Detailed Product Description

The Gates Molded Heater Hose 18018 is engineered to meet the specific requirements of the Lexus CT200h heating and ventilation system. Its EPDM construction offers excellent resistance to heat, ozone, and automotive fluids, making it suitable for long-term use in demanding engine environments. The molded design ensures the hose maintains its shape and fits precisely between connection points, reducing the risk of leaks or improper installation. With a centerline length of 30.3 inches (770 mm), this hose matches OEM specifications for seamless integration into your vehicle's HVAC system.

This part features two different inside diameters on each end—0.37 inches (9 mm) on one side and 0.44 inches (11 mm) on the other—to accommodate specific connection points within the Lexus CT200h. The absence of quick connect fittings means it is designed for traditional hose clamp connections, ensuring a secure and reliable seal.
