    Q:
    What is the purpose and operation of the EGR Vacuum Solenoid and EGR Valve on Chevrolet Caprice? Posted by Munashe M.
    A:
    The system reduces exhaust-emitted nitrogen oxides by recirculating a portion of the exhaust gas. The EGR valve, on the intake manifold, is central to this system. Two EGR valve types exist: negative and positive backpressure. It's inactive at idle and during deceleration, controlled by a thermal vacuum switch. EGR issues can cause rough idling and performance. To inspect, ensure the diaphragm plate moves freely and observe engine speed changes when manually depressed. Examine vacuum lines for blockages. Test the thermal vacuum switch with a gauge, replacing if faulty. For EGR valve replacement, disconnect vacuum hose, remove, and install a new valve with a gasket. For the switch, drain coolant, remove, and install a new one.
