Radiator Suggestions
With this 100 Deg heat, my 90 vert with the 360 magnum isn't staying cool. It will slowly climb over time. I have a 3000 cfm pusher fan and a standard 5.2L aluminum/plastic radiator I pulled from a 94 Dakota at the J/Y. The radiator looked like it was a recent aftermarket replacement so who knows the spec's. Any suggestions for a higher capacity radiator that won't break the bank? A 4 core perhaps?

The fan I'm running doesn't have a lot of interference like some grilled fans. It's a perma-cool: http://www.code510.com/high-performa...iABEgJXLfD_BwE

Both at Idle and going down the road. Idle a little worse as the fan obviously doesn't cover the entire radiator and I've read that you really shouldn't run a shroud on a pusher.

Well these are just a few of my thoughts.
1. The higher stall converter will build heat, and IMO you should use an aux. cooler for that. But I dont believe that would be a problem when setting still.....
2. By chance, are you using any kind of underdrive pulleys? If so, the pump may be spinning too slow.
3. If you have a point and shoot thermometer, try reading up and down the radiator to see if its got hot spots.
4. Assuming the radiator is fairly even, I would measure the temp. of the upper and lower hose. Compare the difference in these too measurements, ie 195 and 175 would be a 20 degree split. Then measure one of your other vehicles and see what that difference is. That may give you an idea, if its the radiator and or fan not removing the heat or a flow problem with the pump.
5. Other then the optional 26in width radiator, (and I believe they are single core) I cant find any aftermarket radiator listed as a direct fit in a 92-96 dakota.
6. May take measurements of what you have and see if you could make a universal style work. Again, FWIW I have read that going much past a 2 core does not make much difference.
7. Last thought, I would never buy a used radiator. The new ones are cheap enough, and from what I understand, the corrosion rate, inside the radiator greatly accelerates when they have been drained, ie setting in a junkyard. Something about air along with the antifreeze corrodes quickly.
8. Rock auto has a spectra cu1709 listed for $107.79. Also, here is a link to one from pepboys. http://www.ebay.com/itm/Spectra-Prem...tZFfZd&vxp=mtr
Hope you get this figured out soon.

This is a factory fan on a shelby. My understanding is they were I think 11in and moved about 1200 cfm each. They dont cover the entire radiator, and they pulled through a condenser as well. In short, I dont believe its your fan not covering the entire radiator causing your problem.

1. 2600 stall so something to consider.
2. No underdrive pulley...only 4 pulleys total....alt, ps, crank and wp....all stock for a 360.
3. No point and shoot but I do have a probe...good suggestion.
4. Difficult without point and shoot
5. Dame here.
6. I have a shop that can build one but it's $$$
7. I agree....however this radiator looked like it had just been put on the truck and it still had residual bright green antifreeze in it...so I took a chance.
8. Yeah in my Google searches spectra keeps coming up. Wasn't sure if that was a good brand.

That is good deduction 93 ragtop.
I got a point/shoot thermometer at home despot for less than $20. The Rock Auto radiator for the 92 5.2 and the 94 3.9 are the same. I'm not sure what that means. http://www.rockauto.com/en/catalog/d...,radiator,2172

I have no idea how good these are. but they are cheap enough https://www.harborfreight.com/non-co...ing-61894.html For work, I have a fluke that looks like this one, but I think it was over $100.00.
