Alternator

Maintenance and repairs of alternators on 4.6L, 5.4L and 6.8L gasoline engines start with battery disconnection. The air filter element and inlet snorkel along with tray need removal through band clamp loosening on 5.4L and 6.8L engines. When servicing the air cleaner outlet pipe remove it from the 4.6L model. For models with air conditioning rotate the belt tensioner clockwise, otherwise follow the reverse direction before moving the accessory drive belt to a safe place. Start by disconnecting the generator electrical connectors before moving the generator B+ protective cover out of the way to unscrew and position the B+ terminal to the side. When reinstalling it should be tightened to 17 Nm (150 lb-in). Tear apart the generator bracket with four bolts that need to be tightened at 10 Nm (89 lb-in) when installing. The two secure bolts holding the generator must be removed prior to reinstallation where torquing them to 18 lb-ft (25 Nm) is necessary. To finalize the installation you should reverse the procedure that was used for removal.
