Alternator

The replacement process starts with disconnecting the negative Battery Cable from the battery. Afterwards remove the accessory Drive Belt and the Radiator. Use a wrench to disconnect and remove the retaining bolt which secures the generator cooler outlet hose to the generator device. There are two operations to perform before you begin with the generator replacement. First disconnect the generator cooler inlet hose from both the generator and electrical connections which extend to the regulator, battery output and heated windshield (if present). Remove the generator bolts (1, 2) after initially loosening the lower bolt. Take the generator out of the vehicle. During generator assembly keep the unit on engine position and use the correct fasteners at proper locations according to specifications. Secure generator bolts 1, 2, 3 with 50 n.m of torque (37 lb ft). First tighten the battery output cable to 13 n.m. (115 lbs in) while reconnecting generator electrical connections. Then attach the generator cooler outlet hose to generator and its inlet hose to generator . Tighten the outlet hose bolt into place using 9 n.m. Pressure (80 lb in torque). Reinstall the Radiator then fit the accessory Drive Belt before reattaching the negative Battery Cable.

Begin Alternator service and repair by disconnecting the negative Battery Cable first followed by accessory Drive Belt removal along with cooling fans. Start by disconnecting the generator outlet hose from the generator via the retaining bolt. Next, disconnect the generator cooler inlet hose from the generator and the following electrical connections from the generator: the service and repair of the Alternator require disconnecting the negative Battery Cable from the battery then removing the accessory Drive Belt and cooling fans and generator cooler outlet hose and regulator and battery output and heated windshield electrical connections (if equipped). Prior to generator removal from the vehicle use a wrench to loosen the lower generator bolt followed by removal of generator bolts (1, 2). Follow the fastener notice in service precautions when placing the generator on the engine and tighten generator bolts (1, 2, 3) to 50 n.m (37 lb ft). Reconnect the electrical connections to the generator: the installation involves attaching the generator bolts (1, 2) and regulator along with the battery output (tighten to 13 N.m (115 lb in)) and heated windshield (if available). Position the generator inlet hose to the generator and outlet hose to the generator . Secure the outlet hose with retaining bolt tightened to 9 n.m (80 lb in). As the final step install the accessory Drive Belt and cooling fans before reconnecting the negative Battery Cable.
