Alternator

Service and repair procedures for the Alternator start with disconnecting the negative Battery Cable followed by removing the washer solvent container. You must first disconnect the windshield wiper transmission link in front of the Wiper Motor before moving it out of operating range. Move the engine forward before you detach the Drive Belt. First disconnect the engine harness to generator output wire nut after removing the engine harness output wire from the generator and finally unplug the engine harness electrical connector . Remove the securing nut from the power steering lines that attach to the generator back stud while positioning the steering lines securely to the side. First remove the wire harness retainers on both shock towers before detaching the idler pulley bolt and pulley which are located on the engine's right front side. Begin by detaching the generator's lower bolt and stud and then its upper bolt, and finally remove the generator from its position. To install the generator first position it in the required spot then tighten the generator lower bolt and stud to a tight fit followed by generator upper bolt tightening to 50 n.m (37 lb ft). The idler pulley and bolt installation on the right front engine side should be followed by harness wire connection to shock tower retainers while positioning power steering lines and their retainer to the generator bracket stud. Install the power steering lines' retaining nut on the generator back. Then, connect the generator to the engine harness electrical connector and the ground. Finally, tighten the ground nut with a torque wrench set to 30 n.m (22 lb ft). Replace the Drive Belt, reposition the engine to its original placement and bolt the engine's mount strut into position. Finish the installation by connecting the windshield wiper transmission and washer solvent reservoir while reattaching the negative Battery Cable.

To replace the generator, first, disconnect the negative cable of the battery and disconnect the windshield wiper transmission link and place it aside. Perform a 360-degree turn of the engine, then remove the driveblelt. Detach the generator battery positive terminal and the regulator electrical connector, then remove the generator mounting nuts and bolts to get the generator out. For installing, locate the generator in its place and tighten the bolts to 50 n.m (37lb ft) and nuts to 30 n.m (22lb ft). Next , connect the drives belt generator battery also connect of the regulator electric connector , then re install the drive. Put the engine back to its normal place and tighten the engine mount strut bolts. Finally, repair the connection of the windshield wiper transmission and the negative Battery Cable.

Warning: disconnect the negative terminal first before proceeding with Alternator repair work. Before continuing you must disconnect the washer solvent container and windshield wiper transmission link before setting them aside. The engine needs to rotate forward before drivers remove the Drive Belt. Start by disconnecting the engine harness output wire and electrical connector from the generator while you remove the nut which secures the power steering lines to the generator. Disconnect the wire harness from its shock tower retainers while moving the power steering lines out of the way. Take out the generator by first removing its idler pulley bolt and pulley and then its lower bolt and stud before using the upper bolt to remove it. During installation place the generator into its correct position then use the lower bolt and stud to achieve initial tightness before installing the upper bolt and tightening all components to 50 n.m (37 lb ft). First reinstall the idler pulley with its bolt then connect the wire harness to shock tower retainers and guide the power steering lines back to the generator bracket before tightening the retaining nut. Use the generator's electrical connector and ground to retrieve power while tightening the ground nut to a torque of 30 n.m (22 lb ft). First replace the Drive Belt then put the engine back to its original position before tightening the engine mount strut bolts. Finally, reconnect the negative Battery Cable while also installing the washer solvent container followed by reconnecting the windshield wiper transmission.
