How to Service the EGR Valve on 2009 Mercury Mariner?

Service of the Exhaust Gas Recirculation (EGR) valve requires draining the cooling system first. The service of the EGR valve begins with removing the ACL outlet pipe followed by disconnecting its electrical connector. Remove the clamp after detaching the coolant hose from the EGR valve and use the tool to remove its two mounting bolts. Ensure you torque the new EGR valve to 20 Nm while installing it (177 lb-in). The correct method to clean sealing surfaces for the EGR valve is by using a plastic scraping tool to remove any EGR valve gasket residue because metal scrapers or wire brushes or abrasive tools should never be used due to their potential to cause leaks through gouges and scratches. The use of metal surface preparation becomes possible for cleaning when no gasket residue remains. The EGR valve gasket should not be reused and needs to be replaced by new ones while cleaning and inspecting the EGR gasket mating surfaces. Replace the original EGR valve gasket with a new one before performing the reverse order of the removal steps during installation. The service requires filling and bleaching the cooling system after completing these procedures.
