Gates 18748 Molded Heater Hose Overview

The Gates 18748 molded heater hose is an OEM-style coolant hose formed for tighter engine bays and smaller routing spaces. It is built from EPDM and shaped to follow the factory path for a clean, direct replacement in HVAC heater hose service.

Compatible With Ford Explorer, Mercury Mountaineer, Honda Civic, Acura EL, and other listed applications, this molded heater hose supports coolant, water, and air transfer. The Gates Molded Heater Hose line focuses on factory-shaped routing for vehicles where a straight hose will not match the original layout.

Key Features

  • Factory-molded shape for OE-style routing
  • EPDM construction for heater and coolant service
  • Small inside diameters: 16 mm (.62 in) and 19 mm (.75 in)
  • Centerline length: 315 mm (12.4 in)
  • Approved for coolant, water, air, and marine applications
  • Direct-fit style for compact engine compartments

Detailed Description

Gates part number 18748 is a molded HVAC heater hose built to match the contours needed in modern and older engine layouts. Its factory-molded design helps maintain proper hose routing where space is limited, including applications such as 2006 Ford Explorer heater to valve, 2006 Mercury Mountaineer heater to valve, and 1999-2000 Honda Civic heater to pipe. It also appears in fitments for Acura EL and multiple Ford van and Chrysler-era heater hose routes.

This molded heater hose is part of the Gates Molded Heater Hose product line, which is aimed at OE-style replacement where the original hose shape matters as much as the hose size. Part number 18748 is also cross-referenced by Continental 63106 for the same application.

Common Problems This Hose Can Address

  • Cracked or leaking heater hose at the factory bend
  • Incorrect hose routing after a previous repair
  • Restricted coolant flow caused by a deteriorated hose
  • Fitment issues in tight engine compartments
  • Replacement needs for molded heater hose service on older and newer vehicles

Installation Notes and Tips

  • Verify end sizes and centerline length before installation: 16 mm and 19 mm ends with a 315 mm centerline length.
  • Match the hose to the exact heater hose position listed for the vehicle, such as heater to valve, heater to pipe, or valve to engine.
  • Check whether the application notes mention A/C, serpentine belt routing, or cut-to-fit requirements.
  • Inspect adjoining pipes, valves, and clamps for wear before installing the new hose.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement for factory routing and fit. The EPDM construction and molded profile support dependable service in coolant, water, air, and marine applications.
