wow thats cool. so if a car radiator looks like it has copper tubes its not copper but brass right? and copper fins? if the fins are copper would it be sheet copper? i saw a ford truck he said it was made in the 80s does that mean its got brass tubes or are they copper? from what i could tell the radiator looked like the ac kind. do they weigh more than the ali ones are they more than 25lbs? also how much will i get for the fans on the radiator on a car there is 2 small fans attached to the radiator can i take those off without draining the radiator? the radiator is staying in the car my grandma is going to just give me 10 dollars for it its a 01 lumina so i think its not copper tubes right? my dad poked a hole in our car radiator he ran into a tree limb in the road dont have to worry about draining that fluid cause its gone=) at least he only damaged the radiator but hey its free for me=)
