How to service and repair the alternator on 2003 Toyota Corolla?

Start the alternator servicing procedure by disconnecting the engine under cover RH and the fan and generator V belt. The alternator requires disposal of the generator assembly by first discharging the wire clamp from the rectifier end frame wire clip then removing the rubber cap together with the nut before removing both the alternator wire and connector. The two alternator securing bolts should be removed as the last step. When installing the 12 mm head bolts tighten them to 25 Nm (250 kgf.cm, 18 ft.lbf) and the 14 mm head bolts require a torque of 54 Nm (550 kgf.cm, 39 ft.lbf).
