Removal and Installation EBS008QU
CAUTION:
q Be sure to use genuine NISSAN exhaust system parts or equivalents which are specially designed F
for heat resistance, corrosion resistance, and shape.
q Perform the operation with the exhaust system fully cooled down because the system will be hot
just after the engine stops.
G
q Be careful not to cut your hand on the insulator edges.

EXHAUST SYSTEM (QR25DE)
q If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator,
remove them. A
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 gas leak- EX
age.
q Temporarily tighten the exhaust manifold side mounting nuts and the vehicle side mounting bolts. Check
each part for unusual interference, and then tighten them to the specified torque. C
q When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left direc-
tions.
q Insert the seal bearing in the direction as shown. Tighten the D
mounting bolt with the big end of the spring facing the flange.
CAUTION:
Tighten the mounting bolt without causing interference with E
the flange.

Inspection After Installation EBS008QV
q With the engine running, check exhaust tube joints for gas leakage and abnormal noise. H
q 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.
