IN ACTION South Texas Radiator recently had a customer bring his 1919 Chevy model 490 radiator in for repair. Leroy Carranza says this was the oldest model radiator he has physically seen in his 34+ year career. The team pressure washed, internal flushed, soldered around the leaking bottom neck and leaking top tank seam. It also had a small pin hole leaking tube that they back filled with epoxy to stop the leak. The gentleman who owns the car only runs it an average of 25 miles per year and didn't want to invest too much in a core replacement, so they just patched it up. 22 | THE COOLING JOURNAL | March/April 2024
