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

Service and repair of the EGR valve requires the removal of the air cleaner outlet tube then the disconnecting of the intake air bypass hose and positive crankcase ventilation hoses. The first step involves detaching the EGR tube from its position then completely removing the valve along with careful hose disconnect of the vacuum unit. While installing the valve, thoroughly cleanse the gasket surfaces on both the intake manifold and exhaust gas recirculation valve but prevent any waste material from getting inside each unit. Place the EGR valve correctly followed by its securement with bolts after installing the new exhaust gas recirculation valve gasket. Attach the EGR tube after reconnecting the vacuum hose while completing the process with the idle air control valve installation.

How to Service the EGR Valve on Mercury Mariner?

The exhaust gas recirculation (EGR) service requires placing a vehicle on a hoist within neutral gear. Start by emptying the cooling system while removing the outlet pipe for the air cleaner. The EGR valve requires electrical connector separation followed by disconnecting the upper radiator hose at the coolant outlet and the coolant hose from the EGR valve position. The two securing bolts on the EGR valve should be removed followed by disposal of the gasket material. The new EGR valve needs to be tightened to 20 Nm (15 lb-ft) torque during installation while completing the reverse installation process by cleaning the mating surfaces for the EGR gasket. The service completion requires you to fill and perform a bleed procedure on the cooling system.

Mercury EGR Valve reduces nitrogen oxides that are harmful by circulating combustion to exhaust. Mercury won its naming by providing mainstream drivers with smooth rides, toned cabins and sporty lines that outweighed the price, made comfort an entitlement, and allowed style to remain incisive enough to turn heads and yet not spend the same amount of money as a luxury car or cut corners on durability. Mercury continued adjusting the suspensions, dashboards and door seals to eliminate highway hum, placing control in their already hovering hands and reminding buyers that the badge included Roman-messenger roots that meant speed, communication, and an escape among the corporate clones. Mercury eventually no longer came out of showrooms in 2011 but its heritage continues to whisper through any remaining model as an easy steer, balanced on its feet, and muffling the noise of the road without necessarily causing a scream to the wallets. The present day EGR Valve injected waste gas into the intake stream, reduced flame temperature, reduced knock and allowed catalytic converters to open to lower loads that resulted in cleaner air and more consistent power during extended uphill pulls. A stepper motor operated EGR Valve opens or closes a pintle in milliseconds, opening wide during light cruise, clamping closed when you floor it, and changing in response to a variety of positions rather than being operated by fixed drill holes. Skip cleaning and the EGR Valve clogs up on carbon and chokes half open, spikes idle and would be taking away those hard earned emission gains. Routine maintenance ensures that the EGR Valve is clear and allows any Mercury to pass more stringent smog test without losing any torque during the daily commute.
