What It Helps Address

• Coolant leaks at the heater circuit
• Restricted heater flow from a deteriorated hose
• Loss of cabin heat caused by cracked or swollen hose material
• Incorrect hose routing on vehicles with curved or long-hose layouts
• Replacement needs for Dodge Ram 1500, Dodge Ram 2500, and Dodge Ram 3500 heater outlet applications

Installation Notes

Match the hose routing, end locations, and notes in the fitment list before installation. Confirm whether the vehicle uses A.C., auxiliary A.C., or a curved/long-hose configuration, since those details affect application selection. Inspect adjoining heater fittings, clamps, and metal tubes for corrosion or wear before installing the new hose.
