  Q: Should you consult a dealer service department before replacing a catalytic converter due to a Federally-mandated extended warranty on Mitsubishi Galant?

  A:

  This is because there is, by law, an extended warranty covering the catalytic converter and other emission-related components. Therefore, before paying for your own converter replacement, see a dealer service department. The catalytic converter is a device in the exhaust system which reduces the pollutants in the exhaust gas stream. There are two types of catalytic converter. The oxidation catalyst reduces hydrocarbons and carbon monoxide. The reduction catalyst reduces oxides of nitrogen. All models addressed are equipped with three-way catalysts that can reduce all three pollutants. Because a catalytic converter testing device is expensive, and dealer service cost is high, if you believe it is malfunctioning, consult a dealer or a certified emission inspection facility. When servicing any underbody component, check that no leaks appear at the converter. Check for rust, dents and damage to the converter, especially at the welds and flange bolts. The catalytic converters rarely go bad, but they do become clogged; a vacuum gauge can help diagnose a blocked exhaust. Prior to loosening exhaust flange bolt or stud threads, spray them with a penetrant first as they tend to be rusty on the replacement. When removing the upstream catalyst from certain models, the upstream Oxygen Sensor should come out first. After separating the catalytic converter from the exhaust system, it is advisable to use new anti-seize coated fasteners for easier removal in future. The reinstallation of parts is done in reverse order of their removal, ensuring everything is properly tightened, and finally the engine is run to check for exhaust gases leakage.
