Aftermarket Radiator

[lameyer]

I have been looking to replace the radiator in my 47 I came across some that are made of aluminum and the top hose connections are bigger than the bottom. Is there a reason for this?

Sounds like a "blem" radiator or one made for another specific application. When I ordered the Griffin aluminum radiator for my avatar roadster I was able to specify the sizes of all the hose connections.

I've heard of some people having cracking problems with alum radiators, especially ones bought on the cheap. stick with a name brand

I had a Griffin on my roadster and it started leaking like a soaker hose. Had 1600 miles on it but just out of warranty. Called them and they said, send it back at your expense. I did and they could not solve the leak but would give me a deal for $80 more than I paid for it and I had to cover shipping. I got a Brassworks unit and 10k miles later is working great and cooler than the Griffin. Can you guess which one I would buy again?

The only reason OEM uses Aluminum Radiators is for weight savings no cooling advanage. Copper/Brass radiators cool as well and are easier to repair if ever necessary.

Cost and weigh savings. Copper is about $3 pound and aluminum is about a dollar.

Walker is top quality! Well worth it.

U.S. Radiator, made in Vernon (Los Angeles) Ca. Either brass or aluminum, excellent quality, fit, etc. If you go aluminum, ,word, is do not paint the fins, just the tanks and mounting frame. I've been to their factory and their equipment is in good condition, cleaworking areas, etc. No need to go with a high efficiency core.

By all means go with Walker there the best people to work with and their products are superior to all others. I have been using them for years. I ordered a radiator for my 39 PU and forgot to tell them that I had a 59A engine in it. The 59a uses a slightly different position on the outlets . When I went to install it I realized that. After talking to them they said return it and they would replace it with the correct one. They did so promptly and did not even charge me for the shipping back to me. Can't beat that kind of professional service. Frank

Is there any particular reason why you don't have the OEM radiator repaired?

[JSeery]

If you need a new one I like Brass Works.

Guess I got lucky. My Griffin is 15 years old and has many thousands of miles on it with no problems.

As already mentioned by several contributors, the Walker is probably the best "bang-for-the-buck radiator choice. However, they are not EXACTLY stock appearing.
