Exhaust System: Service and Repair

Removal and Installation

CAUTION:
^ Be sure to use genuine NISSAN exhaust system parts or equivalents which are specially designed for heat resistance, corrosion resistance, and shape.
^ Perform the operation with the exhaust system fully cooled down because the system will be hot just after the engine stops.
^ Be careful not to cut your hand on the insulator edge.

CAUTION:
^ Always replace exhaust gaskets with new ones when reassembling.
^ If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, remove them.
^ 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 gas leakage.
^ Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle side. Check each part for unusual interference, and then tighten them to the specified torque.
^ When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/ left directions.

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