Part: Spark plugs

Video tutorial

As shown in the video, replacing the spark plugs in a Hyundai Genesis G70 is not difficult, but you need to be prepared with the right tools: you will need a T-handle wrench at least 4 inches long. Open the hood and remove the engine cover as well as the circular cap. Use a 10 mm Torx wrench to unscrew the four central bolts as shown in the video.

Disconnect the 4 clips and the connector to access the spark plugs located under the engine. With a torque wrench, reach and unscrew the four spark plugs.

Replace them with four new ones. When reinstalling, you should hear two clicks.

This noise means they are securely attached.

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.
