III. Critical Technician Notes (MUST-DO)

1. Injector Coding: After replacing the nozzle, always re-enter or verify the injector correction code (IMA/ISA) in the ECU.
2. Sealing Components: Replace copper washers, return line seals, and O-rings every time the injector is removed.
3. Clamp Bolts: Use new injector clamp bolts — these are stretch bolts and must not be reused.
4. Clean Installation: Ensure a completely clean work environment; even small contamination can damage CR injectors.
5. System Verification: Perform leak-back test, rail pressure evaluation, and pilot injection calibration after installation.
