Detailed Description

Continental 66307 is a molded radiator coolant hose engineered for upper cooling-system routing on compatible Nissan and INFINITI applications. The hose uses an EPDM tube and cover with synthetic reinforcement to meet or exceed SAE 20R4EC Class D1 requirements, helping it handle the demands of coolant circulation in a factory-style layout. Its molded design and OEM configuration support accurate fitment in vehicles such as the Nissan 370Z, INFINITI QX50, and INFINITI G37. If you are replacing a worn upper radiator coolant hose, 66307 provides a direct-match style solution for the specified applications.

What It Helps Solve

• Coolant leaks from a cracked or deteriorated hose.
• Improper hose routing caused by a misshaped replacement part.
• Cooling-system service needs on upper hose applications.
• Fitment issues when an exact molded configuration is required.

Installation Notes and Tips

Verify hose routing, inside diameter, and molded shape against the removed part before installation. Confirm compatibility by year, make, model, and upper hose position for the specific vehicle application. Part number 66307 should be matched to the original cooling-system layout to ensure correct installation.

Quality Assurance

Continental states that the hose configuration is based on exact OEM specifications for a precise fit. The construction also meets or exceeds SAE 20R4EC Class D1 standards.
