How to service and repair the EGR valve on Mercury Cougar?

The EGR valve maintenance process should start by removing the air cleaner outlet tube followed by unconnecting the intake air bypass hose together with positive crankcase ventilation hoses. The exhaust gas recirculation valve requires tube removal before extraction of the valve which should be performed while disconnecting the vacuum hose. Service personnel must clean the gasket faces of the intake manifold before installation but must prevent both components from receiving debris entry. A new exhaust gas recirculation valve gasket should be installed while the EGR valve needs to be positioned correctly before securing it with bolts. Connect the vacuum hose before reattaching the EGR tube followed by installation of the idle air control valve.

In Mercury Cougar cars the EGR Valve helps in managing the circulation of the exhaust back into the combustion chamber hence controlling pollutants. This technique referred to as Exhaust Gas Recirculation (EGR) aids in reducing the nitrogen oxide emission through the recirculation of exhaust gas in order to reduce combustion temperature. With newest development, EGR technology however has emerged from simple orifice jets to complicated screws, which change corresponding to the conditions of the engine. Although EGR has proved helpful in the achievement of emissions targets, some of today's engines, for example, Chrysler Pentastar 3.6, does not use it. Routine servicing is important so that carbon accumulation is not allowed to block EGR valve to get ideal efficiency.
