Ram heater core fixed with RMI-25
“I was doubting anything would help but it did! I put in 16oz of RMI-25 and have about 20 hours of driving so far. The heat in my 2018 Ram 2500 went from barely warm, maybe 110F max to it now gets warm enough, at least 140F, to drive comfortably in 20F degree weather. My windshield melts again! Seems to keep getting hotter. The cost is nothing compared to a heater core replacement. I am very happy I tried it and plan on telling anyone I come across with the same issue. Incredibly fast shipping too! Thank you very much!“
