Description
Premium HVAC Heater Hose Assembly – For Dodge Durango (2001-2003)
Ensure consistent cabin warmth and engine cooling with this Professional-Grade Heater Hose Assembly. Over time, factory rubber hoses become brittle and prone to high-pressure leaks. This dual-hose assembly is engineered to withstand extreme engine bay temperatures and constant coolant vibration, restoring full flow to your heater core and preventing overheating issues.
Optimized for V8 Engine configurations (4.7L and 5.9L).

Key Performance Features
- Direct OE Replacement – Matches original dimensions and routing for a perfect fit. Replaces OEM part 5019795AA and aftermarket 626-647.
- Reinforced EPDM Rubber – Constructed with high-strength synthetic rubber that resists heat degradation, electrochemical cracking, and oil contamination.
- Pre-Shaped Design – Formed to the exact contours of the Durango engine bay to prevent kinking, which can restrict coolant flow and cause heater core failure.

- Corrosion-Resistant Fittings – Includes durable plastic/metal connectors designed to survive years of exposure to hot coolant.

Installation Guide
Follow these steps for a safe and secure installation:
- Safety First: Ensure the engine is completely cold. Coolant systems are under high pressure when hot.
- Drainage: Partially drain the radiator to prevent a mess when disconnecting the heater core lines.
- Removal: Use hose clamp pliers to release the old clamps at the firewall and the engine block. Remove the old assembly.
- Installation: Route the new Heater Hose Assembly exactly like the original. Connect to the heater core first, then the engine.
- Finishing: Secure all clamps, refill with a 50/50 coolant mix, and run the engine with the heater on "High" to bleed out trapped air.
