What This Hose Helps Address

• Coolant leaks at a cracked or aged molded heater hose
• Restricted coolant flow through a deteriorated bypass or heater circuit hose
• Improper routing caused by a hose that no longer holds its formed shape
• Heat-related hose softening, swelling, or surface degradation
• Service replacement for select throttle body to intake manifold and thermostat to pipe locations

Installation Notes and Tips

• Verify the vehicle year, make, model, and hose routing position before installation.
• Match the 0.500-inch inside diameter and molded shape to the original hose path.
• Inspect adjoining pipes, clamps, and coolant passages for wear before reassembly.
• Confirm the hose is seated fully and routed without kinks or twist.
• Refill and bleed the cooling system according to the vehicle service procedure after installation.

Quality Assurance

Continental 64333 is manufactured to SAE 20R3EC Class D1 and Class D2 requirements and is formulated to resist electrochemical degradation, supporting dependable service in coolant-transfer applications.
