Continental 64376 Engine Coolant Bypass Hose

Continental Engine Coolant Bypass Hose for Toyota Land Cruiser

Continental Molded part number 64376 is an engine coolant bypass hose built for glycol-based cooling systems. It routes coolant to and from the heater core, bypass circuits, and related engine components, with molded dimensions that match the specified application.

Key Features

• Hose inside diameter: 0.880 in. at both ends
• Overall hose length: 6.180 in.
• Built for transfer of glycol-base coolant through heater and bypass circuits
• Meets SAE 20R3EC Class D1 and D2 specifications
• Resistant to electrochemical degradation (ECR)
• Continental Molded line construction for application-specific routing

Product Details

This Continental 64376 coolant bypass hose is specified for 1965-1987 Toyota Land Cruiser applications and is shaped for the molded routing used in the cooling system. It is sized with a 0.880-inch inside diameter on both ends and a 6.180-inch length, making it a direct-match service part for coolant transfer between the heater core, bypass passages, radiator bypass routing, and other engine cooling components. The Continental Molded product line focuses on formed hose applications where exact routing and fit are important, and this part number 64376 follows that approach for Toyota Land Cruiser cooling service.

This part cross-references Gates 21222 for the same application.

Common Problems This Hose Can Address

• Cracked or hardened coolant bypass hose material
• Coolant seepage at molded hose connections
• Restricted coolant flow through heater or bypass passages
• Incorrect hose routing from a previous repair
• Replacement needs on 1965-1987 Toyota Land Cruiser cooling systems

Installation Notes and Tips

Verify the hose routing, end diameters, and molded shape against the removed part before installation. Inspect adjoining heater core, bypass, and radiator connection points for corrosion, scale, or damage that could affect sealing. Use clean coolant system surfaces and confirm the cooling system is properly filled and bled after service.

Quality Assurance

Continental specifies this hose to SAE 20R3EC Class D1 and D2 requirements and notes resistance to electrochemical degradation, supporting consistent performance in coolant service. Part number 64376 is built for the listed Toyota Land Cruiser fitment and cooling-system application.
