How many \"cores\" is my radiator?

Crazy question, but how do I tell if I have a 3 core radiator or a 2 core radiator. When I look down the hole in the top of the radiator, I see that it is 2 holes wide. Does that mean it is a 2 core radiator? I have a CJ with an auto and A/C so I assumed it would have a heavy duty radiator, but now I don't know.

There are rows of either aluminum or copper/aluminum tubing. If you look at the side of the radiator, you will see either 2 or 3 rows of this tubing. That's how many cores you have.

[img]/wwwthreads_images/icons/blush.gif[/img] Er.....ah....not to put too fine a point on it,[img]/wwwthreads_images/icons/blush.gif[/img] but the CORE of a radiator is that portion which is between the tanks.......the part that is finned. The TUBES are the water passages that go through the core of the radiator. You can usually count them by peering through the filler neck, or looking closely through the core. Sometimes the rows of tubes are staggered to catch the air better. Many of the older cars had four row radiators because the older engines did not cool well. Nowadays, three rows is considered a heavy cooling option.[img]/wwwthreads_images/icons/crazy.gif[/img]
