What It Helps Address

• Coolant leaks caused by cracked or aged molded hose sections
• Restricted coolant flow from damaged internal hose passages
• Improper routing when the original molded hose no longer holds shape
• Thermal management faults tied to deteriorated hose connections
• Service replacement needs for Tesla Model 3, Model Y, Model S, and Model X coolant circuits

Installation Notes

Verify hose routing, connector style, and end diameters before installation. Confirm the vehicle-specific application by year and system location, since this hose is listed for multiple Tesla thermal management positions including battery return, rear drive unit inverter to oil cooler, and molded thermoplastic coolant hose applications. Inspect mating connectors and sealing surfaces for wear or contamination before assembly.

Quality Assurance

Gates has more than 75 years of experience in automotive hose manufacturing and thermal management solutions. The 65002 is backed by that engineering background and the Gates molded coolant hose product line focus on reliable coolant system performance.
