FAQ

Q1: Will this injector fit my specific engine model?
A: This injector is designed for universal application in common rail diesel systems. However, we recommend verifying the OEM numbers (0445120212, 0445120007, etc.) against your engine’s specifications. If you are unsure, please provide your engine serial number for cross-referencing.

Q2: What is the recommended installation procedure?
A: Installation should be performed by a qualified technician. Ensure the fuel system is depressurized, clean the mounting surface, and replace sealing washers. Torque to manufacturer specifications (typically 25-30 Nm). After installation, prime the system and check for leaks before starting the engine.

Q3: How can I ensure long service life from this injector?
A: Use high-quality diesel fuel with proper filtration. Replace fuel filters regularly and avoid running the engine on low fuel. Periodic cleaning of the injector nozzle (every 500 hours of operation) can help maintain optimal performance. Always use genuine sealing components during installation.
