Is there real improvement with aluminum radiator?

I have a 1980 CJ with 258 and have fought heating problems for a couple of summers here in the hot Arizona desert. I was looking at several aluminum radiators and would like to know if anyone can report on the "advertised" temp drops of 20 degrees? Thanks.

What is causing your cooling problem, the stock radiator should do just fine. I lived in S. AZ for 11 years, never had a problem with my CJ-7 with 258. IMO, don't waste your money on an aluminum one, make sure your radiator is clean and your fan clutch is working properly.

An aluminum 4 core radiator will easily drop your temps 20 degrees. But you arent running anything out of the normal. I would think you could maintane your temps with your set up with a stock radiator in good condition, a good fan clutch, thermostat, at least a 19 lb cap, and a good water pump. Mkae surethe radiator has good air flow and isnt to obstructed by the winch or other objects.
