Chevrolet Express 3500 Replacement Catalytic Converter Information


The catalytic converter for the Chevrolet Express 3500 is a device that controls a vehicle's emissions by transforming the toxic results of combustion into substances that are less toxic via catalyzed chemical reactions. Most cars have three way catalytic converters. The central toxins that the converter deals with are carbon monoxide, nitrogen oxides and hydrocarbons that have not been burned. During the oxidation chemical reaction, carbon monoxide and hydrocarbons are turned into carbon dioxide and water vapor. The nitrogen oxides are altered through a reduction reaction into carbon dioxide, water and nitrogen. Minor damage to the catalytic converter may be fixed via welding or bonding the parts back together. However, damage to the honeycomb structure inside the converter will require a replacement. The most frequent sign of a damaged Chevy Express 3500 catalytic converter is a grating sound made during the exhaustion process or gas seeping from the shell of the converter.


They are available for the following Chevrolet Express 3500 years: 2013, 2012, 2011, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 13, 12, 11, 07, 06, 05, 04, 03, 02, 01, 00, 99, 98, 97, 96.
