Detailed Description

Continental 63329 is a molded HVAC heater hose for coolant transfer in the heater circuit. The hose is shaped for the listed routing and uses a 0.620-inch inside diameter at both ends, with a 10.200-inch length. Its SAE 20R3EC Class D1 and D2 construction and ECR resistance support use in systems where coolant exposure and electrical degradation are concerns. This part cross-references BBB Industries 19008 for the same application.

For Jeep Liberty and Mazda Miata applications, Continental 63329 provides the correct molded hose profile for the heater-to-pipe connection. Use the part number 63329 to verify the exact routing and dimensions before installation.

What It Is Used For

• Replacing a cracked or softened heater hose.
• Restoring coolant flow through the heater circuit.
• Addressing leaks at the heater-to-pipe connection.
• Correcting hose routing issues caused by an incorrect shape or length.

Installation Notes

Confirm the molded shape, 0.620-inch end diameters, and 10.200-inch length against the removed hose before installation. Match the routing to the heater-to-pipe application listed for your vehicle. Verify coolant condition and inspect adjoining pipes and clamps for wear before reassembly.

Quality Assurance

Continental Molded heater hoses are built to meet SAE 20R3EC Class D1 and D2 specifications and are resistant to electrochemical degradation.
