I have installed a newr aluminum radiator in my bus and never looked  back.

The old radiator was copper and full of crud and deposits. Obviously the  old
radiotr was performing poorly because of its age. And I can't speak to the
different metal qualities.

I can only say I'm real please with the cooling of the new aluminum  radiator
and for a while I lived in the Valley were it's typically 100 for days  on
end in the summer. Never a glimmer of a problem so far--knock wood.

Also the radiators have gotten so cheap from list vendors they could almost
be replaced every time you tune up. That's coming from a guy who paid $450 for
 his several years back.

Best,
