  ⚠️ Engine Note — 2.5L 4-Cylinder Only: This pulley fits the 2.5L QR25DE 4-cylinder Frontier only. The 4.0L V6 VQ40DE Frontier uses a different fan and water pump pulley. Always confirm your engine with your VIN before ordering.

  Compatible Vehicles:

  • 2005–2019 Nissan Frontier (2.5L QR25DE — S, SE, SV, XE trims)

  Always confirm fitment using your VIN before purchasing.

  Why buy OEM? Aftermarket fan pulleys are frequently cast from inferior aluminum with imprecise bore tolerances — causing belt misalignment, accelerated belt wear, and vibration that loads the water pump bearing. The genuine Nissan pulley is machined to exact factory specifications for correct belt tracking and smooth operation throughout its service life.

  When you need this part:

  • Water pump replacement — always replace the pulley with the pump
  • Pulley cracked, corroded, or bent from impact or age
  • Belt slipping or wearing unevenly — caused by a warped or damaged pulley
  • Vibration from the front of the engine traced to the fan pulley
  • Preventive replacement during timing chain or serpentine belt service

  Ships fast from Walser Nissan Wayzata — an authorized Nissan dealership. Message us your VIN and we'll confirm fitment before you buy.

• Condition: New
