    The radiator for my v6 has two leaks in the top tank - one is more of a seep that just leaves some mineralization, but the second makes it non-functional. So decision is either to replace it with something like this (which I believe is the only, or one of very few new options):
    1970 JEEP CJ5 - 3.7 liter V6 RADIATOR ALL ALUMINUM 20 INCH CORE, BUICK V6

    Or to try and get it fixed. There seems to be a good repair shop in Grand Junction, which is where it broke it down, and that is the guy that took a quick look at it and found the second seep leak. He also commented on some other low quality solder jobs from previous repair. The core was replaced at some point according to his trained eye, and he said its totally repairable, and would actually be more functional than one of the new all aluminum ones. His estimate would be $200+ but its would be good as new. I would be happy to have him do it but with the weekend, then the holiday and busy workload he couldn't do it for a couple weeks and I don't live near Grand Junction - was just passing through. Probably should have left it with him anyway, but it would be an 8+ hr roundtrip drive to go pick it back up - and they aren't open on weekends.

    Trying to decide what to do - I haven't had much success finding anyone here in the front range that does this kind of radiator work. I took in to the recommended shop a couple years ago to get it tanked, rodded and pressure checked and to repair a leak at the outlet nipple. It immediately didn't work from day 1 (outlet leak was still a problem) - so I took it right back. The did get it fixed after a second try - but I've never been very sure of the quality - and from my untrained eye it didn't look like it was tanked very well. Don't intend to go back to them. That leaves me traveling a hour or two north or south for unknown shops - and that is a big hassle with my work schedule and normal closing time of 5pm.

    For $275 shipped to my door, I would seriously consider the new one. What are the concerns with these all aluminium radiators? Anyone have personal experience? I am on radiator research right now in terms of learning about 2 and 3 row cores and cross-flow etc.

    I know a long time reputable shop in the Springs if you have to do that, but I find it hard to believe that there's not a good shop somewhere in a city the size of the Denver metro area...
    My personal opinion is that I'd rather have a well repaired stock radiator than an aftermarket replacement of unknown quality and dubious fitment.

    Old time radiator shops are hard to find. In another 10 years or so there probably won't be any left.

    Ask the guy in Grand Junction if you ship it to him, and he repairs it, will he ship it back.

    I had the same issue in NW Arkansas, no rad shops anymore. Took it to Houston with me while visiting my father and had Errol at Advance Radiator look at it. Really great guy, dropped what he was doing to pressure and flow test it while I watched. He ended up removing the tank, cleaning the core and re-soldering the whole thing for $120. I think I gave him $150 because his customer service was second to none. He did say my original copper/brass rad was far better than the aluminum ones...he said those can't be repaired or cleaned; basically disposable. If you have to ship it, I would suggest contacting Errol.

    I took my M38A1 gas tank into a local radiator shop several years ago right after buying it. Lots of pinholes on the underside and the A1 tanks are expensive to buy and difficult to source, so repair was the best option. Their fix is still going strong.

    Anyhow, what was most noticeable about the shop was the number of big rig radiators in there being worked on. I commented about it to the owner and he said it was their bread and butter. With the disposable aluminum radiators dominating in the replacement realm for general use, only the radiators used in large trucks or other heavy equipment was routinely being repaired.

    That's a long way of suggesting you look for a shop that does that kind of specialized work. The local shop had no problem with taking care of my A1 radiator when I asked him if he'd work on it should it need repair or re-coring. There must be something like that in the Denver area. You might try asking at the shops that work on OTR trucks and other heavy duty rigs.

    Maybe radiator shops will go the way of the old "speed" shops of the 50s and 60s. As a kid, my first job was as a driver for an old school radiator shop in San Diego (Joe's Radiator Shop! I worked for Bud, Joe's nephew) Hot-rodded all around town in a '65 El Camino with a 283 and powerglide. Fortunately didn't spend much time in the shop as the fumes, acids and heavy metals are hard on the body. The EPA? What's that?

    Sounds like you'd be happier getting the original repaired. A re-core is pricey, but it was pricey back in '73 as well. A rod and repair is very reasonable.

    I agree that it probably should have been left with the gentleman in Grand Junction. He accessed the problem and you were comfortable with him. You didn't say if you were charged for this. If it were me, I would make arrangements to have him fix the radiator. At the very least, call him to discuss your options.

    This is exactly what I noticed at the shop in Grand Junction. There were two long haul OTR trucks trying to get immediate service with leaking radiators and most of the radiators he was working on were for the heavy equipment associated with the oil and gas industry in the area. Some of the radiators in the shop were bigger than my jeep as a whole I think. He wasn't too interested in shipping, and it would have meant a day off work for an 8hr drive to go get it. I asked him about shops in the front range - he had no recommendations but did suggest I contact a friend at the Denver Performance Radiator who used to do all the same kind of work - then they found they could make all their money just selling and distributing new plastic radiators for all the passenger vehicles in the metro area. There ain't a lot of farm equipment around here any more. Its become a replacement type industry and not repair for passenger cars. I did find a shop up in Ft Collins that sounds hopeful - but it ain't close and I don't have a flexible work schedule during the school year to drive up there.

    Gonna go the repair route first if I can find a shop. Here are a couple that I will contact after the holiday weekend and see what they say. Searching with a filter for OTR trucks seems to bring some better options than standard radiator repair. The second one comes with a recommendation from a member of my local 4x4 club.

    Thanks Doug - I'll take the name and contact them. The springs isn't that far I can normally find an excuse to go down there as I lived there for 6 years and still have some good friends.

    Let me know if I can help out in any way.

    Edit: I'm going to ask the guys at our Commerce City store if they have a good Denver area radiator shop they use...

    BTW, a lot of heavy duty truck radiators are going to plastic/aluminum these days too.

    I think the Champion CC7071 3 row rated to 500hp is a direct bolt in.
    Except everyone is out of stock almost all the time.
    I have seen them for about $ 210 from couple different places.

    I'm fortunate to have a shop in town that still does "old school" repair. He soldered my radiator while I waited. Yes, lots of BIG radiators in his shop; heavy equipment and trucks.

    From what I know of the radiator world, this is the reality if you want to stay original- it's expensive. But if it's any consolation, it was like that in the early 70s as well (relatively speaking, probably even more expensive back then). Quality and originality costs $. I think it's worth it.

    I had my 2A radiator records at a local shop and I think it was about $400 but he also relocated the lower hose to the right side for the V6.
