Bulletproof cooling system

If you are designing/redesigning a cooling system for your car, the utilization of the aluminum radiator is the best overall product on the market for the dollar. This is not to say that the radiators made from copper and brass are not good, and if you have one that works, don't go out and change for the sake of change. But, the choice of aluminum media will outperform their copper counterparts quite easily even though copper is a better conductor of heat. What is a lesser conductor of heat (aluminum) makes up with more surface area available for heat exchange. A 1.25" two-row aluminum radiator will cool just about anything up to 450hp. If designed correctly, will outperform most 4 or 5 row copper brethren. Not only does aluminum offer a great deal more surface area for cooling, but also has a more rigid structures making for a less likely leaky situation. Also to the credit of this technology and the fact that more modern cars are implementing aluminum, more and more vendors are competing in this product line making for very attractive pricing.
