• Q: How to remove the alternator on 2009 Toyota Sienna?

  A: Starting the alternator replacement demands first shutting out the V-bank cover sub-assembly and disconnecting the front wheel RH and the No. 1 engine under cover. The next task requires detachment of the front fender apron seal RH followed by engine coolant drain. The alternator removal procedure starts by taking out the No. 2 air cleaner inlet followed by the battery and then comes the front bumper assembly and front bumper energy absorber. Start by removing the No. 1 air cleaner inlet then disconnect the radiator reserve tank hose or pipe followed by disconnecting the No. 1 as well as No. 2 radiator hoses. You should remove the hood lock release lever protector along with the hood lock assembly and hood lock support sub-assembly. The cooling fan ECU connector gets disconnected followed by removal of the radiator upper support sub-assembly. After removing the No. 2 oil cooler outlet tube sub-assembly it is necessary to remove the headlight assembly RH, radiator side deflector RH, and headlight bracket RH. The service technician must remove the pressure feed tube assembly together with the radiator support cushion and the No. 1 radiator support and finally extract the radiator assembly that includes the fan shroud with the fan motor. Next, remove the V-ribbed belt. The removal process of the generator assembly begins by disconnecting the terminal cap followed by removing the nut and breaking the wire harness from terminal B then discharging both the generator connector and the compressor and magnetic clutch connector. Detach the two wire harness clamps while removing the two bolts in addition to the block-side bolt. The first step requires disconnecting the wire harness clamp then extracting the generator assembly while also removing the bolt and wire harness clamp stay until the bolt along with bracket separate.
