The problem with my recored original was the old top and bottom tanks. The core cooled good enough, but the top tank was worn out. The seam would not hold due to thin brass always flexing during heat and cool cycles. No amount of solder was going to keep it from flexing at the seam, it was repaired four or five times for the same problem. I had enough money in it I could have bought two new replacements!

My aluminum replacement has a thicker core, way better air flow, hold more coolant, cost less then the recored old unit, holds way more pressure, weighs less, and cools better. Thats good enough for me!
