Gates Molded Heater Hose 19629

The Gates 19629 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. With a 19 mm (0.75 in) inside diameter at both ends and a 20.1 in (511 mm) centerline length, it supports heater, coolant, water, and air routing in the original molded shape.

Key Features

  • Gates Molded Heater Hose line for factory-style replacement routing
  • Part number 19629 for direct reference and catalog matching
  • EPDM construction for coolant-system service
  • 19 mm (0.75 in) inside diameter at both ends
  • 20.1 in (511 mm) centerline length
  • Molded profile for compact engine bay routing
  • Approved for marine applications

Product Details

This Gates heater hose is formed to follow the original hose path in vehicles with limited clearance, helping maintain proper routing between the heater core and pipe connections. The molded EPDM construction is suited for coolant transfer and related fluid or air applications, while the factory-shaped design supports a cleaner installation than a universal straight hose. Gates 19629 is a practical OE-style replacement for older Ford Tempo and Mercury Topaz heater hose applications, including Canada-market and dealer-installed or factory A/C configurations listed in the fitment data.

This part cross-references Dayco 88374 for the same application.

Installation Notes

Verify the hose path, end inside diameter, and centerline length against the original part before installation. Because this is a molded hose, correct orientation matters for proper clearance around nearby components in the heater circuit. Confirm whether the vehicle is equipped with A/C and match the listed heater-to-pipe position exactly for Ford Tempo and Mercury Topaz applications.

Quality Assurance

Gates is known for OE-style hose construction and application-specific fitment in cooling-system service parts. The 19629 molded heater hose follows the brand’s molded heater hose line for vehicles that require a shaped replacement rather than a universal hose.
