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.

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.
