Gates 19684 Molded Heater Hose Overview

The Gates 19684 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path is required. It is made from EPDM and measures 15.5 inches centerline length with 0.72-inch inside diameter ends for a precise fit in the heater circuit.

Compatible With 1992-1994 Ford Tempo and 1992-1994 Mercury Topaz heater-to-pipe applications, this molded heater hose supports coolant, water, and air transfer. The Gates Molded Heater Hose line focuses on factory-shaped routing for vehicles that need a formed replacement rather than a universal straight hose.

Key Features

  • Gates part number 19684 molded heater hose
  • OEM-style factory-molded shape for tighter engine bays
  • EPDM construction for heater and coolant service
  • 0.72-inch inside diameter at both ends
  • 15.5-inch centerline length for formed routing
  • Approved for marine applications

Detailed Product Description

Gates 19684 is a molded coolant hose designed to follow the original routing used in compact engine compartments. Its formed profile helps maintain proper hose alignment in heater-to-pipe service on the Ford Tempo and Mercury Topaz, while the EPDM material is suited for coolant, water, and air applications. If you are replacing a worn or hardened heater hose on a 1992-1994 Ford Tempo or 1992-1994 Mercury Topaz, this molded replacement matches the application-specific shape needed for a clean installation.

This part cross-references Dayco 86063 for the same application.

Common Problems This Hose Can Address

  • Cracked or brittle heater hose material
  • Coolant seepage at a formed hose section
  • Improper routing from a collapsed or misshaped hose
  • Restricted heater flow caused by hose deterioration
  • Replacement needs for heater-to-pipe connections on Ford Tempo and Mercury Topaz models

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Confirm the vehicle application as 1992-1994 Ford Tempo or 1992-1994 Mercury Topaz, heater to pipe-1, and inspect adjoining pipes and clamps for wear before transferring the hose into service. Because this is a molded hose, align it to the original path rather than forcing a straight installation.

Quality Assurance

Gates is known for producing application-specific hose components that follow OE-style fitment requirements. The 19684 molded heater hose is built to the listed dimensions and formed shape for the confirmed vehicle applications.
