FAQ

Q: How do I verify that the DLLA153PN203 nozzle fits my engine?
A: Please check your original injector body or nozzle for the stamped part number (105017-2030 or DLLA153PN203). This nozzle is commonly used in Isuzu 4HK1 and 6HK1 engines, as well as various Mitsubishi and Hyundai diesel models. If unsure, contact us with your engine model and serial number for confirmation.

Q: What is the recommended installation procedure?
A: Ensure the nozzle seat and injector body are clean and free of debris. Lubricate the nozzle lightly with clean diesel fuel before installation. Tighten the retaining nut to the manufacturer’s specified torque (typically 70-90 Nm). Do not overtighten. Always replace copper washers and seals for a leak-free fit.

Q: How can I maximize the lifespan of this injector nozzle?
A: Use high-quality diesel fuel with proper filtration. Replace fuel filters regularly. Avoid running the engine with contaminated fuel or water ingress. For optimal performance, we recommend replacing nozzles in sets (e.g., for a 6-cylinder engine, replace all 6 at once) to ensure balanced fuel delivery.
