The Stovebolt Site Forums The Shop Area Engine Shop 3/4 ton harrison radiator leak

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

If you can find an honest old time Radiator Shop who knows what to do and how to do it, it would be much better just to have this Radiator repaired than to buy a new one.

When I got my 1946 one ton pick up, it had a couple small Radiator Leaks, and I ran a few rounds of radiator Cleaner through it, then i just poured in a few Tablespoons or so of finely ground Black Pepper.

Far as recall, that took care of it, and it stayed fine for the next 25 years of daily use. I do not believe I ever had those leaks 'soldered', the Pepper plugged them up and I think one of them minutely seeped a little sometimes, and that was all.

If you gave us an idea of were in TX you are perhaps some bolters from that area can advise on a good radiator shop.

you can have it repaired or have it recored.

Thanks,i am in the central texas austin and kings land area if anyone knows a good radiator shop in that area

I had my '55 Harrison flushed,boiled,soldered and painted for $35.00,by a local shop. much cheaper than a new radiator!
