Product Details

Gates Molded Heater Hose 18399 is built for direct routing in smaller, tighter-fitting engine compartments where a formed hose is needed to maintain the correct path and connection points. This molded heater hose is listed for 1998-2002 Honda Accord thermostat to pipe-1 applications, making it a fitment-specific choice for Honda Accord cooling system service. The Gates Molded Heater Hose line focuses on OE-style molded coolant hose construction for vehicles that require precise hose geometry rather than universal straight hose lengths.

Common Issues It Can Address

  • Cracked or hardened heater hose material
  • Coolant seepage at a formed hose section
  • Incorrect hose routing in a tight engine bay
  • Loss of heater circuit flow from a deteriorated hose
  • Service replacement for a thermostat-to-pipe hose on Honda Accord models

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. Confirm the thermostat-to-pipe routing on the vehicle and inspect adjoining clamps, pipe ends, and sealing surfaces for wear or corrosion before reassembly. This hose is listed for 1998-2002 Honda Accord thermostat to pipe-1 applications, so match the original formed shape to the vehicle layout before final installation.

Quality Assurance
