• Q: How to replace the alternator on 2004 Toyota Matrix?

  A: The first step in alternator replacement requires disconnecting the battery negative terminal. Start by removing the cylinder head cover No.2 which was used for the 2ZZ-GE engine type and then separately uninstall the air switching valve assembly using the same engine type protocol. The engine under cover RH should be removed first followed by the generator V belt together with the fan. The process to remove the air pump outlet pipe from the 2ZZ-GE engine type involves disconnecting air hose No.5 and unfastening its two bolts. The procedure for removing the generator assembly begins with wire harness clamp removal followed by terminal cap No.2 removal after which the generator wire requires its nut to be untightened before disconnecting the generator connector. Start by disconnecting both the generator connector and the A/C connector before taking off the wire harness clamp. You will begin by taking off the bolt that secures the wire harness clamp bracket before detaching the generator bracket No.1 using two bolts for the 2ZZ-GE engine type and ending with the removal of two bolts to extract the generator. The generator assembly installation process requires positioning the components before securing them with two bolts and torquing bolt A to 25 N-m (250 kgf-cm, 18 ft-lbf), bolt B for the 1ZZ-FE engine type to 54 N-m (550 kgf-cm, 40 ft-lbf) and for the 2ZZ-GE engine type to 58 N-m (590 kgf-cm, 43 ft-lbf). The wire harness clamp bracket receives its bolt for the 2ZZ-GE engine type installation before torque reaches 5.4 N-m (55 kgf-cm, 48 in.-lbf). After connecting the A/C connector users should install the wire harness clamp before connecting the generator connector followed by mounting and torquing the generator wire nut to 9.8 N-m (100 kgf-cm, 7 ft-lbf). The installation of terminal cap No.2 and generator bracket No.1 should include two bolts for the 2ZZ-GE engine and require torquing them to 29 N-m (296 kgf-cm, 21 ft-lbf) before wire harness clamp installation. The air pump outlet pipe of the 2ZZ-GE engine type needs to be installed with torque set to 7.0 N-m (71 kgf-cm, 62 in.-lbf). After setting the fan and generator V belt in position you should install the engine under cover RH then the air switching valve assembly for the 2ZZ-GE engine type followed by the cylinder head cover No.2 for the 2ZZ-GE engine type. The installation ends with battery terminal connection followed by torquing the terminal to 54 N-m (55 kgf-cm, 48 in.-lbf).
