Product Details

Continental 63526 is a molded heater hose engineered for coolant movement through the HVAC and engine cooling system. Its molded shape helps match factory routing, while the 0.620-inch diameter and 22.010-inch length support the specified Toyota heater hose applications. The hose is designed for glycol-base coolants and meets SAE 20R3EC Class D1 and Class D2 requirements, with resistance to electrochemical degradation for added durability in cooling-system service.

This part cross-references Davico Mfg 19292 for the same application. Search terms such as Toyota Camry heater inlet hose, Toyota Highlander heater to pipe hose, and Continental 63526 molded heater hose align with the confirmed fitment data.

Common Problems This Hose Can Address

• Coolant leakage at a worn heater hose connection
• Cracked or hardened hose material from heat cycling
• Restricted coolant flow to the heater core
• Improper hose routing after a failed molded hose replacement
• Cooling-system service needs on heater inlet or heater-to-pipe locations

Installation Notes and Tips

Verify hose routing, end diameters, and molded shape against the original part before installation. Drain coolant as needed, inspect adjoining pipes and clamps for wear, and confirm the hose seats fully at the heater inlet or heater-to-pipe connection. After installation, refill and bleed the cooling system according to the vehicle service procedure to help prevent air pockets.

Quality Assurance

Continental manufactures this hose to SAE 20R3EC Class D1 and Class D2 specifications and includes resistance to electrochemical degradation, which supports long-term cooling-system performance in the listed Toyota Camry and Toyota Highlander applications.
