Gently remove the plastic cover protecting the engine by unscrewing the four retaining screws. To avoid mixing up the cables, disconnect only the first spark plug.

Using a 10mm socket, unscrew the retaining nut of the first spark plug and pull the boot upwards. At the bottom of the well is the first spark plug.

Before proceeding with the removal, thoroughly clean the wells with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the appropriate spark plug socket, which has a rubber gripping device, gently insert it onto the spark plug head and unscrew it. Be careful not to drop foreign objects into the well.

Replace the spark plug with one of the same model, carefully inserting it into the well, always using the appropriate socket and turning it gently to ensure it screws in correctly. If you encounter resistance, remove it and try again.

Spark plugs should be tightened with a torque wrench; if you do not have one, screw them in without over-tightening. Proceed with the same operation for the other spark plugs.

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.
