Product Details

This Continental molded hose is engineered for coolant movement between system components where a formed hose shape is required. The 0.500-inch diameter and molded profile support proper routing in tight engine-bay layouts, while the hose construction is specified to handle glycol-based coolant in radiator and heater circuits. For buyers searching for a Toyota Tundra oil cooler to engine hose or a Honda Accord heater to valve hose, Continental 63530 provides a direct-fit option in the listed applications.

Compatible With 2000-2002 Toyota Tundra, Oil Cooler To Engine; 1985 Honda Accord, Heater To Valve; and 1984-1985 Honda Accord, Heater To Valve-1. The part number 63530 is also useful when comparing replacement options for the same vehicle routing and hose dimensions.

What This Hose Helps Address

• Coolant leaks from a cracked or aged molded hose
• Restricted coolant flow caused by hose collapse or softening
• Improper routing when a straight hose does not match the factory path
• Heater circuit service needs on Honda Accord applications
• Oil cooler to engine coolant line replacement on Toyota Tundra applications

Installation Notes and Tips

Verify hose routing, inside diameter, and molded shape against the removed part before installation. Confirm the connection points are clean and free of debris so the hose seats fully on the fittings. Because this hose is application-specific, use the vehicle position listed in the fitment data for the correct routing on your Toyota Tundra or Honda Accord.

Quality Assurance

Continental manufactures this hose to meet or exceed SAE 20R4EC Class D1 radiator hose specifications, providing a standards-based replacement for listed coolant system applications. Part number 63530 is built for the demands of glycol-based coolant transfer in the vehicle’s HVAC and cooling system.
