• Q: How to remove and install the alternator on 2007 Toyota Avalon?

  A: The alternator removal routine begins with disconnecting the negative battery cable followed by Vbank cover sub-assembly removal. Start by removing the generator V belt followed by the fan and then disconnect the wire harness clamp to unplug terminal B with a terminal cap and nut separation. Detach the generator connector from the generator assembly and separate the two bolts that secure the generator assembly and unfasten the nut from the cylinder block. The installation requires first removing the bolt before the wire harness clamp stay along with removing both the bolt and bracket. Begin installation by first mounting the generator assembly then fastening the bracket while tightening its bolt to 20 N.m (204 kgf.cm, 15 ft.lbf) and next securing the wire harness clamp stay with a torque of 8.4 N.m (86 kgf.cm, 74 in.lbf). The generator assembly installation requires bolting and torquing two fasteners to 43 N.m (438 kgf.cm, 32 ft.lbf). Additionally, the cylinder block nut requires torquing to 20 N.m (204 kgf.cm, 15 ft.lbf). The generator assembly receives the connector and the generator wire gets installed while the nut achieves a torque of 9.8 N.m (100 kgf.cm, 87 in.lbf). Terminal cap installation follows, then reconnection of the wire harness clamp. The procedure ends with reinstallation of the fan and generator V belt followed by the Vbank cover sub-assembly before reconnecting the negative battery terminal. The procedure of system initialization becomes necessary when disconnecting the battery terminal.
