Regular maintenance of your vehicle is essential to ensure its optimum performance and longevity. One of the key components that require periodic inspection and replacement is the spark plugs. Over time, spark plugs can wear out, leading to poor fuel efficiency, rough idling, and difficulty starting your engine. If you own a 2017 Jeep Renegade, knowing how to change the spark plugs can save you time and money.
Importance of Changing Spark Plugs
Spark plugs play a critical role in the ignition system of your vehicle. They deliver the spark that ignites the air-fuel mixture in the engine’s combustion chamber, creating the necessary power to propel your vehicle. As spark plugs wear out, they can cause misfires, decreased fuel efficiency, and engine performance issues. Therefore, replacing them at the manufacturer’s recommended intervals is crucial to maintain your Jeep Renegade’s performance.

Steps to Change Spark Plugs
Follow these step-by-step instructions to change the spark plugs on your 2017 Jeep Renegade:
- Prepare Your Vehicle: Park your Jeep Renegade on a level surface and allow the engine to cool down completely. This will prevent any burns from hot engine components.
- Locate the Spark Plugs: Open the hood of your vehicle and locate the spark plugs. They are usually attached to thick rubber wires and are positioned on the engine’s cylinder head.
- Remove the Old Spark Plugs: Carefully disconnect the wires from the spark plugs by gently twisting and pulling them. Use the ratchet wrench, extension, and spark plug socket to loosen and remove the old spark plugs from the engine.
- Inspect and Gap the New Spark Plugs: Before installing the new spark plugs, use a gapping tool to ensure that the spark plugs are set to the manufacturer’s specified gap. This is crucial for optimal engine performance.
- Apply Anti-Seize Compound: To prevent the new spark plugs from seizing in the engine block, apply a small amount of anti-seize compound to the threads of each spark plug.
- Install the New Spark Plugs: Carefully insert the new spark plugs into the engine cylinder head and tighten them by hand to avoid cross-threading. Use a torque wrench to achieve the manufacturer’s recommended tightness.
- Apply Dielectric Grease: Apply a thin coat of dielectric grease to the inside of the spark plug wire boots to prevent moisture and help with future removal.
- Reconnect the Spark Plug Wires: Carefully reconnect the spark plug wires to the new spark plugs by pushing them onto the plugs until you feel them snap into place.
- Test the New Spark Plugs: Start your Jeep Renegade to ensure that the new spark plugs are functioning properly. Listen for smooth idling and check for any warning lights on the dashboard.
