The radiator on my '54 235 c.i. has a leaking four row radiator.
It has been moved forward a couple of inches, I assume to allow for
the thicker 4 row unit.
Local guy wants $500.00 to replace the 4 row copper core. (Gulp!)

I see new radiators in the catalogs for $325.00... I assume they're 3 row.
The "desert cooler" radiators are $350.00.... I assume they're 4 row.

Considering the extreme summer temperatures here in Phoenix of daily
110 to 120 degrees.... what's your advice?

BTW.. the engine has a four blade 15 3/4 inch fan.

I apologize in advance for asking all silly/dumb questions. I have 45 years of restoring old cars and trucks but am only now learning about Stovebolts.

I replaced the core in my 53 COE with a 4 row and am happy with it, but then again, I also live in Phoenix, so I should probably let others comment.

My advice would be to stay inside an air conditioned
building when it's 120° outside. But....if you must
venture out......
US Radiator offers several replacement radiators for your
vehicle, ranging from a stock three or four row replacement
to hi-performance. All made right here in the US of A. Take
a look at their site.

As of a few years ago, Desert Cooler was still US Radiator,
that is sold by the original owners daughter. They were just
marketed under the Desert Cooler name. It's been several years
but if I recall correctly from a communication I had with
her, both were the same radiator.

Evil Bay can be your friend when purchasing a radiator. Fair prices and good quality along with fast shipping was my experience. I went with the larger capacity aluminum Radiator. Pleased with the results.

Read and decide

You may have to add a fan shroud to help out.

Not sure how its going to work out but I had my friend pick me up an aluminum radiator at the Charlotte Auto Fair a couple weeks ago for $200. It uses the bigger 1" tubes. I'll be using it for a 261 engine. It came from Dillon Radiator but I think Champion Cooling actually makes them. You can order direct from Dillon and they advertise free shipping..... and have other radiators that "bolt right in". May want to check them out????

Don't know what you've been linking to Gus, my lousy internet
provider is down about 80% of the time and today is one of
those days, in fact it's been that way all week. Doesn't do
any good to complain, they're the only one that can provide
us with service out where we're at and believe me, they know it.
But....it's been a couple of years and my experience with US
Radiator was top notch. Dealt with them direct, not thru one
of the vendors.
Most average car guys wouldn't notice the difference unless
the two radiators were standing next to each other or they
knew enough to look for the text that Harrison embossed into
their upper tanks. The radiator is close but the tank is a
little off, not quite the same shape, as in this picture:
http://www.pbase.com/dennygraham/image/159878909/large
These are both 3 row radiators and I've not had any cooling
issues here in the mid-west even on the hottest days of
Summer. Of course you can't fry stakes on the sidewalk
here in Illinois come July like you can in Phoenix, AZ.

Internet is back up, for a little while. Yes, Alex was the guy
that I spoke with when I ordered mine also.
I lost all my reference material when I made the BIG move out
to the new place, so I can't be sure about anything anymore,
can't trust my memory now a days. But...I think Shawn was the
daughter that I talked with. I had several private messages
with her about the inner workings of US Radiator and they got
their, I'll just say, stuff together out there.
This video is really informative:




Think part of that link is worth re-posting here Gus, since a
lot of the replies back in 2010 were blanked out by the sites
software conflicts with IE.

Hi Guys,
"First time poster. My name is Shawn and I work at U.S.
Radiator. I received a Google alert about this thread, so I
thought I'd jump in and answer some of the questions here.
Hope you don’t mind.

U.S. Radiator is a manufacturer that’s been around for about
40 years. We do make the "Desert Cooler" brand, though others
use the name for offshore rads (more on that later). We are
based in Los Angeles. Cool Craft is a distributor of U.S.
Radiator just like Cap A Radiator, Chev's of the 40s and Jim
Carters.

After reading this yesterday morning, I decided to head into
the shop and do some comparisons and take some pictures for
you. The original radiators used a honey-comb (hexagon)
style core. The "tubes", which aren't really tubes; they are
water passages, are formed by stacked pieces of copper that
have been bunched up then coated with solder. These passages
were on 9/16" centers. In the 50s Harrison developed the
tube and fin style core out of the necessity to cool higher
horsepower engines in a smaller space. They were 40% more
efficient at transferring heat and the bonus to them was that
they are considerably lighter; which means they were cheaper
to manufacture.
This is a picture of the honeycomb style core. You cannot see
the water passages since they are surrounded by all of the
bunched up copper; which we call “fins” now:
http://www.usradiator.com/media/honeycomb.jpg

This is a picture of the tube and fin style core. You can see
that the fin sits between the tubes and doesn't completely
surround them. Also, they are soldered to the tube instead of
to each other. These would account for the lighter weight.
The fins are louvered unlike the honeycomb core. Air is
allowed to flow through the fins, which makes is a more
efficient core:
http://www.usradiator.com/media/tubefin.jpg

I found two ’38 chevy truck radiators; one with an original
core and one that we had re-cored using our “Standard
Automotive” style core. The weight difference was around
9lbs.
In the 10 years I’ve been working for U.S. Radiator, I’ve
never seen one of our tanks split. This last year we
received a complaint about one of our 55-57 Bel Air “Desert
Cooler” radiators cracking near the ribs on the top tank. The
guy took it to a radiator shop to have it silver soldered,
but it would continue to crack. I couldn't understand why
this was happening, but once I received the radiator, I
quickly figured out why. The radiator was an off shore
radiator sold by a company claiming to carry “Desert Cooler”
radiators. Here is a picture of the radiator:
http://www.usradiator.com/media/offshore.jpg

I constantly have to contact companies that are using the
“desert cooler” name on these types of radiators. Heck, I
even caught some of our distributors doing it, though I think
it had more to do with them not updating the radiator
descriptions on their web pages for the more popular
radiators they can buy oversees now.

In the 60s, GM started using aluminum radiators on Corvettes
that came with small block engines. Since aluminum does not
transfer heat as well as copper, they continued to use
copper/brass radiators with big block engines. It wasn’t
until the Japanese developed what is referred to as a High
Efficiency core design (tubes on 3/8” centers), that auto
manufactures moved to aluminum radiators in all of their
vehicles. The move was driven by the lower cost of
manufacturing, not because aluminum is better than copper.
We make a copper core with the same High Efficiency core
design, which allows guys to swap in higher horsepower engines
and keep the durability of a copper/brass radiator as well as
original appearance. Walker Radiator has something similar
as well. I recently posted a page that describes all the core
styles we make:
http://www.usradiator.com/cores

I hope that clears up some of the questions that were raised
here about U.S. Radiator. I don’t have the time to check
back here often enough, so if you need me, PM me.
