A driver should start the generator replacement on vehicles with 4.2l engines by disconnecting the battery negative cable followed by Drive Belt removal. Attack the engine lift hook by removing the bolt securing the air conditioning (A/C) line mounting bracket followed by the right engine lift hook bolts to extract the lift hook. Start by unbolting the generator from its mounting points using three bolts then disconnect the generator's battery positive cable's nut. Adhere the generator's battery positive cable using the provided nut by tightening it to 9 n.m (80 lb in). Fasten the generator using three bolts which require a torque of 50 n.m (37 lb ft). Screw in the engine lift hook with 2 bolts while tightening both fasteners to 50 n.m (37 lb ft). Fasten the a/c line bracket onto the lift hook then lock it with a bolt before tightening to 10 n.m (89 lb in). Complete the process by placing back the Drive Belt then reattach the battery negative cable.

Starting the generator replacement for a 4.2l engine requires first disconnecting the battery negative cable. Next, remove the Drive Belt. Begin by removing the bolt securing the air conditioning line mounting bracket from the engine lift hook and continue by uninstalling the right engine lift hook bolts to detach the lift hook. Pry off the three generator mounting bolts andextract the generator from the system. To disconnect the generator's power source use a wrench on the positive Battery Cable nut. Secure the battery positive cable to the generator through its designated nut while tightening to 9 nm (80 lb in). Secure the generator with three bolts which should reach a torque of 50 nm (37 lb ft). Reposition the engine lift hook while using two bolts to fasten it. These bolts require a torque of 50 nm (37 lb ft). Use the bolt to mount the a/c line bracket onto the lift hook until it reaches 10 nm (89 lb in) torque. Reinstall the Drive Belt and finish by attaching the battery negative cable.

Take out the air conditioning (A/C) line mounting bracket bolt at the engine lift hook, followed by the right engine lift hook bolts to remove the lift hook.
