Product Details

Gates 18375 is a molded heater hose from the Gates Molded Heater Hose line, built to match the routing needs of modern compact engine layouts. Its EPDM construction supports heater and coolant service, while the molded profile helps it follow the original path at the pipe to throttle body connection.

What This Hose Helps Address

• Coolant hose leakage at the pipe to throttle body connection
• Cracked or hardened heater hose material from age and heat cycling
• Poor hose routing caused by a straight hose in a molded application
• Restricted coolant flow from a deteriorated hose interior
• Service replacement needs on Toyota Camry and Toyota Solara cooling systems

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. This molded hose is intended for the pipe to throttle body position on the listed Toyota Camry and Toyota Solara applications, so match the original path carefully to avoid kinks or tension at the connections. Inspect adjoining pipes, clamps, and throttle body fittings for wear before installing the replacement hose.

Quality Assurance
