Catalytic Converter: Description and Operation






DESCRIPTION




Figure 1 - View typical





WARNING:
The normal operating temperature of the exhaust system is very high. Therefore, never work around or attempt to service any part of the exhaust system until it is cooled. Special care should be taken when working near the catalytic converter. The temperature of the converter rises to a high level after a short period of engine operation time.

CAUTION:
Do not remove spark plug wires from plugs or by any other means short out cylinders. Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel passing through the converter.

There are two catalytic converters welded to the front exhaust pipe (1) near each bank inlet. One converter collects the exhaust from the right bank and a second one collects the exhaust from the left bank. The catalytic converters are not serviceable separate from the front exhaust pipe. If either catalytic converter requires service, the front pipe will need to be replaced Exhaust Pipe - Removal
