Why Change Spark Plugs?

Spark plugs are crucial components in your car’s ignition system. They generate the spark that ignites the air-fuel mixture in your engine’s cylinders, enabling combustion and powering your vehicle. Over time, spark plugs wear out and can cause various issues:

• Reduced Engine Performance: Worn-out spark plugs can lead to a decrease in engine power and acceleration.
• Rough Idle: A misfire caused by faulty spark plugs can result in a rough idle, making your car vibrate and shake.
• Fuel Inefficiency: A malfunctioning spark plug can cause your engine to burn fuel inefficiently, leading to higher fuel consumption.
• Engine Misfire: A misfire occurs when the spark plug fails to ignite the air-fuel mixture, resulting in a noticeable engine hiccup or sputter.

Gather Your Tools and Materials

Before you start, make sure you have all the necessary tools and materials:

• New spark plugs: Consult your owner’s manual or a reliable online resource to determine the correct type and model of spark plugs for your 2016 Kia Soul.
• Socket wrench: A 16mm socket wrench is typically required for removing and installing spark plugs.
• Torque wrench: Essential for tightening the spark plugs to the correct specifications, preventing overtightening or loosening.
• Ratchet: Used to turn the socket wrench.
• Extension: May be needed to reach the spark plugs depending on the engine configuration.
• Spark plug gap tool: Used to adjust the gap between the spark plug electrodes, ensuring optimal performance.
• Gloves: Protect your hands from grease and dirt.
• Safety glasses: Protect your eyes from flying debris.

Preparing Your Kia Soul

1. Park your car on a level surface and engage the parking brake.
2. Disconnect the negative battery terminal. This prevents accidental electrical shocks while working on the engine.
3. Locate the spark plugs. The spark plugs are typically located on the top of the engine, near the cylinder head. Consult your owner’s manual for the exact location on your 2016 Kia Soul.
4. Remove any obstructions. Clear any wires, hoses, or other components that may be blocking access to the spark plugs.

Removing the Old Spark Plugs

1. Loosen the spark plug wires. Using a wrench or pliers, carefully loosen the spark plug wires from the spark plugs.
2. Remove the spark plugs. Using your socket wrench and ratchet, carefully loosen and remove the spark plugs. Be cautious not to drop the spark plug into the cylinder.
3. Inspect the old spark plugs. Observe the condition of the old spark plugs. Look for signs of wear, such as excessive electrode wear, carbon buildup, or cracks. This will help you assess the overall health of your ignition system.

Installing the New Spark Plugs

1. Clean the spark plug wells. Use a small brush or compressed air to clean any debris or dirt from the spark plug wells. This ensures a clean and secure fit for the new spark plugs.
2. Install the new spark plugs. Carefully install the new spark plugs into the spark plug wells. Ensure they are seated properly and hand-tighten them.
3. Use the torque wrench. Refer to your owner’s manual or a reliable online resource for the correct torque specification for your 2016 Kia Soul’s spark plugs. Tighten the spark plugs to the specified torque using your torque wrench. Overtightening can damage the spark plugs, while undertightening can cause them to loosen and misfire.
4. Reconnect the spark plug wires. Securely reconnect the spark plug wires to the new spark plugs, ensuring a proper connection.
5. Reconnect the negative battery terminal. Once all spark plugs are installed and connected, reconnect the negative battery terminal.

Starting Your Kia Soul

1. Start your engine. Start your car and listen for any unusual noises or rough idling.
2. Check for leaks. Inspect the spark plug area for any leaks or signs of oil or coolant.
3. Test drive your Kia Soul. Take your car for a short test drive to ensure everything is functioning properly.
