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 process of replacing the exhaust gas recirculation (EGR) valve starts by unplugging the electrical connector before dismantling the egr pipe bolt and pulling the pipe assembly gently in reverse. The next step requires the EGR Valve bolts removal and the valve itself then comes out followed by the gasket. First, remove all dust from the EGR Valve Gasket mating surface before putting in place the new EGR Valve Gasket and attaching the EGR Valve. Secure the EGR Valve with bolts at 30 n.m (22 lb ft) torque and then restore the egr pipe to the EGR Valve by means of a bolt tightened to 25 n.m (18 lb ft). The EGR Valve electrical connector needs to be placed back into position at the end of installation.
