Continental 63642 Engine Coolant Bypass Hose

Continental 63642 Engine Coolant Bypass Hose

Continental Molded 63642 is an engine coolant bypass hose built for glycol-based cooling systems. It routes coolant to and from the heater core, bypasses the radiator, and carries coolant through other engine components in a molded fitment profile.

Compatible With 1964-1969 Dodge Dart, 1967-1969 Dodge Charger, and 1968-1969 Dodge Monaco applications, this hose is sized with a 0.813-inch inside diameter at both ends and a 6.500-inch length. The molded construction supports direct routing in the engine bay, while the ECR-resistant design addresses electrochemical degradation in the cooling system.

Product Details

Continental 63642 is a molded coolant bypass hose for classic Dodge cooling-system service. It is used in applications where coolant must move between the heater core, bypass passages, radiator bypass routing, and related engine components. The molded shape helps match the original hose path in 1964-1969 Dodge Dart, 1967-1969 Dodge Charger, and 1968-1969 Dodge Monaco models. This part cross-references Dayco 70468 and Gates 7334 for the same application.

Common Issues This Hose Can Address

• Cracked or hardened coolant bypass hose material
• Coolant seepage at the hose body or connection points
• Restricted coolant flow through bypass routing
• Heat-related hose collapse or deformation
• Cooling-system service on original molded hose routing

Installation Notes and Tips

Verify hose diameter, length, and molded routing against the removed part before installation. Inspect adjoining heater core, bypass, and radiator connections for corrosion, scale, or damage that could affect sealing. Use clean coolant-system practices during replacement and confirm proper hose seating after the system is refilled and bled.

Quality Assurance

Continental manufactures this hose to SAE 20R3EC Class D1 and D2 requirements and includes resistance to electrochemical degradation for cooling-system durability. Part number 63642 is built for direct-fit service in the listed Dodge applications.
