III. Critical Technician Notes (MUST-DO)

1. Clean Installation: Ultrasonically clean nozzle before installation to prevent contamination.
2. Sealing Components: Always replace copper crush washers, O-rings, and injector seals.
3. Injector Mounting: Use new clamp or stretch bolts; follow Renault OEM torque and alignment specifications.
4. Post-Installation Testing: Perform leak-back and test-bench spray pattern verification.
5. Calibration / Coding: If required, use Renault or BOSCH diagnostic tools to code or calibrate the injector.
6. Fuel System Quality: Replace fuel filters and ensure fuel is clean and water-free; DV6 / F9Q injectors are highly sensitive.
7. Storage & Handling: Keep nozzles in a dry, dust-free environment; avoid impacts or dropping.
8. Long-Term Monitoring: Check injector performance (leak-back, idle, load response) after installation to detect early nozzle wear.
9. Common Fault Symptoms to Monitor: Hard cold start, rough idle, black smoke, loss of power, or excessive fuel return flow.
