  Description:

  Genuine OEM Nissan Engine Coolant Water Inlet Manifold Pipe — Part # 14053-JK21C

  Replace your leaking, cracked, or damaged rear coolant inlet pipe with the factory-correct unit for Nissan's VQ35HR and VQ37VHR V6 platforms. This genuine OEM pipe routes coolant into the rear of the engine's intake manifold — a critical coolant circuit component on the VQ platform that is commonly found leaking on higher-mileage engines due to the heat cycling of the aluminum pipe and plastic end fittings. Direct factory fit, correct end connections, correct routing.

  Why buy OEM? Aftermarket coolant inlet pipes for the VQ platform are frequently made from inferior plastic or aluminum alloys that crack sooner than the factory unit. The genuine Nissan pipe is the only replacement manufactured to the VQ engine's exact coolant circuit specifications — correct wall thickness, correct end fitting sealing surfaces, and correct material for long-term heat resistance.

  Symptoms this part fixes:

  • Coolant leak from the rear of the engine — often visible as a drip near the firewall
  • Low coolant with no obvious front-of-engine leak
  • Coolant smell from the engine bay when warmed up
  • Visible coolant residue or staining on the rear of the intake manifold area
  • Overheating caused by coolant loss from this pipe
