In the case of 2007 and earlier, begin by unhooking the cable by the negative battery terminal, then proceed to disconnect the alternator drivebelt. Unscrew the electrical connections on the alternator, put the jackstands on the front of the automobile, and take out the lower bolts of the alternator. Unscrew the upper alternator bolt, and then wiggle the alternator to the rear, then hoist it in the air and lift it out of the engine compartment. Installation of the new alternator Before fitting the new alternator, fit the upper alternator bolt into its mounting boss hole. Installation is the opposite of uninstallation and once the battery is connected again, Powertrain Control Module has to learn anew its idle and fuel trim strategy. V6 models should follow these steps, which include loosening the driveaxle hub nut, disassembly of the right driveaxle, and the wiring harness clips, and then the alternator is removed. In the 2008 models, remove the negative battery terminal, lift the vehicle and take away the right lower splash shield and drivebelt. In four-cylinder models, delete air duct (lower), wiring harness guides, and alternator shield and delete alternator. In V6 models, unscrew the electrical connectors and unbolt the air conditioning compressor then take out the alternator. In 2009 to 2012 models, it is a similar process, but there are some steps to follow when handling four-cylinder engines and V6 engines. In 2013 and above models, lift the vehicle, loosen the negative battery cable and follow the required steps, 1.5L, 1.6L, 2.0L, and 2.5L engine, be sure to support the engine and extract the components needed before lifting the alternator out. Once the battery is reconnected, the Powertrain Control Module has to re-learn the idle and fuel trim strategy so that it can work at its best.
