Keep coolant moving to your heater core with the Gates HVAC Heater Hose 19897, a premium factory-molded hose that drops in as a direct-fit replacement at the heater inlet on the 2007-2008 Nissan Maxima [V6-3.5L]. This small I.D., OEM-style molded hose is shaped to fit today's smaller, tighter-fitting engine compartments and carries coolant, water, and air; it is also approved for marine applications.
- Molded OEM-style construction: Factory-molded to route cleanly in tight engine bays, with all the quality features of Gates molded coolant hose and built similar to OEM specifications.
- EPDM build: EPDM tube, synthetic fiber knit reinforcement, and EPDM cover, engineered to resist electrochemical degradation — the leading cause of hose failure.
- Rated and specced: Meets SAE 20R3 Type EC Class D-1 and D-2 specifications, with a temperature range of -40°F to 275°F (-40°C to 135°C).
Gates recommends replacing the hose clamps each time a new coolant hose is installed. Caution: do not use for fuel or oil transfer applications. Country of origin: United States.
