Is there some particular reason you want an aluminum one? A short story. Our coach is an '04 Itasca Horizon, 36GD with the C-7 330HP CAT. It's on a Freightliner chassis. Approximately 4 years ago, I developed a leak in the cooling system. It was very difficult to locate the leak. A rear radiator diesel coach has its limits on visual abilities. Well, based on other issues I was having i.e. clogged radiator fins and charge-air-controller fins, and the fact that I was having a leak, it was time to pull that radiator.
Well, it turned out that the radiator was aluminum and basically corroded in the lower left corner. Well, out came all of it. I took it to a radiator repair shop and, they laughed. I said, isn't it repairable"? The shop manager pointed to a shelf that had well over 30-40 aluminum radiators that could not be repaired. He stated that it was quite normal in my kind of situation.
So, a new one, from Freightliner was/is $1,750.00 and takes approximately three weeks to get. He looked at his computer and, within 1-2 minutes, he found an exact replacement in COPPER/BRASS that would fit my frame. I asked about the cooling efficiency vs Aluminum ones. He stated THERE IS NO DIFFERENCE. But, he also stated that at least the Copper/brass ones are much more easily repairable.
And, the really good part(s), it was only $1,200.00 and, what was really, really good, he could have it for me, THE NEXT DAY!
That radiator has been in our coach now for 4 years now and is and has been, working flawlessly ever since. The temps displayed on multiple displays I have, all jive together and it's been consistent.
So, moral of the story, again, I'm not sure why you'd like an aluminum one when a copper/brass one will do just fine and, as you already know, are much cheaper and way more available. Good luck.
