I had my rad recored entirely with a much more efficient core, but I still only run a 7 lb. cap with an overflow tank.
When I took my old rad in and had it checked it failes so badlt it was beyond hope. The old soldered accordian cores just aren't made to be repaired as easily as the finned tube type in modern rads. The bonus is tha it gets up to the thermostat opening temp and doesn't get much hotter, even under load.
Wasn't a cheap fix, but it looks great and works bettr, just one of the few things I dont have to worry about breaking. y waterpump on the other hand,...

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
