Product Details

Gates 19878 is a molded HVAC heater hose made to match the routing needs of modern engine compartments. The EPDM material is used for durability in coolant service, while the molded profile helps maintain proper hose alignment at the heater inlet or engine-to-heater inlet tube connection. This part cross-references Continental 64395 for the same application. For buyers searching for a Nissan Frontier heater inlet hose, Nissan Xterra heater inlet hose, or Nissan Pathfinder heater inlet hose, this molded hose provides the correct style and dimensions for those listed applications.

What It Helps Fix

• Cracked or leaking heater inlet hose connections
• Improper hose routing in tight engine compartments
• Coolant loss at the heater inlet or engine-to-heater inlet tube
• Hose collapse or fitment issues from using a straight universal hose
• Service replacement needs on select Nissan Frontier, Xterra, Pathfinder, and Suzuki Equator models

Installation Notes

Verify the hose path, end diameters, and molded shape against the original part before installation. Confirm the vehicle position listed for your application, including heater inlet or engine-to-heater inlet tube, and inspect adjoining clamps, tubes, and sealing surfaces for wear before reassembly. This part is listed for 2005-2013 Nissan Frontier heater inlet, 2014-2018 Nissan Frontier engine to heater inlet tube, 2005-2015 Nissan Xterra heater inlet, 2007-2012 Nissan Pathfinder heater inlet, and 2009-2012 Suzuki Equator heater inlet applications.
