47-55.1 radiator install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, I finally got my new radiator installed today.
I've been running an old stock copper / brass radiator for 30 + years and it finally started to leak. Local rad shop wanted $750. to re core it.
After talking with a lot of local hot rodders, they recommended going with a 4row aluminum radiator. The idea is with the heat here, it was go big or stay home.
Anyway, I got a great deal from Summit racing on a 386037. Cost me $340.00. I did have to make up a 1/4" spacer to go between the core support and the radiator otherwise the radiator would rub on the cross bars in the core support.
So any way, its in and no leaks. Tomorrow I will take it out for a test run.
Wish me luck.

update; Took a quick run from Yakima to Ellensburg & back. About 35 min. each way over a couple of 2500' passes. Got home with no leaks & temp gauge was at 176 deg. Outside temp is 92 deg. Now to find a good overflow bottle. I think this was worth the time and effort.

Life should be good if you did that in 90 something plus today. I have a round polished aluminum one stashed in my stuff for mine that I bought about the same time I bought the radiator.

Amazon shows a bunch of different ones as does Ebay https://www.amazon.com/s?k=radiator+...refreshed_1_13
