The catalytic converter is a component of the vehicle's exhaust system. It contains a honeycomb structure made of ceramic or metal, which is coated with a catalyst material such as platinum, rhodium, and palladium. When exhaust gases pass through the catalytic converter, the high temperature and the catalyst material cause a chemical reaction that converts pollutants such as hydrocarbons, carbon monoxide, and nitrogen oxides into less harmful substances such as water, nitrogen, and carbon dioxide.
As the catalytic converter performs its function, it generates heat as a byproduct of the chemical reactions. This heat causes the catalytic converter to reach high temperatures, which can make it glow red when viewed from underneath the vehicle. However, it is important to note that a glowing catalytic converter does not necessarily indicate a problem. As long as the catalytic converter is functioning properly and within its recommended temperature range, it is safe for it to glow.
If you notice that your 2000 Chevy Cavalier's catalytic converter is glowing, it is important to have your vehicle inspected by a qualified mechanic to ensure that the catalytic converter is functioning correctly and to rule out any potential issues with the vehicle's exhaust system.
