Exhaust transaction catalytic converters burn off the excess gasses of the engine's emission, considerably reducing the engine's pollutant output. Lawns your vehicle on a solid, constant surface for user safety when working under the vehicle. Uplift the exhaust-side of the vehicle with a floor jack, and back the chassis on jack stands.2. Place the catalytic converter, which can be distinguished from remainder of the exhaust piping by its oval shape and larger width, also as its wired Oxygen sensor connections. Removing your dual exhaust's catalytic converter can be accomplished without removing remainder of the exhaust development.
Instructions
1. Grant your engine piece of date to frore off before removing the catalytic converter, as the comprehensive exhaust system Testament be highly baking from driving. New engine exhaust systems are required to constitute a catalytic converter. On dual exhaust setups, two catalytic converters are sometimes used, mounted to Everyone header down channel. Due to the further close temperatures, the catalytic converters propel under popular driving conditions, it is anticipated that the internal catalytic converter Testament wear away over generation, influential to emissions action malfunctions. For, a defective catalytic converter should be replaced these days.
On most dual exhaust systems, the catalytic converter Testament be located at about the middle of the vehicle. On dual exhausts featuring two catalytic converters, the converters may be located slightly further forward, connected directly to the exhaust headers.
3. Unplug the wired O2 sensor connection, located a few inches up the O2 sensor wire from the catalytic converter. Use an O2 sensor wrench to loosen and unthread the O2 sensor from the catalytic converter. If you don't have an O2 sensor wrench, a normal open-end wrench can be used instead. Be careful not to bang or damage the O2 sensor when removing it from the catalytic converter, as the sensor internals are very delicate.
4. Remove the two exhaust flange bolts at each end of the catalytic converter, securing it to remainder of the exhaust system. These tend to be very tight, so using a large-handled socket wrench to apply extra torque can be helpful. Once the flange bolts are removed, work the catalytic converter free of the exhaust system. It may be stuck into place by melted exhaust gaskets, but working it back in forth will free it from the flange connections. When reinstalling a catalytic converter or test pipe replacement, be sure to use new exhaust flange gaskets, as the worn stock gaskets will be prone to leaking if reinstalled.
