Solution

1. Preparation

• Allow the engine to cool completely before starting work.

2. Remove Engine Cover

• Tools Required: Socket set

• Gently lift the engine cover off and set it aside.

3. Disconnect Ignition Coils

• Tools Required: Pliers (if applicable)
• Carefully disconnect the electrical connector from each ignition coil by pressing the release tab and pulling the connector straight off.
