The Mishimoto Top Heater Hose Upgrade fits the 2007.5-2009 Dodge Ram 3500 with the 6.7L Cummins and replaces the leak-prone factory quick-disconnect at the engine.

Install Difficulty: DIY Possible
Replaces the factory heater hose quick-disconnect with hand tools; typically installs in 45-60 minutes and requires a partial coolant drain and refill.

Product Overview

This upgrade swaps the OEM plastic heater hose quick-disconnect for a durable O-ring-less -10AN connection, eliminating a common Cummins coolant leak point.

The improved fitting delivers a reliable, seamless coolant flow path to the heater core. Backed by the Mishimoto Lifetime Warranty.
