I looked on e-bay and saw a new 3 row aluminum radiator for $199. It looks just like the original, but says the top inlet is 1.5" and the lower outlet is 1.75". My radiator inlet measures 1.25" and the lower is 1.5". I will need to call them to find the differences. Does anyone have any experience with these or other ideas for replacement?

I've had good luck with U S Radiator ...link... ...link.. | | | | | Joined: Sep 2010 Posts: 100 'Bolter | | 'Bolter Joined: Sep 2010 Posts: 100 | I too, recently replaced a 1946 Chevrolet 1/2 ton pickup original radiator with a new one from US Radiator. Great price, quick ship and awesome product. Truck temp runs 170 -180 consistently. | | | | | Joined: Nov 2007 Posts: 25 'Bolter | | 'Bolter Joined: Nov 2007 Posts: 25 | Thanks for your input. I have a new radiator ordered from US Radiator.

But, not perfect. Three complaints that I have are:
1st. The lower tank is not the same shape as the original
tank. If you use the crank to turn your engine during tune-ups
the bottom tanks are straight across and block the path. You
will no longer be able to use a crank.
2nd. The upper tank is not the same shape as the original tank.
Additionally the top of the new radiator will set lower in
the core support than an original tank.
3rd. The support brackets were not a good fit to the original
core support holes and were not soldered on the core straight.
I had to open up a couple of holes to make it fit.
As with the Chinese made items, just a little more effort
with their tooling and assembly fixtures and they would
have a perfect replacement part.

What I didn't like was that the filler neck follows the contour of the top of the radiator as opposed to being flat and straight. But what a wonderful radiator! With the updated core I won't have cooling problems for a very long time! | | |
