The performance of a new aluminum vs an old sludged and stopz leakz coated copper radiator is not going to be an issue. Now at idle or slow and go speed, if some dfference is noticed, it can be addressed by different water pump and/or main fan (bigger moves mo air at idle). The newly "discovered" aluminum radiator may get guys to fix one of their big problems rather than nursing the truck along with lots of cheap fixes. So while new copper is best, new aluminum beats what is in half the trucks, if not more, that are still on the road. And since the D1 rad also fits things like Rovers and Defenders, there must be a market.

Its been 100+ here in Dallas and Ruby cools off great. stuck in traffic on the hwy, i mean stand still at 106 degrees, A/C on, I only saw 215 on the UG. it instantly cools off with a little movement. at 70mph 185-192, my old rad (copper factory) recently rodded (2 years ago) would peak at 219-220. I think what kept the old rad from ccol as well would be the fins. When I installed the new radiator I was very careful so I would not bend the fins etc. I personally think that is very important. rod as much as you like, if the fins are bent I think you are toast.

This is all very informative. My '96 overheats on many of these California hills even after replacing all my fans. My next step is to flush my radiator. If that doesn't help or does little to stop the overheating, it's good to know that I have several options over the a new factory radiator.
