Customers highly praise this radiator's exceptional quality and practicality. The product is made with copper and brass, which ensures consistent cooling in any element, and has an adaptable design, allowing it to fit different hose sizes. Many reviewers regard it as a perfect and affordable replacement, even commenting it's the best radiator they've come across. The bonus feature of an optional brass petcock enhances its usability and quality. Ultimately, they recommended it over other options and believe it holds true to its 1970's-style durability and efficiency.

We bought this radiator for a 1974 Chevy p20 shorty ice cream truck. It was overheating so bad in the California sun! This has totally cooled it down!

Exact fit four row. I discarded the supplied plastic pet c**k and transferred the brass one from the old radiator. The upper radiator inlet is stepped into two sizes. I had to use a hose adapter on my old radiator. This radiator will accommodate both hose sizes depending on year of vehicle.
Would Recommend
I would order from your company again.

I was wondering if the transmission cooling lines were on the driver side. My 82 gmc had the diesel in it and the tranny lines are opposite the gas models. Thank you!
