A catalytic converter is an emission control device in the exhaust system that reduces pollutants in the exhaust gas stream, with two types, an oxidation catalyst to lower the emissions of hydrocarbons and carbon monoxide, and a reduction catalyst to minimise the emission of oxides of nitrogen. All the models are fitted with two Three-Way Catalysts situated one below the other exhaust manifold flange with inlet pipe and mounting flange and an outlet pipe held by clamps. There is like a possibility of a particular product having a mechanical failure, therefore should it be suspected, it is wise to take it for diagnosis to a dealer or an authorized workshop. Leak check and structural damage or corrosion must be a routine check, and if any of these are seen, then the converter must be changed. To check for a restricted converter, it is always possible to use a vacuum gauge in order to measure the intake vacuum at idle and during a test throttle opening; if there will be a substantial drop in the middle of the readings, it is likely that a converter is restricted. For replacement, it should be secured on a repair rack and penetrating oil put on the bolts and nuts before removing the oxygen sensor and other necessary bolts and clamps. The catalytic converter can then be taken out and when reinstalling a new flange gasket should be used In addition, new bolts and nuts should be used every time with anti-seize compound for easy removal in future. When reconnected a converter, the support bracket has to be put in position using new fasteners that have to be tightened with force.
