space age = $$$$$$ i'll bet. Oil

the guy at the flea market with aluminum brazing rods does show the principle, you can do several different kinds of brazing to aluminum to get it to bond. There are a lot of rods like that they are all different kinds, you can solder it they key is prep prep prep and more prep. you have to get a special flux so the oxide gets off and stays off. you can even acetylene weld it. It is also a special kind of solder, i prefer the kind that comes in squares that jewelers use not the kind that plumbers use that comes in a spool.

I remember the TV commercials for that wonder rod. Watched the TV guy patch up an aluminum canoe.
Our canoe was a former rental canoe on "rock bash creek." (OK I made that creek name up) But it was a grumman rental canoe covered in dents. It had a couple of probably tig welded gashes. I think it still leaked and boy did I want to try out that TV aluminum brazing rod on it!
