An under-floor catalytic converter inlet is attached

to the exhaust manifold using fasteners and a gasket

for sealing (Fig. 7). A flex joint that is integral to the

converter allows movement between the engine and

the exhaust system. The converter outlet attaches to

the intermediate pipe.

The three-way catalytic converter simultaneously

converts three exhaust emissions into harmless

gases. Specifically, HC and CO emissions are converted

into water (H2O) and carbon dioxide (CO2).

Oxides of Nitrogen (NOx) are converted into Nitrogen

(N) and Oxygen. The three-way catalyst is most efficient

in converting HC, CO and NOx at the stoichiometric

air fuel ratio of 14.7:1.

plug wires from plugs or by any other means short

out cylinders. Failure of the catalytic converter can

occur due to temperature increases caused by

unburned fuel passing through the converter. This

deterioration of the catalyst core can result in excessively

high emission levels, noise complaints, and

exhaust restrictions.

Unleaded gasoline must be used to avoid ruining

the catalyst core. Do not allow engine to operate

above 1200 RPM in neutral for extended periods over

5 minutes. This condition may result in excessive

exhaust system/floor pan temperatures because of no

air movement under the vehicle.

The flex joint allows flexing as the engine moves,

preventing breakage that could occur from the backand-

forth motion of a transverse mounted engine.

(1) Loosen intermediate pipe-to catalytic converter

clamp.

(2) Remove muffler/intermediate pipe insolators as

necessary to slide muffle/intermediate pipe assembly

out of catalytic converter.

(3) 1.6L Engine - Disconnect upstream oxygen sensor

electrical connector.

(4) Disconnect downstream oxygen sensor electrical

connector (Fig. 8).

(5) Remove catalytic converter to exhaust manifold

attaching fasteners and remove converter from vehicle

(Fig. 9), (Fig. 10), (Fig. 11) or (Fig. 12).

(6) Remove and discard flange gasket.
