Continental 64347 HVAC Heater Hose - Heater To Pipe-1

Product Overview

Continental Molded HVAC heater hose 64347 is built to transfer glycol-based coolant through the heater circuit and related bypass paths. It is a molded hose with 0.750-inch inside diameter ends and a 14.880-inch length, made to match the routing used in the listed applications.

This hose fits 2001-2002 Ford Ranger, Heater To Pipe-1, Molded and 2001-2002 Mazda B4000, Heater To Pipe-1, Molded. Part number 64347 is also referenced by Continental 22624 and Febi-Bilstein 22736 for the same application.

Key Features

• Molded HVAC heater hose for coolant transfer in the heater circuit.
• 0.750-inch inside diameter at both ends for matched hose connections.
• 14.880-inch overall length for application-specific routing.
• Built to SAE 20R3EC Class D1 and Class D2 specifications.
• Resistant to electrochemical degradation for added hose durability.

Detailed Description

Continental 64347 is a molded heater hose engineered for coolant movement between the engine cooling system and heater core, including bypass flow where required. The molded shape helps follow the original hose path, while the SAE 20R3EC Class D1 and D2 construction supports consistent performance in coolant service. If you are replacing a worn heater hose on a Ford Ranger or Mazda B4000, this part number provides a direct application-specific solution.

Common Issues This Part Can Address

• Coolant seepage from a cracked or aged heater hose.
• Restricted heater flow caused by hose collapse or internal deterioration.
• Improper routing after a previous hose replacement.
• Loss of heater performance related to coolant transfer issues.
• Degradation from electrochemical exposure in the cooling system.

Installation Notes and Tips

Verify hose routing, connection diameter, and molded shape against the removed part before installation. Confirm the heater-to-pipe routing used on your Ford Ranger or Mazda B4000 application, and inspect adjoining pipes and clamps for wear or corrosion. Part number 64347 should be matched to the vehicle’s coolant hose path and connection points before service.

Quality Assurance

Continental designs this Molded hose to meet SAE 20R3EC Class D1 and D2 requirements and to resist electrochemical degradation in coolant service. Part number 64347 is built for the specified heater hose application and cross-references Continental 22624 and Febi-Bilstein 22736.
