Common Faults & Troubleshooting

1. Low Power, Poor Acceleration, Hard Start

• Cause：Clogged filter, excess water, air in fuel line
• Fix：Drain water; check fuel pressure (<0.3MPa = clogged); bleed air
• Action：Replace C5335858ZZ; inspect lines & seals

2. Rough Idle, Black Smoke, High Fuel Consumption

• Cause：Filter failure, contaminated injectors, poor atomization
• Fix：Inspect injectors; replace filter; test pressure
• Action：Replace filter; clean/replace injectors if needed

3. Fuel Leakage at Filter Head

• Cause：Worn seal, under-torque, deformed housing
• Fix：Check O-ring; torque 35–45N·m; replace filter
• Action：Replace filter + seal; torque correctly

4. Short Filter Life, Frequent Clogging

• Cause：Poor fuel quality, failed pre-filter, dirty tank
• Fix：Test fuel cleanliness; replace pre-filter; clean tank
• Action：Use clean diesel; replace pre-filter; drain water regularly
