Blaine.D Posted February 1 Share Posted February 1 Hello y'all, Unfortunately, recently I went to clean my truck interior and was greeted by the terrific pond of coolant in my passenger foot well. I trace the leak to my heater box and most likely my heater core has gave up the ghost. I wanted to see what's the best replacement heater core and has anyone used this one that I found on summit racing. https://www.summitracing.com/parts/rcg-18-11786 Another one I'm considering is just getting one from Advance auto parts. Surprisedly my local store has one in stock. In addition, any tips or tricks to doing this repair would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
