2004 Scion xA Parts Questions & Experts Answers

• Q: How to replace the alternator assembly on 2004 Scion xA?

  A: Start by removing the terminal cap followed by unfastening both the nut and generator wire until the generator connector disconnects alongside wire harness clamp removal. The repair process starts with bolts A and B loosening followed by relieving tension on the fan and generator V ribbed belt. After that, both components can be extracted from their positions. The process begins with bolt A and its nut which needs to be removed from the fan belt adjusting bar then proceeds to remove bolt B together with the generator. The first step for installation involves the temporary connection of the generator through bolt B while you insert the fan belt adjusting bar using bolt A and secure the nut with 11 Nm torque (112 kgf.cm and 8 ft.lbf). Install the fan and generator V-ribbed belt temporarily on their respective pulleys after positioning the adjusting bar between the engine mounting bracket and generator while pushing the bar toward the frontend to achieve proper V-ribbed belt tension. Avoid placing the adjustment bar between the oil control valve and generator to prevent damage. Start by torquing bolt A to 19 Nm (189 kgf.cm, 14 ft.lbf) followed by torquing bolt B to 54 Nm (551 kgf.cm, 40 ft.lbf). Begin by installing the clamped wire harness and connecting the generator connector. You should then attach the generator wire to the nut before tightening it to 9.8 Nm (100 kgf.cm, 7 ft.lbf). After that, install the terminal cap. Finally, inspect the drive belt.
