Mishimoto 2007.5+ Ram 6.7L Cummins Top Heater Hose Upgrade

If you're working on your 2011-2024 Ram 2500 with the 6.7L Cummins engine, you know the factory heater hose connection at the engine can be a weak point. This Mishimoto Top Heater Hose Upgrade directly addresses that by replacing the factory quick-disconnect fitting with a more reliable O-ring-less -10AN connection. This change helps prevent coolant leaks and ensures a more consistent flow of coolant through your heater core.

This upgrade is designed for a straightforward installation, with pre-installed thread sealant on the AN fitting to make sure your connection is leak-free right from the start. By eliminating the potential failure point of the factory quick-disconnect, you're adding a solid layer of durability to your truck's cooling system. It’s a practical change that offers peace of mind, especially if you're pushing your Cummins a bit harder or just want to ensure long-term reliability.
