From Exhaust Gas Recirculation (EGR) Valves to O2 Sensors, your exhaust system has a critically important job to do to keep your car operating efficiently. Your vehicles exhaust system is engineered to withstand extreme conditions, including high exhaust temperatures, corrosive gasses, road salt (where applicable) and water. The vehicle’s exhaust system performs three important functions. It directs exhaust gases from the engine to the rear of the vehicle, it treats the exhaust gases to reduce emissions and it reduces noise produced by the engine’s combustion process.
Key components of the exhaust system include:
Malfunctions can be caused by environmental damage, or even problems with the ignition or fuel systems. Catalytic converters can be damaged if the check engine light is flashing and the vehicle continues to be driven. The exhaust system can be damaged from running over objects, and can deteriorate when exposed to corrosive road salt and moisture. Corrosion leads to exhaust leaks, noise, or objectionable odors and can cause illumination of the check engine light. Visit your local ACDelco service center for expert service and quality parts.
