Next, unbolt the generator bolts so as to remove the generator. For installation, fix the generator at its place with the generator bolt and tighten it with 50 n.m (37 lb ft). Put back the generator cable by attaching it and fastening it to the generator cable nut and tighten it to 9 n.m (80 lb in), and slide the boot onto the terminal stud. At that, hook up the generator electrical connector, regain the engine view shield should it have been detached, and replace the accessory Drive Belt. Finally, lift the vehicle again and reconnect negative Battery Cable and lower the vehicle.

Safety considerations before generator replacement begin with disconnecting the negative Battery Cable plus vehicle elevation. To begin the replacement of the generator start by removing the accessory Drive Belt followed by the engine sight shield (optional). Start by disconnecting the generator electrical connector and then complete the generator cable removal process by pulling down the boot before you remove the generator cable nut from the terminal stud. Finally remove the generator cable. The procedure requires removal of generator bolts before extracting the generator unit. Position the generator first then tighten each generator bolt to 50 n.m (37 lb ft). Align the generator cable then fasten its nut onto the terminal at 9 n.m (80 lb in) torque before putting the boot back on the terminal. Attach the generator's electrical connector and reinstall the engine sight shield when removed before reinstalling the accessory Drive Belt. After raising the vehicle once again connect the negative Battery Cable and lower the car to its original position.

In order to change the generator of the car with 4.2l engine, first unhook the battery negative cable, then remove the Drive Belt. Then, remove the air conditioning (A/C) line mounting bracket bolt at the engine lift hook, and then remove the right engine lift hook bolts to pull off the lift hook. Subsequently, remove the 3 generator mounting bolts to pull out the generator and disconnect the battery positive cable nut on the generator. For install use the positive cable of battery with the generator and secure it with the nut tightening to 9 n.m (80 lb in). Mount the generator and fasten using 3 bolts that need to be tightened up to 50 n.m ( 37 lb ft). Retighten the engine lift hook bolts and attach the hook to the engine with 2 bolts and tighten them to the same firmness of 50 n.m (37 lb ft). Then, install the a/c line bracket to the lift hook, fixing it with the bolt, with a tightening force of 10 n.m (89 lb in). Lastly, replace the Drive Belt, and reconnect the battery negative terminal.

Start the generator replacement process by disconnecting the negative Battery Cable while following thebattery disconnect caution. Start by separating the air cleaner assembly along with the Drive Belt followed by eliminating the regulator electrical link. Trim the generator by first removing the front mounting bolts and the rear mounting bolt along with the generator output (BAT) terminal nut. Hang the generator onto the vehicle first before installing its mounting bolts with limited torque. Fit the generator output (BAT) lead before installing the generator output (BAT) nut with loose physical tension. Use 50 n.m (37 lb ft) torque when tightening the generator mounting bolts together with 10 n.m (89 lb in) for the bat terminal nut. After plugging in the electrical connector of the regulator proceed with installing the Drive Belt before you reinstall the air cleaner then complete the installation by connecting the battery negative cable.

To replace the generator in vehicles with 4.8l, 5.3l, 6.0l, and 6.2l engines, take the necessary action starting by never left behind that to remove the negative Battery Cable. Remove the intake manifold sight shield and the accessary Drive Belt. Unplug the engine harness electrical connector from the generator, move the generator battery jumper cable boot. Disconnect the jumper cable nut and the terminal of the generator , then remove the generator bolts to remove the generator. To install, first install the generator and strictly follow the fastener notice.
