Why Change Your Spark Plugs?

Spark plugs are crucial components in your Peugeot 208’s engine. They ignite the air-fuel mixture, allowing your car to run smoothly. Over time, spark plugs wear out, leading to various issues like:

• Reduced engine performance: Worn-out spark plugs can cause misfires, resulting in a loss of power and acceleration.
• Increased fuel consumption: Inefficient combustion due to faulty spark plugs leads to higher fuel consumption.
• Rough idling: A rough idle can be a symptom of worn-out spark plugs, causing the engine to vibrate excessively.
• Difficulty starting: Worn-out spark plugs can make it difficult to start your car, especially in cold weather.

To prevent these issues and ensure optimal engine performance, it’s essential to change your spark plugs regularly. According to Peugeot’s recommendations, spark plugs should be replaced every 30,000 miles or 3 years, whichever comes first. However, factors like driving conditions and fuel quality can affect the lifespan of your spark plugs.

Gathering the Necessary Tools and Materials

• New spark plugs: Refer to your Peugeot 208’s owner’s manual or consult a trusted mechanic to determine the correct spark plugs for your model.
• Socket wrench: A 16mm socket wrench is typically used for Peugeot 208 spark plugs.
• Torque wrench: A torque wrench is essential to tighten the spark plugs to the correct specifications.
• Spark plug gap gauge: This tool is used to check the gap between the electrodes of the spark plugs.
• Gloves: Protect your hands from dirt and grease.
• Safety glasses: Protect your eyes from potential debris.
• Rag: Clean up any spills or dirt.

Preparing Your Peugeot 208 for Spark Plug Replacement

1. Park your car on a level surface: Ensure the parking brake is engaged and the car is in “Park” (automatic transmission) or “1st gear” (manual transmission).
2. Disconnect the negative battery terminal: This is a crucial safety step to prevent electrical shocks. Locate the negative battery terminal (usually marked with a “-” sign) and use a wrench to loosen and remove the terminal.
3. Allow the engine to cool down: If the engine is hot, allow it to cool down completely before proceeding. This prevents burns and accidents.

4. Locate the spark plugs: The spark plugs are cylindrical components with a hexagonal head, usually protruding from the cylinder head.

Replacing the Spark Plugs

1. Remove the old spark plugs: Use the socket wrench to loosen and remove each spark plug, turning it counter-clockwise.
2. Inspect the old spark plugs: Examine the old spark plugs for signs of wear, damage, or fouling.
3. Clean the spark plug wells: Use a rag or compressed air to clean any dirt or debris from the spark plug wells.
4. Install the new spark plugs: Carefully thread the new spark plugs into the spark plug wells, turning them clockwise.
5. Tighten the new spark plugs: Use the torque wrench to tighten the spark plugs to the specified torque value. Refer to your Peugeot 208 owner’s manual for the correct torque specifications.
6. Reconnect the spark plug cover: Reinstall the spark plug cover, ensuring it is securely fastened.
7. Reconnect the negative battery terminal: Connect the negative battery terminal back to the battery.

Starting Your Engine and Checking for Issues

1. Start the engine: Turn the key to start the engine.
2. Listen for any unusual noises: The engine should run smoothly without any misfires or unusual noises.
3. Check for leaks: Inspect the spark plug wells for any signs of leaks.

If you encounter any issues, such as a rough idle or misfires, re-check your work and ensure the spark plugs are properly tightened. If the problem persists, consult a qualified mechanic.

Tips for Success

• Wear safety glasses and gloves: Protect your eyes and hands from potential hazards.
• Use a torque wrench: Tightening the spark plugs to the correct torque value is essential for proper function and longevity.
• Clean the spark plug wells: Ensure the spark plug wells are clean to prevent dirt or debris from interfering with the spark plugs.
• Dispose of old spark plugs properly: Do not throw old spark plugs in the trash. Recycle them or dispose of them according to local regulations.

Beyond the Basics: Additional Information

• Spark plug gap: The gap between the electrodes of the spark plug is crucial for proper ignition. If the gap is too wide or too narrow, it can affect the engine’s performance. Refer to your Peugeot 208’s owner’s manual for the recommended spark plug gap.
• Spark plug type: Different spark plugs are available, including copper, platinum, and iridium. Each type has its own advantages and disadvantages. Consult your owner’s manual or a trusted mechanic to determine the best type of spark plugs for your Peugeot 208.
• Spark plug fouling: Spark plugs can become fouled with carbon deposits or oil, reducing their efficiency. Regular maintenance and using the correct spark plug type can help prevent fouling.
