Q: How to service the alternator on those without a returnless fuel system on Mercury Cougar?
A: Service the alternator of vehicles without a returnless fuel system by first disconnecting the battery ground cable while ensuring both no smoking and no open flames exist due to the high risk of vapor ignition. Unplug both generator electrical connectors after removing the air cleaner outlet pipe together with the intake air resonator. The vehicle should be lowered after removing the accessory drive belt. Mark a point for generator connection and then detach the unit by first removing the lower bolt and secondly disconnecting both fuel supply and return lines. Placing extra care is essential because the removal space places limitations that could lead to damaging hoses or cables. To install the component follow the backward order of removal steps with continued attention to safety protocols for flammable materials.
Q: How to service and repair the alternator on Mercury Grand Marquis?
A: Service and repair operations for the alternator start with disconnecting the battery from the system. The first step requires removal of the nut and engine cover and a tight installation to 10 Nm (89 lb-in) torque should be applied before reassembly. First rotate the accessory drive belt tensioner in the clockwise direction before making preparations to set the accessory drive belt aside. After disconnecting the generator electrical connector you can secure the protective boot to one side and unscrew the generator B+ terminal nut with plans to tighten this junction to 12 Nm (106 lb-in) upon reinstallation. Start by taking out the battery cable harness pushpin mounted on the generator bracket before removing the 4 bolts holding the bracket in place. Reinstall these bolts to 10 Nm (89 lb-in). Remove the 2 bolts which secure the generator and attach them with a torque of 25 Nm (18 lb-ft) during reinstallation. Follow the steps to remove the cap and nut as well as the radial adapter. Then reinstall these components by tightening them to 10 Nm (89 lb-in). A complete procedure finish requires you to perform the reverse steps of the removal procedure.
Q: How to Ensure Proper Functioning of the Alternator in a Mercury Mariner?
A: Service procedures for the alternator should begin with placing your vehicle in neutral position on a hoist. The battery needs to be disconnected to avoid electrical problems. Turn the front end accessory drive belt tensioner to the counterclockwise direction while setting the accessory drive belt to the side. The service requires removal of the generator B+ protective cover and its terminal nut for replacement after tightening to 8 Nm (71 lb-in). To start the alternator service disconnect the generator electrical connector followed by moving the generator B+ cable to a safe position. The generator should be removed by uninstalling its lower air duct bolt while you should tighten this bolt to 4 Nm (35 lb-in) when reinstalling. Operating the locking tab will free the lower air duct from its connection to the generator before extraction. The generator shield installation starts with removing its bottom pin-type retainer followed by the generator shield nut for removal of the generator shield. Tighten all components to 20 Nm (15 lb-ft). The generator stud nut requires removal first while tightening it to 47 Nm (35 lb-ft) before removing the generator stud and tightening it to 24 Nm (18 lb-ft) for reinstallation. Researchers should first discard the generator along with its two bolts before torquing these bolts to 47 Nm (35 lb-ft) for installation. The final process becomes reverse-oriented by following the previous removal stages.
