Product Details

The Gates Molded Heater Hose line is built around factory-molded, OE-style fitment for vehicles with smaller, tighter engine compartments. Part number 18849 is formed to follow the original hose path and is specified for coolant, water, and air applications. It is a direct service option for HVAC heater hose replacement on applications such as the Mitsubishi Eclipse heater inlet, Mitsubishi Galant heater inlet, and Honda Accord or Honda Prelude valve-to-engine routing. This part cross-references Dayco 87688 for the same application.

Common Problems It Can Address

• Cracked or heat-aged heater hose material
• Coolant seepage at a molded hose section
• Poor hose routing in tight engine compartments
• Restricted heater circuit flow from a deteriorated hose
• Service replacement for worn HVAC heater inlet hose routing

Installation Notes and Tips

• Verify end diameters and centerline length before installation.
• Match the molded shape to the original hose routing on the vehicle.
• Inspect clamps, fittings, and adjoining pipes for wear before reassembly.
• Confirm the hose path clears nearby components in compact engine bays.
