3. ENGINE COMPARTMENT LAYOUT
Do not work on the engine compartment while the engine, radiator, exhaust manifold, muffler
or catalytic converter is hot. Always turn the engine off and allow it to cool before starting the
maintenance.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine. -

1) Oxidation of DOC
The DOC oxidizes HC and CO of the exhaust gas in the two-way catalytic converter at 180℃ or

detects whether the DOC can burn (oxidize) the post-injected fuel or not, and sends the signal to

1. OVERVIEW OF EXHAUST SYSTEM
When you are inspecting or replacing exhaust system components, make sure there is
adequate clearance from all points on the underbody to avoid possible overheating of the
floor panel and possible damage to the passenger compartment insulation and trim
materials.
Check the complete exhaust system and the nearby body areas and trunk lid for broken,
damaged, missing or mispositioned parts, open seams, holes, loose connections, or other
deterioration which could permit exhaust fumes to seep into the trunk may be an indication of
a problem in one of these areas. Any defects should be corrected immediately. -
2. OVERVIEW OF MUFFLER
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint
design rather than a slip joint coupling design with clamp and U-bolts.
If hole, open seams, or any deterioration is discovered upon inspection of the front muffler and
pipe assembly, the complete assembly should be replace, the complete assembly should be
replaced.
The same procedure is applicable to the rear muffler assembly. Heat shields for the front and rear
muffler assembly and catalytic converter protect the vehicle and the environment from the high
temperatures that the exhaust system develops.
3. OVERVIEW OF CATALYTIC CONVERTER
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do not
contact the catalytic converter, as this could damage the catalytic converter. -
Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter. -
The catalytic converter are emission-control devices added to the exhaust system to
reduce pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and
palladium, which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from
the exhaust gas. The three-way catalyst has coatings which contain platinum and
rhodium, which additionally lower the levels of oxides of nitrogen (NOx). ·
