Has anyone used this radiator? what did you think? Im wondering about the hose outlet sizes? https://www.summitracing.com/parts/rad-gma546ak/year/1972/make/buick/model/gs-455
The inlet/outlet holes seem small. On my stock radiator they were 1-1/2". I got a Dewitts for cheaper than that(with their 15% off sale) but regularly with trans cooler they're $599, made in America, & have a lifetime warranty. Now I just installed it so I can't give you any performance or reliability as of yet. Just my.02 Kyle

The one I bought and installed into my '72 was a perfect fit, others received a different design and had issues.
No. I have a mechanical fan & am not really sold on electrical fans. To each their own though. The inlet/outlet are still the wrong size though. Kyle
Does anyone have the measurements on their original GS radiator. Im at work and dont have access to mine.
I filled out an order sheet with all the correct measurements and mine arrived perfect fit. It was just a bit fatter than the stock so I had to make adjustments to the shroud.
When I got mine(a few weeks ago) Jesse says now they have a part number for the Buick radiators. Mine fit correctly as well I’m just having to adjust the isolating pads. So I didn’t have to fill out a form. Everything measurement wise is the same as a Chevelle except for the inlet/outlet. Ours being 1-1/2”. Kyle
Cold Case is just around the corner from my place. I purchase one and it did not fit either my 71 or 72 GS. I drove over to Cold Case with my original two GS radiators to prove they are not the right dimensions. They noted to me that they were designed for the GTO and assumed they would fit other A-Body cars. I do have to give them credit because they out of there way the pull out other radiators to see if it would work but no match. I did notice a radiator in their showroom and I ask what it was for, they noted it was there prototype radiator before they made change. We measured the prototype and it was a perfect fit and been in my car for a few years. So just measure what you have against Cold Case radiator measurements.
