The easiest condition for replacing the alternator is to lift the vehicle on a hydraulic lift, remove the protective covers at the wheel arch, detach the auxiliary belt, remove the section of the intake duct of the intercooler, disassemble the auxiliary belt tensioner, the air conditioning compressor (without disconnecting the pipes), and then the alternator by disconnecting the cables connected to it (it is necessary to remove the fan to extract the alternator).

Then install the new alternator (you can also opt for a refurbished one) by proceeding in reverse.

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.
