Exhaust System: Service and Repair

Removal and Installation

CAUTION:
^ Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat resistance, corrosion resistance, and shape.
^ Perform the procedure with the exhaust system fully cooled down because the system will be hot just after the engine is turned off.
^ Be careful not to cut your hand on the insulator edges.
^ If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, clean and inspect the insulator.
^ When installing the insulator avoid large gaps or interference between the insulator and each exhaust pipe.
^ Remove deposits from the sealing surface of each connection. Connect them securely to avoid exhaust gas leaks.
^ Temporarily tighten the exhaust manifold side mounting nuts and the vehicle side mounting bolts. Check each part for any interference, and then tighten the nuts and bolts to specification.
^ When installing each mounting rubber, avoid twisting or excessive extension in up/down and right/left directions.
^ Tighten the mounting bolts without causing interference with the flange.





^ Insert the seal bearing in the direction as shown. Tighten the mounting bolt with the big end of the spring facing the flange as shown.

Inspection After Installation
^ With the engine running, check the exhaust tube joints for exhaust gas leaks and abnormal noise.
^ Check that the mounting brackets and mounting insulators are installed properly and free from excessive stress. Improper installation could result in excessive noise, leaks, and vibration.
