1G – 2 ENGINE EXHAUST
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
EXHAUST SYSTEM
Notice: When you are inspecting or replacing exhaust
system components, make sure there is adequate clear-
ance from all points on the underbody to avoid possible
overheating of the floor pan and possible damage to the
passenger compartment insulation and trim materials.
Check the complete exhaust system and the nearby
body areas and tailgate for broken, damaged, missing or
mispositioned parts, open seams, holes, loose connec-
tions or other deterioration which could permit exhaust
fumes to seep into the luggage or passenger compart-
ment. Dust or water in the luggage may be an indication
of a problem in one of these areas. Any defects should
be corrected immediately.
MUFFLER
The muffler reduces the temperature, pressure, and
noise of the exhaust gas.
Aside from the exhaust manifold connection, the ex-
haust system uses a flange and seal joint design op-
posed to a slip joint coupling design with clamp. If holes,
open seams or any deterioration is discovered upon in-
spection of the front muffler and pipe assembly, thecomplete assembly should be replaced. The same pro-
cedure is applicable to the rear muffler assembly.
Heat shields in the front and rear muffler assembly posi-
tions, as well as for the catalytic converter and front ex-
haust pipe, protect the vehicle and the environment from
high temperatures the exhaust system develops.
CATALYTIC CONVERTER
Notice: 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.
Notice: The catalytic converter requires the use of un-
leaded fuel only, or damage to the catalyst will result.
The catalytic converter is an emission control device
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).
