Gates Molded Heater Hose 19500

The Gates Molded Heater Hose 19500 is an OEM-style coolant hose built for tight engine bays and factory routing. Its molded shape helps match original hose paths on select Chevrolet Cobalt, Pontiac G5, and Pontiac Pursuit applications.

Key Features

  • Factory-molded design for a direct OE-style fit
  • EPDM construction for coolant, water, and air service
  • Small inside diameters: 15 mm at one end and 19 mm at the other
  • Centerline length of 353 mm (13.9 in)
  • Approved for marine applications
  • Fits heater-to-thermostat and heater-to-engine routing on listed vehicles

Product Details

Gates Molded Heater Hose 19500 is part of the Molded Heater Hose line, which focuses on factory-shaped hoses for modern vehicles with compact engine compartments. This hose is formed to follow the original routing more closely than straight hose, helping maintain proper fit in confined spaces. It is made from EPDM and is specified for coolant, water, and air applications, with marine approval noted by the manufacturer.

This part cross-references Dayco 87904 for the same application. The Gates 19500 is a direct-fit replacement for select 2005-2010 Chevrolet Cobalt, Pontiac G5, and Pontiac Pursuit heater hose locations.

What It Helps Address

  • Cracked or deteriorated heater hose material
  • Coolant leaks at a molded hose section
  • Improper hose routing in tight engine compartments
  • Heat-related hose hardening or swelling
  • Loss of heater circuit flow from a damaged hose

Installation Notes

  • Verify end diameters and centerline length before installation.
  • Match the hose to the listed routing: heater to thermostat or heater to engine.
  • Inspect adjoining fittings, clamps, and thermostat housing surfaces for wear before reuse.
  • Confirm the hose follows the original molded path without twisting or kinking.

Quality Assurance

Gates manufactures this hose as an OEM-style molded replacement for the listed applications. The molded construction and EPDM material support consistent fitment and service in coolant-system use.
