Continental 64225 HVAC Heater Hose

Continental Molded HVAC Heater Hose 64225

Continental 64225 is a molded HVAC heater hose built for coolant routing between the throttle body, thermostat, intake manifold, and related engine components. It is formed to match specific vehicle layouts and is made to handle glycol-based coolant flow while meeting SAE 20R3EC Class D1 and D2 requirements.

The Continental Molded line focuses on application-specific hose shapes for direct replacement use. This molded hose helps maintain the correct routing and bend profile needed in tight engine bays, including Subaru Legacy, Subaru Outback, Honda Pilot, and Acura TL applications.

Key Features

• Molded hose profile for application-specific coolant routing
• Designed for glycol-based coolant transfer to and from the heater core, bypass circuits, and related components
• Built to SAE 20R3EC Class D1 and Class D2 specifications
• Resistant to electrochemical degradation (ECR)
• 0.310 in. inside diameter at both ends
• 7.310 in. hose length
• Continental part number 64225

Detailed Description

Continental 64225 is an HVAC heater hose engineered for precise coolant flow in molded routing applications. With a 0.310-inch inside diameter and 7.310-inch length, it is sized for vehicles that require a compact, formed hose between the throttle body, thermostat, pipe, or intake manifold. The hose construction is specified for glycol-base coolant service and includes resistance to electrochemical degradation, which is important in modern cooling systems where hose integrity and coolant compatibility matter.

This part cross-references Gates 19442 for the same application. It is a direct-fit option for many Subaru, Honda, and Acura cooling-system routes, including 2010-2019 Subaru Legacy throttle body outlet, 2010-2019 Subaru Outback throttle body outlet, and 2009-2015 Honda Pilot throttle body to thermostat configurations.

What It Can Help Solve

• Coolant leaks at a cracked or aged molded hose
• Incorrect hose routing after a cooling-system repair
• Restricted coolant flow between the throttle body and thermostat
• Heat-related hose deterioration in ECR-sensitive systems
• Fitment issues when replacing a formed hose on Subaru, Honda, or Acura models

Installation Notes

Verify the hose path, end diameters, and molded shape against the original part before installation. This hose is listed for multiple positions, including throttle body outlet, throttle body inlet, throttle body to thermostat, throttle body to pipe, pipe to throttle body, and pipe-1 to intake manifold applications. Confirm the vehicle-specific routing on Subaru Legacy, Honda Pilot, and Acura TL models to ensure the correct orientation.

Quality Assurance

Continental specifies this hose to SAE 20R3EC Class D1 and D2 standards and notes resistance to electrochemical degradation for added durability in coolant service. Continental 64225 is built as a molded replacement hose for application-specific cooling-system routing.
