The Mishimoto Top Heater Hose Upgrade fits the 2019-2024 Ram 3500 with the 6.7L Cummins and replaces the leak-prone factory quick-disconnect at the engine with a reliable -10AN connection.
Product Overview
This upgrade eliminates the OEM heater hose quick-disconnect fitting that commonly fails and leaks coolant on 6.7L Cummins trucks. In its place, Mishimoto uses an O-ring-less -10AN connection for a positive, leak-free seal.
The result is dependable coolant flow to the heater core and one less failure point on the Cummins cooling system. Backed by the Mishimoto Lifetime Warranty.
