Keep coolant moving to the heater core with the Gates heater hose (P/N 51561), a premium modular coolant hose that drops in as a direct-fit replacement for the 2006-2010 Mazda 5 (see the Buyer's Guide tab for the full engine list). Gates leads the modular assembly coolant hose segment, building each hose to specific applications with OEM-exact integrated components — quick connects, branch connectors/tees, sensors and restrictors — so it matches the original assembly. It is cataloged for the heater (lower) position, and is also listed as an hvac heater hose.

  • EPDM construction: EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover.
  • Collapse- and degradation-resistant: specifically engineered materials resist collapse under vacuum and resist electrochemical degradation, the leading cause of hose failure.
  • SAE rated: meets SAE 20R3 EC Class D1 under 25mm (1 in.) ID and SAE 20R4 EC Class D1 for 25mm (1 in.) ID and over.
  • Wide temperature range: rated from -40°F to +257°F (-40°C to +125°C).

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