FAQ

Q1: How do I confirm this nozzle fits my specific injector?
A: First, locate the part number on your current injector nozzle. Compare it directly with our listed numbers: 093400-5571, 105007-1260, or DN4PD57. If your part matches, it is the correct replacement. If you are unsure, contact our technical support team with your engine model and current injector part number for verification.

Q2: What are the signs that my injector nozzle needs replacing?
A: Common symptoms include rough engine idling, increased fuel consumption, black smoke from the exhaust, a loss of engine power, and difficulty starting the engine. These issues often stem from a worn or clogged nozzle that cannot properly atomize the fuel.

Q3: Is professional installation required for this part?
A: Yes, we strongly recommend installation by a qualified diesel mechanic. Replacing an injector nozzle requires specific tools and knowledge to ensure proper cleaning of the injector body, correct torque settings, and to prevent contamination of the fuel system. Improper installation can lead to poor performance or engine damage.
