FAQ

Q1: Is this part a complete injector or just the nozzle tip?
A: This is a standalone injector nozzle tip (Part: DLLA150P30). It does not include the injector body, holder, or other components. It is designed for installation into a compatible injector assembly.

Q2: How do I verify if this nozzle fits my engine?
A: Check the existing part number on your old nozzle. If it matches 0433171031, 0 433 171 031, or DLLA150P30, it is a direct fit. Also confirm that your injector body uses a P-Type nozzle with a 150° spray angle. If unsure, please provide your engine model (e.g., 4HK1, 6WG1) for cross-reference.

Q3: What is the installation process and recommended maintenance?
A: Installation should be performed by a qualified diesel technician. Ensure the injector body and sealing surfaces are clean. Replace the nozzle retaining nut and heat shield if required. After installation, bench-test the injector for opening pressure and spray pattern. Regular maintenance includes replacing nozzles every 200,000-300,000 km or as per engine manufacturer guidelines to prevent performance loss.
