46highboypu Sunsetdart,
I hope that the repair goes well but any way I'll still have some rad shop tank it and see if it is indeed repaired. By the way I'm envious of your wagon I LOVE it!

Thanks again!!

sunsetdart I know you know where the leak is at. I would go one step further and pressure test it in a tank of water. You plug all the holes and put a fitting in one of them to couple an airline. You don't want to use very high pressure, just enough to fill the rad with air and under water, you will spot the leak. At least this way you can actually pinpoint the problem.

46highboypu Hey guys, thanks for the input but...the hole seems to be up under the top tank in the core. The shop couldn't get to it to solder or what ever so they tried to stuff epoxy into the fins to seal the leak. Which worked for awhile. Against popular advice I even tried the aluminum stop leak, which worked for awhile. Now I'm tired of the "fixes" and want to repair the leak. I have talked to lots of people who seem the think it would be a radical way to go to cut the top off but if it leaks and can't be repaired then there is no loss. It's junk any way. The new radiator cost me $400 and the cheapest one I've found is $260, I can get a lot of welding done for $200 or so. When I have my garage project done and can get to the hot rod I think this is the plan I'll go with. It is also less than shipping it back to the manufacturer (I've had it too long, and it's been worked on so no warranty). Thanks again for the replies!

Is the core for these soldered or welded? I have access to a metal band saw and a friend who can weld aluminum. I would add that a stop leak for aluminum only worked through the summer. So, is this the way to go? It's cheaper than a new replacement.
I have repaired an aluminum radiator using those "bond a coke can to another coke can" solder-type rods. You know the ones- usually sold at swap meets and flea markets by a hungover-looking dude who looks like he'd rather be anywhere but there? That stuff. Believe it or not, it DOES work. In my case, I dimpled the pinhole down w/a sharpened then blunted wooden dowel (so as to dent the area down, but not open the hole up any more than it was), then built the area back up using the solder stick. Still holding pressure in my P-U, been about 10 years now.

327NUT Have you tried calling them on the phone? I just did and spoke to Shaun, he said he hasn't received any emails lately reg. a leaking rad. but would be glad to hear from you. He also said that they have a full 2 yr. warranty on their units......BUT if the rad. has had an attempted repair by the owner or another shop then that would obviously void the warranty. Since they built it I would definately call them and see what options you have. (812) 897-5805

46highboypu 327,thanks...
I agree, my PRC radiator is pretty but it still leaks. I emailed them about the possibility of them repairing it but no answer. So I'm still looking for a solution other than spending another $400.

327NUT Is the rad. a Griffin? With the prices of alum. rad. coming down I wouldn't bother with a perpetual leaker, no way to know if it will start leaking somewhere else. I paid $400 for my PRC fully tig welded rad. and it is a work of art.
