Continental 63005 Engine Coolant Bypass Hose

Continental 63005 Engine Coolant Bypass Hose

Continental 63005 is a molded engine coolant bypass hose built for glycol-based cooling systems. It routes coolant between the heater core, radiator bypass circuit, and related engine components, with a 0.750-inch inside diameter and a 5.750-inch molded length for the specified applications.

Key Features

• Molded coolant bypass hose for engine cooling and heater circuit routing
• 0.750 in. inside diameter at both ends
• 5.750 in. molded hose length
• Built to SAE 20R3EC Class D1 and D2 specifications
• Resistant to electrochemical degradation (ECR)
• Continental Molded product line for formed hose applications

Product Details

This Continental molded hose is engineered for direct coolant transfer in bypass and heater-related circuits. It is used in applications that require a formed hose shape rather than a straight universal hose, helping maintain the correct routing in tight engine compartments. Continental 63005 is listed for a wide range of Ford truck, van, and Bronco applications, along with select Hyundai and Chevrolet models, including Ford Ranger, Ford Bronco II, and Ford E-150 Econoline configurations.

This part cross-references Dayco 70799 and Dorman - HELP 80845 for the same application.

Common Uses

• Replacing a cracked or leaking engine coolant bypass hose
• Restoring coolant flow between the heater core and bypass circuit
• Addressing coolant seepage at molded hose connections
• Correcting hose collapse, hardening, or heat-related deterioration
• Maintaining proper routing in molded Ford Ranger, Ford Bronco II, and Ford Econoline applications

Installation Notes and Tips

Verify hose routing, end diameters, and molded shape before installation. This hose is listed for multiple positions, including engine-to-pipe, heater-to-valve, heater inlet, and heater outlet applications, so match the vehicle-specific routing exactly. Inspect adjoining pipes, clamps, and fittings for wear or corrosion before installing the new hose.

Quality Assurance

Continental designs this molded coolant hose to meet SAE 20R3EC Class D1 and D2 requirements and to resist electrochemical degradation, a common cause of premature coolant hose failure in modern cooling systems.
