How to Remove and Service an EGR Valve on Mercury Grand Marquis?

Service of the EGR valve begins with unfastening the clamp while you remove the resonator and appearance cover. Cables attached to the intake manifold shield must be removed while vacuum lines need detachment for the next step. After removing the bolts securing the intake manifold shield it is time to detach the EGR valve from the exhaust manifold tube. Terminate the EGR valve retention with the bolts.

The EGR Valve in Mercury Grand Marquis vehicles regulates the circulation of fumes back to the chamber aiming at giving minimal air pollination. This exercise is known as Exhaust Gas Recirculation (EGR) where some of the published exhaust gas is again fed into the cylinder, thus minimizing peak temperatures and therefore NOx formation. The EGR technology over the years has evolved from simple orifice jets to the EGR valves controlled by some of the engine conditions; the current EGR systems utilize backpressure transducers for optimal EGR flow. Uninformed though, while EGR has been known to very helpful in reducing direct emissions, some of today's cars specifically the Chrysler Pentastar 3.6 does not use EGR, at least not in its engine design. Simple tasks like washing or even changing the clogged EGR valves' need to be performed from time to time for the smooth working and efficient results.
