In Buick Century automobiles, the EGR Valve assists in managing the circulation of expelling gases back into the chamber for consumption in the combustion process since pollutant rich blends will not suffice, it is healthier for the economy and environment. This system is to reduce NOx emission by forcing back some of the exhausted gas back into the cylinder to cool the combustion chamber and increase fuel efficiency. Through the years, various types of EGR valves had been used in Buick Century which range from simply a form of orifice jets up to having their own capability to respond to other conditions such as the coolant temperature and the manifold vacuum. Today's EGR systems can incorporate backpressure transducers that can adjust the flow according to the load that the engine is pulling. Even though EGR Valves are effective in fulfilling the necessary emissions, they tend to clog on Buick Century cars and thus should be cleaned periodically to work as they are expected.

Q: How to replace the EGR valve on Buick Century?
A:
The first step to replace an exhaust gas recirculation (EGR) valve includes a shutdown of ignition and the removal of the EGR Valve electrical connector. The EGR Valve needs the bolt at the pipe assembly removed to extract the pipe assembly gently. After disconnecting the EGR Valve electrical connector the next step is to remove the two retaining bolts that secure the EGR Valve assembly while also removing the gasket. The new gasket must be positioned before installing the EGR Valve onto the Intake Manifold while following the fastener notice in service precautions. Feed the bolts from the EGR Valve through the openings while tightening each one to 30 n.m (22 lb ft). After returning the pipe assembly to the EGR Valve it is essential to install the bolt followed by torqueing it to 30 n.m (22 lb ft). Connect the power cable of the EGR Valve as the last step.
