    Q:
    How to service the EGR valve on Buick LeSabre? Posted by Customer
    A:
    Service of the EGR valve begins by turning OFF engine ignition followed by disconnecting the exhaust gas recirculation (EGR) valve electrical connector. You must remove the two retaining nuts from the EGR valve before taking out the component. The removal of the gasket from the EGR valve adaptor allows cleaning the EGR valve adaptor surface free of contaminants and debris. You should install the EGR valve after putting a new gasket onto the EGR adapter and securing the EGR valve with two nuts that must be tightened to 30 N.m (22 lb ft). Reconnect the electrical connector that belongs to the EGR valve at the end of the repair process.
