• Q: How to service and repair the alternator on 2005 Toyota Sequoia?

  A: The service process for alternator repair starts with taking off the engine under cover and the throttle body cover. The first step is to remove the intake air connector from the throttle body while also disconnecting the negative (-) battery terminal cable. Free the drive belt by rotating the belt tensioner clockwise while paying attention to its left-hand threaded pulley bolt so next remove the belt completely. To begin service and repair of the alternator start by removing the PS vane pump from the engine while proceeding to disconnect the generator by removing its generator connector and terminal cap and nut followed by disconnecting the generator wire and wire clamp from the cord clip. The generator must be taken out after removing both nuts and the single bolt. When installing the generator maintain its position with bolt and two nuts while torqueing the bolt at 39 N.m (400 kgf.cm, 29 ft.lbf) and the 10 mm nut at 39 N.m (400 kgf.cm, 29 ft.lbf) and the 8 mm nut at 15.5 N.m (158 kgf.cm, 11 ft.lbf). Secure the generator wire to the generator through the nut before tightening it to 9.8 N.m (100 kgf.cm, 87 in.lbf), and finally attach the terminal cap along with the wire clamp to the generator's cord clip. Reposition the PS vane pump together with the drive belt by rotating the belt tensioner clockwise based on the left-hand thread of the pulley bolt. After connecting the intake air connector to the throttle body the technician should do an on-truck inspection followed by throttle body cover and engine under cover reinstallation. After battery terminal reconnection the cable you must initiate the system since some setups need it after removing battery power.
