FAQ

Q: How do I confirm this nozzle (DLLA150SN859) fits my engine?
A: Please compare the part number stamped on your old injector nozzle with our list: DLLA150SN859, 105015-8590, 1050158590, 8590, or 150SN859. If there is a match, it is a direct fit. If you are unsure, please contact us with your original part number and engine model for verification.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Ensure the nozzle seating surface is clean and free of debris. Tighten the retaining nut to the manufacturer’s specified torque setting. It is highly recommended to replace the nozzle washers and seals at the same time to prevent leaks.

Q: What is the typical lifespan of this nozzle?
A: The lifespan depends on fuel quality and engine maintenance. Under normal operating conditions with clean fuel and proper injection system maintenance, this high-speed steel nozzle can last 80,000 to 150,000 km or more. Using poor quality fuel or failing to replace fuel filters regularly can significantly reduce its lifespan.
