Cooling in Extremes.

Oh I know all that I'm saying an all aluminum (aluminum tanks too) would be cheaper than buying a replacement brass one and probably better at cooling. I read about the DII radiator being used.
I'm not sure I like the idea of plastic tanks. They cant handle the heat cycle. I know all OEM are now plastic but still rather have all metal. Almost every single radiator I've ever replaced in a newer car was due to plastic tank cracks. I think of stuff like plastic intake manifolds that are famous for cracking. Even the replacement intakes for the ford 4.6 have a metal runner to replace the plastic one that always cracks. That tells me that they KNOW metal is better plastic is just cheaper.
So why not go online to a custom radiator place and build an aluminum one? I don't even need one as my brass one is new from PO but if I ever run into this problem I'm going to seriously look into going custom. Even if its the same money. At least the product would be an upgrade.

Plastic intakes save weight, plastic radiators save weight, smaller radiators weigh less and hold less coolant which weighs less...it all adds up.
Once the car is sold CAFE standards do not matter to Ford/Chevy/whoever because when they sold it it meet those standards.
Thats all they car about, avoiding the CAFE fines.

when I went to GM school years ago ( used to be a mechanic) cafe was made simple, we can't sell the corvette and suburban or big block cars that get 5 mpg unless we also sell the chevette, s10 and similar cars, it is another reason why you see 4 cyl and 6 cyl in cars that traditionaly come with v8 it is so they can get an average mpg across their carline to meet CAFE
