Before proceeding with the alternator removal, disconnect the negative terminal of the battery. The alternator is located at the rear left of the engine bay (when facing the front) and can be accessed from above; disconnect the cables and the connector from the terminal block, loosen the belt, and unscrew the fixing bolts.

Remove the alternator from its location and fit the new one (it is recommended to opt for a refurbished product), checking the tension and amperage as well as the shape of the pulley. Proceed to secure it, reconnect the cables, and reposition the belt.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
