Cleaning the catalytic converter in a 2013 SV Altima can help maintain optimal engine performance and reduce emissions. Locate the catalytic converter, which is typically situated between the exhaust manifold and muffler.
Before starting any work, ensure the engine is cool to avoid burns. Wear gloves and safety glasses for protection. Disconnect the negative battery terminal to prevent electrical accidents. Use a wrench to remove the oxygen sensors and loosen the bolts holding the catalytic converter.
