How To Install A Catalytic Converter Without Welding

• Select Year. Catalytic converters have been original equipment on most gasoline engine vehicles in the U.S. They have evolved since their inception, from 2-way converters to 3-way converters plus air, to the modern 3-way converter. Early 2-way converters, also called oxidation catalytic converters, were so called because they only converted HC and CO. In the late 1970s and early 1980s they were replaced on most vehicles by 3-way converters, which can also control NOx emissions.

A catalytic converter is one of the most important emissions components of the modern gasoline engine. It is part of the vehicle’s exhaust system, and is. Remove the O 2 (oxygen) sensor from the catalytic converter. Most modern catalytic converters are equipped with one or more oxygen sensors that monitor the efficiency of the car's exhaust system continuously. If your catalytic converter has an attached oxygen sensor, use an oxygen sensor socket and a ratchet wrench to disconnect it before proceeding.

I then went home and bought an $89 catalytic converter from Amazon.com (Magnaflow 99009HM Universal Catalytic Converter) that is supposed to fit my 96. Or should I call one of the backyard mechanics on Craigslist and have them cut the old one off and use exhaust clamps to put the new one on? How to Replace a Catalytic Converter. The catalytic converter, which is responsible for the cleanup of a vehicle exhaust, is a key component of a vehicle emission.

3-way converters are known as oxidation-reduction catalytic converters. In general a converter is composed of a cylindrical stainless steel enclosure housing a monolithic substrate which contains the catalyst. The most common catalyst materials are the precious metals platinum, palladium, and rhodium.

The substrate is constructed to expose as much exhaust gas as possible to the catalyst as it flows through the converter, for maximum conversion and efficiency. 2-way converters use platinum and palladium to oxidize CO and HC. Chip Life Read Write Software. 3-way converters also have rhodium to reduce NOx. Early 3-way converters had a separate substrate that oxidized CO and HC with help from additional oxygen supplied by an air pump. Modern 3-way converters use advanced chemistry, O2 monitoring and computerized fuel control to convert all 3 harmful gases without the need for additional oxygen. Various factors can cause converter failure.

Internal problems like plugging or reduced conversion efficiency are nearly always caused by engine problems like misfire, rich air/fuel mixture, coolant leaks, and oil burning. Misfires and excessive fuel can cause the converter to overheat and melt the substrate, while and can coat the surface of the substrate, preventing catalyst exposure to the exhaust.
