EXHAUST SYSTEM (QR25DE)
CAUTION:
q Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat A
resistance, corrosion resistance, and shape.
q Perform the procedure with the exhaust system fully cooled down because the system will be hot
just after the engine is turned off. EX
q Be careful not to cut your hand on the insulator edges.
q If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insu-
lator, clean and inspect the insulator. C
q When installing the insulator avoid large gaps or interference between the insulator and each
exhaust pipe.
q Remove deposits from the sealing surface of each connection. Connect them securely to avoid D
exhaust gas leaks.
q 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. E
q When installing each mounting rubber, avoid twisting or excessive extension in up/down and
right/left directions.
q Tighten the mounting bolts without causing interference with the flange. F
q 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.

q With the engine running, check the exhaust tube joints for exhaust gas leaks and abnormal noise.
q 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. K

EXHAUST SYSTEM (VQ35DE)
CAUTION:
q Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat
resistance, corrosion resistance, and shape.
q Perform the procedures with the exhaust system fully cooled down because the system will be hot
just after the engine is turned off.
q Be careful not to cut your hand on the insulator edge.
q Always replace the exhaust gaskets with new ones for installation.
q If any insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insu-
lator, clean and inspect them.
q When installing the insulator avoid large gaps or interference between the insulator and the
exhaust pipe.
q Remove any deposits from the sealing surface of each connection. Connect them securely to
avoid exhaust gas leakage.
q 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.
q When installing each mounting rubber, avoid twisting or any over extension in up/down and right/
left directions.
Inspection After Installation EBS00EW2
q With the engine running, check the exhaust tube joints for exhaust gas leaks and unusual noises.
q 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.
