FAQ

Q1: How do I verify if nozzle 04281859 fits my engine?
A: We recommend checking your existing injector for the stamped part number (DOP152P522-3898). If it matches, this is a direct replacement. If not, please provide your engine model (e.g., 6HK1, 4JJ1) or injector assembly number to our sales team for cross-verification.

Q2: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Ensure the injector bore is clean and free of debris. Lubricate the nozzle with clean diesel fuel before insertion. Always replace the copper sealing washer (not included) and tighten to the manufacturer’s specified torque to prevent leakage and ensure proper heat transfer.

Q3: Can I use this nozzle in a common-rail system?
A: This nozzle is designed for high-pressure applications. While it fits many Bosch-type injector bodies, we strongly advise checking the operating pressure range of your specific fuel system. For modern common-rail systems operating above 2000 bar, please consult our team to confirm compatibility to avoid performance issues.
