About Report

Sims Radiator is a part of Metro Atlanta's history! In early spring of 1922, Clay Sims was born into a hard working family on a small tenant farm in Winder, GA. Before serving a tour of Europe in the Army during WWII, he worked as a welder in the shipyards of Mobile, Alabama. He later settled in Atlanta and in 1949 put his trade to use and rented a shop from Hoolie Wilburn across the street from Decatur High School to open a radiator repair shop named aptly - Sims Radiator Service.His brother, Lamar Sims, also a welder, soon joined him and the two worked side by side for the next 35 years, along the way employing and training more repairmen, mechanics, drivers, and their own sons to join them in the business.

They did an amazing job on an original 1967 Cadillac gas tank that was full of sediment and rust. They did it on time, and for the original estimated amount. My new go to shop for radiators and old gas tanks.

I will be going to Sims for all of my restoration projects in the future. I was called and informed of the work being performed at every step. "Would you like us to proceed at this point in the project?" "Yes I would, thank you." Really though, thank you for the great service!

Had gas tank cleaned in a Porsche that had sat in a garage for over 9 years. Excellent and quick service. Will also be taking my radiator, evaporator, condenser, and heater core in for inspection and cleaning. Reasonable prices and superb work.

My radiator was busted. They do a free check and estimate. The price was right and fixed it in 15 minutes. The next week I had a crack in my top tank. It's hard to tell who or what's exactly at fault because I had taken it out and installed it myself; they offered to sell me a new radiator for $135 less the $65 I paid before. Overall I would recommend these folks.
