24hrsparky, my shop manual says the two bigger engines, like the 10 valve, came with copper radiators while all the others including my 5.9 Cummins came aluminum. Doesn’t mention number of tubes. I don’t know if mine is original Dodge but it’s 2 1/4” thick and that’s what the one I just ordered was, it was 185 including shipping and 2 hoses, I’ll let you know in a couple of weeks if it’s working good. Thanks everybody for all the great thoughtsOem was a real 3 row copper n brass 45lb unit .
I just pulled one out , very heavy .
If you tow , get the three row .
I just put in a 185$ China cheapie don't know the rows ,,, this 94 is around 450 hp and just a bomber truck . Never the less with the ac on and full throttle runs , temp never goes up .
Hope this helps , choice is yours .
Uh.......no. When my original 3 row started leaking I bought an OEM replacement. Dodge had changed to a 2 row radiator, which was also a different metal composite. It did not cool even as close to well that the 3 row did. I tried an internet aluminum 2 row. It wasn't any better. I bought an Ice box 4 row. I don't have any issues now with cooling with the heaviest of trailers, in any environment or in the mountains. I put it to the test yesterday on Hwy 97C between Kelowna and Merritt, B.C pulling an 8000 pound TT. That highway is 20+ miles of 7 to 8% climb. With the AC on, 80f outside temp I never exceeded 190 at 50 mph. Your theory doesn't hold water.A 2 row will out cool a 3 row. The more rows, the less efficient the last row(s) are.

I read the link and it makes sense to a point. What it doesn't take into consideration is total coolant volume. If the 3 row has more coolant than the 2 row it will flow slower and have more time to cool. Fin count also plays a part. The more fin contact per row the better, up to a point. You don't want them so thick air flow starts to suffer.What’s more frustrating than sitting on the side of the road with an overheated vehicle? Whether it’s the sight of the steam coming from the hood or the smell of …www.onallcylinders.com
I just copied the one above to show how/why 2 rows (hence larger tubes) cool better, there’s plenty more.
I assume you have a 12 valve? If so, you have the 180* stat and fan clutch. I think the 190* system started in 2000.Where did you order your early fan clutch from? That sounds like a winner. I didn’t know about the bumper either. The fin count being not too high makes sense too.
I’ve read a few opinions here about increasing or decreasing flow rate being good but it seems to me that the flow rate should be whatever the thermostat puts it at, and no farther restriction by the radiator is desirable. A radiator with more flow can’t increase the flow rate that the thermostat restriction gives. So therefore it can’t hurt to have high flow in the rad., just done want it any less than what’s at the thermostst
