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 procedures 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 edge.
^ Always replace the exhaust gaskets with new ones for installation.
^ If any insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, clean and inspect them.
^ When installing the insulator avoid large gaps or interference between the insulator and the exhaust pipe.
^ Remove any deposits from the sealing surface of each connection. Connect them securely to avoid exhaust gas leakage.
^ Temporarily tighten the mounting nuts on the exhaust manifold side and the mounting bolts on the vehicle side. Check each part for interference with other components, and then tighten the nuts and bolts to specification.
^ When installing each mounting rubber, avoid twisting or any over extension in up/down and right/left directions.

Inspection After Installation
^ With the engine running, check the exhaust tube joints for exhaust gas leaks and unusual noises.
^ 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.
