I have a 1948 3/4 ton chevy truck with a 250 cu inch 6 cylinder, the original harrison radiator 3121499 works well (usual running temp 190 t0 200 ) but has sprung a slow leak out of the back of the core. I think this radiator is a heavy duty radiator used on commercial 3/4 thru 1 1/2 ton trucks, it measures almost 4 inches across the top, my question is it usually cost effective to repair this radiator, it looks pretty good otherwise or would you suggest just getting a new one and if so which would you suggest, I would like to keep this stock radiator if possible with its added cooling capacity since I use it with a trailer in 100 degree heat. also I have found a fan shroud which I plan to install once the leaks taken care of. many thanks
