I don't understand that because copper is one of the most thermally efficient metals. I understand aluminum is cheaper and lighter, but it is not more efficient

I disagree with total aluminum radiator, I replaced that exact all aluminum radiator that only went two years. I began to smell coolant while pre-Trip and walking around truck,fueling and Yes aluminum radiator is lighter than copper and cheaper. Like CAC they leak slowly!
