Gates 18763 HVAC Heater Hose - Heater To Water Pump

Gates 18763 Molded Heater Hose Overview

Gates 18763 is a factory-molded HVAC heater hose built for tight engine bays and OE-style routing. It is made from EPDM and is shaped to match the heater-to-water-pump path used on select Ford Escort and Mercury Tracer applications.

The Gates Molded Heater Hose line focuses on small I.D. coolant routing where a straight hose will not follow the original path cleanly. This molded design supports coolant, water, and air transfer, and it is also approved for marine applications.

Key Features

• Factory-molded, OE-style hose for precise routing
• EPDM construction for HVAC heater hose service
• Small I.D. design for tighter engine compartments
• End inside diameters: 16 mm (.62 in) and 22 mm (.85 in)
• Centerline length: 597 mm (23.5 in)
• Direct replacement style for heater-to-water-pump routing

Detailed Description

This Gates molded coolant hose is engineered for applications where the hose must bend around nearby components without kinking or collapsing. For 1991-1996 Ford Escort and 1991-1996 Mercury Tracer models, it serves the heater to water pump connection and follows the original molded path for a cleaner installation. If you are searching for a Ford Escort heater hose or Mercury Tracer heater hose by part number, Gates 18763 is a direct OE-style option.

This part cross-references Four Seasons 86062 and Continental 63057 for the same application.

What It Helps Address

• Cracked or leaking heater hose routing at the water pump connection
• Collapsed or softened hose sections from heat and age
• Poor fitment from universal straight hose replacements
• Restricted coolant flow caused by incorrect hose shape
• Service replacement needs on Ford Escort and Mercury Tracer heater circuits

Installation Notes and Tips

• Verify the hose path against the original molded routing before installation.
• Inspect adjoining heater and coolant connections for wear, corrosion, or residue.
• Confirm end diameters and centerline length match the vehicle routing before clamping.
• Use the hose on the specified heater-to-water-pump position only.

Quality Assurance

Gates is known for OE-style hose construction and molded coolant routing solutions used in automotive, coolant, water, air, and marine service applications. Part number 18763 is built to match the shape and dimensions needed for the listed Ford Escort and Mercury Tracer fitments.
