What does the Dorman 626-610 heater hose assembly fit?
It is a direct-fit inlet heater hose assembly for the 2005-2019 Nissan Frontier, 2005-2012 Nissan Pathfinder, and 2005-2015 Nissan Xterra. Check the Buyer's Guide tab to confirm your engine.
Why does the original heater hose assembly fail?
Original-equipment units often crack at the plastic Y-connector, which can cause a coolant leak. This Dorman OE FIX replaces that plastic connector with an aluminum one for added durability.
Does this Dorman heater hose assembly come with clamps?
Yes. The hoses come with the necessary clamps for installation, so it is a complete replacement for the inlet-side assembly.
Is this the correct part for a 2005-2019 Nissan Frontier heater hose outlet leak?
This assembly is cataloged for the inlet position. Confirm whether your leak is on the inlet or outlet side, and verify fitment for your 2005-2019 Nissan Frontier in the Buyer's Guide tab before ordering.
What makes this an OE FIX part?
Dorman's OE FIX line addresses a known weakness in the original design. Here, the plastic Y-connector is upgraded to aluminum to help prevent the cracking that affects the factory part.
