Check out this thread: http://www.thecj2apage.com/forums/im-doing-this-for-science-and-cooling_topic28190_page1.html?KW=radiator

He has the pics on page 2 but it seems to be a good option and besides the color and some angels it looks pretty stock... ish...

I have the early grill and I'd kinda like to keep it that way even though my Jeep is a mutt at this point. I kinda like its muttiness but I'd rather not modify it too much...at least at this point. That being said a 3a radiator probably could be modified to fit easily.

You're correct, 3A (and very late 2A) radiators are side mount rather than bottom mount. If you have a later grille it will work (or it could probably be modified to work)

Damar the offer is intriguing. Two questions...

Doesn't the 3a mount to the grill shell instead of being frame mounted and how much would it cost to ship a radiator from Wisconsin to NY?

Or you can have a nice 3A radiator from me for $50 plus shipping. It has been professionally cleaned, bad areas of soldering replaced and painted.Big smile

This is the radiator I am using on my cj2a with a 225 v6.  http://www.autozone.com/autozone/parts/1966-Ford-Mustang/Radiator/_/N-iyn02Z9pdak

It is cheap, has a lifetime warranty, fits very well, and is not aluminum.  Oh I can also get it locally and trade it in locally if it starts leaking.  For a flat head you will have to have the lower port moved, and most small radiator shops charge about $30 to move one.  Now of course that would void the warranty.  My experience with autozone is that they would never notice that the port was moved, even if you pointed it out to them.

This is also a three core radiator instead of the two core that most of the aluminum racing rads.  Remember they are designed for racing AKA going fast.  I don't think any one with a flat head would describe their vehicle as going fast.  The brass will give you much better heat transfer and more surface area for those slow crawls up the trails.

There was some brief conversation about YJ radiators...

I have a buddy with a great YJ radiator but when we tried it, it was to tall to clear the hood on my 2a. Am I missing something?

For my 43 willys build I bought the smallest summit racing radiator with the chevy outlets because I am running a 4.3, the radiators are made by Nothern in the usa, I have one in my tj and it works great very nice welds and quality. The racing radiators are cross flow two core wich out cool a four core brass. I have not mounted the radiator in the 43's mb grill yet but it should work with a cj2a grill too.

Well I just bit the bullet and bought a replacement from Walck's for $475 and that included shipping.. And came with the shroud.. I had a guy quote me $300 to recore mine but he renigged and now says $430.. So needless to say.. I told him to piss off.. After that bs.. I'd spend twice that to keep from giving him the work!!

Here is the one I am currently considering. Its a little shorter and about an inch wider than a factory radiator. I will take some final measurements to check the fit next time I am with my jeep.

Any comments/concerns/suggestions?

Here is everything Summit lists with both outlets drivers side and similar height

FWIW, the airflow/coolant flows through the rad are much more important than the thermal conductivity of the aluminum versus brass or copper. That said, be sure and run a good quality 50-50 coolant and a good ground to the radiator to minimize the galvanic corrosion between steel/iron in the engine and body and the aluminum.

:shrug: Then why is it a popular mod? If it wasn't a good idea, then nobody would be doing it. One nice thing about aluminum, it doesn't rot out. I haven't heard any complaints about it at the ECJ5 board...
 
saves weight for race cars. The rest is all hipe.  Just MHO.
