The GM's 17110478 EGR Valve operates as a critical controller for exhaust gas recirculation (EGR) system operation in order to minimize NOx emissions from the combustion process. The GM part utilizes a strategic position close to the intake manifold to direct applied exhaust gas into the combustion cycle thus reaching peak temperature reduction and minimizing NOx formation. The EGR system requires systematic upkeep where professionals should inspect vacuum hoses together with both the EGR valve unit and the thermal vacuum switch which normally becomes worn out with time. A proper check of EGR valve diaphragm movement and responsiveness requires testing while the thermal vacuum switch needs vacuum gauge evaluation for proper functioning. A cleaning or replacement of the EGR valve can proceed once you disconnect the vacuum hose and unmount the hardware components. Five simple steps show correct reinstallation of the thermal vacuum switch including the application of thread sealer and following agreed-upon torque standards.
