How to service the alternator on Mercury Mariner?

Begin servicing the alternator after positioning the vehicle on a hoist which is in neutral gear. First disconnect the battery after you remove the five bolts holding the RH lower splash shield with a torque of 8 Nm (71 lb-in). Move the accessory drive belt to the side through clockwise rotation of the front end accessory drive belt tensioner. Release the generator lower air duct by depressing its locking tab then remove it followed by removing the two battery harness locators and the heated oxygen sensor (HO2S) harness locator from the generator shield. Before generator B+ protective cover removal you should disconnect the generator B+ terminal nut which needs to be tightened to 12 Nm (9 lb-ft) before installation begins. The generator B+ cable needs to be moved aside before disconnecting the generator electrical connector. Reinstall the generator shield nuts with a torque of 20 Nm (15 lb-ft) after installation. First remove the pin-type retainer which is located at the bottom of the generator shield and then desynchronize the generator shield. Once the generator bolt is removed you should retighten it to 47 Nm (35 lb-ft) before proceeding with the removal of the 2 generator stud nuts that need to be tightened to 47 Nm (35 lb-ft) during reinstallation. The 2 generator studs should be tightened to 25 Nm (18 lb-ft) during reinstallation before the 3 screws securing the generator upper air duct are removed and re-tightened to 4 Nm (35 lb-in). The technician should first lower the vehicle on the hoist before taking out the generator and will reinstall the new generator using the same sequence for removal.

How to service the alternator on a returnless fuel system on Mercury Cougar?

The service of an alternator on vehicles with a returnless fuel system requires users to start by disconnecting the battery ground cable and avoiding smoking and open flames since these can ignite flammable vapors. Begin by disconnecting the generator electrical connectors while also taking out the air cleaner outlet pipe alongside the intake air resonator. Reach the accessory drive belt and then decrease the position of the vehicle. Remove the fuel supply line at the fuel injection supply manifold before detaching the generator by unstitching its lower bolt. Handle the removal process with care because restricted space could result in damage to any hoses or cables. During assembly you should reversely perform the uninstatllation procedure while maintaining safety protocols about flammable elements.
