I have a 57 GM car with factory AC. The original radiator was a 3 row. The size of the tubes were  fairly small. The radiator core  was replaced with a 2 row, but the tube size is larger. How does the cooling capacity compare to the 3 row? Thanks, Bob

Bob:
  The main factor for radiators to radiate heat is how many square inchs of the vertical tubes exposed to air (wind). Large cross section tubes, which run allot of water but not much exposure to air, would not radiate as much as multiple smaller cross section tubes. So, determine the cross section of the tubes on each radiator and you would answer your question. Other factors are thickness of the tubes' metal, shape of the cross section (round, rectanglular ...etc), hight of the tubes, volume of the air, and material to name a few. I hope I didnt complicated things. Happy motoring.
