Route coolant to the heater core and keep the HVAC loop sealed with the Gates HVAC Heater Hose 51900, a Premium Modular Coolant Hose that drops in as a direct-fit replacement for the 2013-2020 Ford Escape and 2015-2019 Lincoln MKC (see the Buyer's Guide tab for engine-level fitment). Cataloged for the heater, left-side position, this modular assembly is built to specific applications with OEM-exact integrated components such as quick-connectors, branch connectors/tees, sensors and restrictors.

  • Modular OE-style assembly: manufactured with OEM-exact hose components (quick connects, branch connectors/tees, sensors) to match specific applications.
  • EPDM construction: EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover.
  • Engineered materials: specifically engineered to resist collapse under vacuum and to resist electrochemical degradation, a leading cause of hose failure.
  • Rated specs: meets SAE 20R3 EC Class D1 under 25mm (1 in.) ID and SAE 20R4 EC Class D1 for 25mm (1 in.) ID and over; temperature range -40°F to +257°F (-40°C to +125°C).

Gates recommends replacing the clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications.
