Chapter XII Exhaust System
Section I General
Attention:
It is necessary to keep a sufficient distance between the exhaust system assembly and
the floor so as to protect the floor base from being overheated and protect the heat insulation and
trimming materials in the passenger compartment from being damaged.
When checking or replacing the exhaust system assembly, you need to keep a sufficient distance
between the exhaust system assembly and the floor so as to protect the floor base from being
overheated and protect the heat insulation and trimming materials in the passenger compartment from
being damaged.
Check the overall exhaust system and the body surface around it as well as the rear compartment cover
for any crack, damage, missing or displaced parts, and check them for separated junction, eyelet, loose
connections or other damaged that may result in exhaust leakage into the rear compartment or the
passenger compartment. If there is dust or water in the rear compartment, it means that there is a
problem in this area. Any malfunction should be eliminated immediately.
The specific structure of the exhaust system varies depending on the vehicle model, so before
maintenance, you should well knew its structure for the model involved and then take corresponding
measures.

Section II On-board Maintenance
The explosion sound and vibration noise generally occur when some parts are not well centered. For the
adjustment of the exhaust system, first unscrew all bolts and nuts until all parts are well centered, and
then screw down them from front to rear.
Check items:
(1) Check the connections for looseness or damage, especially check for exhaust leakage.
(2) Check the holding plate and the rubber for defective, crack or damage.
(3) If any part of the catalytic converter heat insulation cover is damaged or its depression extends to the
