  Genuine OEM Nissan Throttle Body Coolant Hose — Part # 14056-AL515

  Replace your cracked or leaking coolant hose with the factory-correct unit for the VQ35DE engine. This genuine OEM Nissan water hose (#5 in the cooling circuit) routes coolant through the throttle body — keeping the throttle body at proper operating temperature and preventing icing in cold weather. Exact factory fit, correct diameter, correct length, and factory-grade rubber compound.

  Part Details:

  ⚠️ Production Date & Transmission Note: This hose fits the 350Z with the VQ35DE engine to 11/2006 — covering both automatic and manual transmission variants including Rev-Up engine applications. Models built after November 2006 use the updated VQ35HR engine and require a different hose. Always confirm your production date and engine code with your VIN before ordering.

  • 2003–2007 Nissan 350Z (VQ35DE, all trims — to 11/2006)
  • Infiniti G35 (VQ35DE applications — confirm VIN)

  Always confirm fitment using your VIN and production date before purchasing.

  Why buy OEM? Throttle body coolant hoses are subjected to constant heat cycles and must maintain flexibility without cracking or swelling. Aftermarket hoses for Z-car applications are frequently generic sizes that don't fit snugly at the throttle body ports — leading to coolant seepage and air pockets in the cooling system. The genuine Nissan hose is molded to exact factory dimensions for a secure, leak-free fit.

  Symptoms this part fixes:

  • Coolant leak near the throttle body
  • Visible cracking, hardening, or swelling of the existing hose
  • Low coolant with no obvious external leak
  • Coolant smell from the engine bay
  • Rough idle or poor throttle response in cold weather due to throttle body icing
