Continental 64552 HVAC Heater Hose - Heater Control Valve To Heater Inlet

Continental HVAC Heater Hose for Ford Expedition

Continental 64552 is a molded HVAC heater hose for coolant transfer between the heater control valve and heater inlet on 2005-2006 Ford Expedition models. It is built to handle glycol-based coolant flow in heater circuit routing while maintaining the formed shape needed for a direct-fit replacement.

Key Features

• Fits 2005-2006 Ford Expedition, heater control valve to heater inlet
• Molded hose profile for the specified HVAC routing
• 0.690 in. inside diameter at both ends
• 11.000 in. hose length
• Built to SAE 20R3EC Class D1 and Class D2 specifications
• Resists electrochemical degradation in coolant service

Product Details

Continental Molded 64552 is engineered for heater circuit coolant movement, transferring glycol-based coolant to and from the heater core, through bypass routing, and across other vehicle cooling system components. The molded construction helps preserve the original hose path on the Ford Expedition heater control valve to heater inlet connection, supporting a clean replacement for the factory-style layout. This part cross-references Ford OE numbers 5L1Z18471AC and 5L1Z18472BB for the same application.

As part of Continental’s Molded line, this hose is made for formed HVAC and cooling-system routing where a straight hose will not match the vehicle’s path. Continental 64552 is a practical choice when replacing a worn heater hose on a 2005 Ford Expedition or 2006 Ford Expedition with the correct molded configuration.

Common Problems This Hose Can Address

• Coolant seepage at a deteriorated heater hose
• Restricted heater coolant flow from a collapsed or softened hose
• Incorrect routing after a previous repair
• Cracking, swelling, or hardening from heat and coolant exposure
• Loss of heater performance caused by hose leakage or blockage

Installation Notes and Tips

Verify the hose path, end diameters, and molded shape against the original part before installation. Drain coolant as needed, inspect the heater control valve and heater inlet connections for wear, and replace any damaged clamps or sealing surfaces during service. Confirm the hose is routed without twist or tension so the formed shape matches the factory layout on the Ford Expedition.

Quality Assurance

Continental manufactures this heater hose to meet SAE 20R3EC Class D1 and Class D2 requirements and to resist electrochemical degradation in coolant service. Part number 64552 is built for the specified HVAC heater hose application on 2005-2006 Ford Expedition models.
