Best Answer

In the early days radiators were made of brass and copper due to the superior heat dissipation the metals provide, they were very heavy and were soldered together. Newer cars have radiators made of aluminum with plastic/composite tanks mostly because it's cheaper and easier to manufacture and also because they are lighter, and the lighter the car is the better MPG and tail pipe emissions they will have.
