Gates 18758 Molded Heater Hose

The Gates 18758 Molded Heater Hose is a precision-formed, vehicle-specific heater hose engineered to replace the original equipment heater hose in your cooling and heating system. Designed to exact OEM specifications, this molded hose maintains its pre-shaped form for a direct, rattle-free fit — eliminating the twisting and kinking that can occur with straight hose segments.

Gates manufactures this heater hose from a high-quality EPDM (ethylene propylene diene monomer) rubber compound that resists heat, coolant degradation, and electrochemical deterioration (ECD) — one of the leading causes of hose failure. The inner tube is reinforced to handle the pressure and temperature demands of modern engine cooling systems.

Key Features:

• Pre-molded, vehicle-specific shape for direct OEM replacement
• EPDM rubber construction resists heat, ozone, and coolant chemicals
• Electrochemical deterioration (ECD) resistant inner liner
• Maintains shape under high heat and pressure cycles
• Designed for precise, leak-free connections at heater core and engine ports
• Meets or exceeds original equipment standards

As a trusted name in belt and hose technology since 1911, Gates delivers reliable, long-lasting performance in every hose. The 18758 is a direct-fit solution that simplifies installation and restores proper coolant flow to the vehicle's heater core.
