Gates HVAC Heater Hose P/N:12318
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.
Gates recommends installing new clamps each time a coolant hose is replaced. Do not use for fuel or oil transfer applications.
