FAQ

Q: How can I confirm this nozzle (093400-0090) fits my engine?
A: The most reliable method is to remove your existing injector nozzle and compare the part number stamped on its side. It should match 093400-0090 or DN40SDND32. You can also check your engine service manual for the fuel injector specifications. If you are unsure, please contact us with your engine model or vehicle VIN for verification.

Q: What is the recommended installation procedure for this injector nozzle?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the injector bore in the cylinder head. 2) Replacing the copper washer or sealing gasket (not included). 3) Lubricating the nozzle body with clean diesel fuel before insertion. 4) Tightening the injector clamp or nut to the manufacturer’s specified torque to avoid distortion. 5) Bleeding the fuel system of air before starting the engine.

Q: What is the typical lifespan of this injector nozzle, and how can I maintain it?
A: The lifespan depends heavily on fuel quality and engine operating conditions. In well-maintained engines using clean, high-quality diesel, these nozzles can last 50,000 to 100,000 kilometers. To extend life, always use proper fuel filters, change them on schedule, and avoid running the engine on low-quality or contaminated fuel. Symptoms of a failing nozzle include rough idling, black smoke, increased fuel consumption, and loss of power.
