Exhaust system check (30,000 km) (Nissan Sunny B13)

1. Check the condition of the exhaust system, starting from the engine to the final section. Perform the check on a cold engine, at least 1 hour after the trip. For the check, it is best to lift the engine to ensure unimpeded access to all parts of the system.

2. If you don't have a lift, raise the vehicle and place it on stands.

3. Check the exhaust pipes and connections for signs of exhaust leakage, severe corrosion and mechanical damage. Make sure all brackets and supports for the exhaust pipes are securely fastened and intact. Exhaust leaks can usually be detected by a soot deposit.

4. Loud knocking sounds from the exhaust system are usually caused by poorly secured exhaust pipes on brackets and supports. Shake the pipes with mufflers. If the pipes and mufflers come into contact with suspension parts or the underbody, replace the fastening parts or, if possible, separate the pipes and rotate them relative to each other to ensure sufficient distance from other parts.
