Preparation
Changing spark plugs on a 2017 Jeep Renegade involves gathering the right tools and ensuring the engine is cool. Wear gloves to protect your hands and follow the manual for proper steps.
Safety Precautions
Always park the car on a flat surface. Turn off the engine and remove the keys. Let the engine cool down before starting. This prevents burns and injuries. Wear gloves and safety goggles. Keep a fire extinguisher nearby. Have a first aid kit just in case. Make sure you have the right tools ready. Double-check the tools before you begin. This ensures you don’t stop midway. Keep children and pets away. Safety first, always.
Locating The Spark Plugs
Open the hood of your Jeep Renegade. Find the engine cover and remove it. This will give you a clear view. Look for the spark plug wires. These wires are usually black or red. Follow these wires to find the spark plugs. The spark plugs are at the end of the wires. You may need a flashlight to see them clearly. The spark plugs are usually four in number. Check the manual if needed.

Removing The Old Spark Plugs
Ensure your safety first. Disconnect the car battery to avoid shocks. Locate the battery under the hood. Use a wrench to loosen the negative terminal. Remove the cable and secure it away from the battery.
Find the engine cover on top of the engine. It is usually held in place by screws or clips. Remove these using a screwdriver. Gently lift and remove the cover to access the spark plugs.
Locate the spark plugs in the engine. Use a spark plug socket and ratchet. Turn counterclockwise to loosen each spark plug. Carefully remove each spark plug from its hole. Handle with care to avoid damage.
Inspecting The Old Spark Plugs
Inspect the old spark plugs for wear and tear before replacing them. A 2017 Jeep Renegade needs new spark plugs if the old ones show signs of damage or erosion.
Signs Of Wear
Old spark plugs may show signs of wear. Check for any cracks on the ceramic part. Look for burn marks on the metal tip. Carbon buildup is another sign. The plug may appear black and sooty. If the spark plug is wet with oil or fuel, it is worn out. Erosion of the metal can also occur. A gap that is too wide or too narrow is a problem too. These are common signs of wear.
Determining Replacement Needs
Replacement is needed if the spark plug shows any of the wear signs. New spark plugs help the engine run smoothly. They improve fuel efficiency. They also reduce emissions. If the car hesitates to start, it may need new spark plugs. Poor engine performance is another clue. Regular checks can prevent bigger problems. Always use the recommended spark plugs for your Jeep Renegade.

Installing The New Spark Plugs
Gapping the spark plugs is important. Use a gap tool to check the gap. The gap should match the Jeep Renegade’s specs. Adjust the gap if needed. Make sure the gap is even. This helps the engine run smoothly. Always handle the plugs carefully. Avoid touching the electrodes.
Start by hand-threading the new plugs. This helps prevent cross-threading. Once hand-tight, use a torque wrench. Tighten to the proper torque spec. This prevents over-tightening. Over-tightening can damage the engine. Ensure each plug is snug. Do not use too much force. Reconnect the plug wires. Make sure each wire is secure. Double-check your work.
Reassembling The Engine
Put the engine cover back on the engine. Ensure it fits correctly. Use the screws you removed earlier. Tighten each screw firmly. Do not overtighten. Check for any loose parts. Everything should be secure. The engine cover protects important parts. It keeps dirt out of the engine. It also makes your engine look neat.
Locate the battery in your Jeep Renegade. Attach the positive cable first. This cable is usually red. Next, attach the negative cable. This one is usually black. Ensure both cables are tight. Loose connections can cause problems. Finally, check everything again. Make sure all connections are secure. Your Jeep is now ready to start. You have successfully changed the spark plugs.
Testing The Installation
Turn on the ignition. Listen for any strange sounds. The engine should start smoothly. If it does not, there might be a problem.
Check the dashboard for warning lights. Drive the car for a short distance. Pay attention to how the engine runs. It should be smooth and steady. If there are any issues, check the spark plugs again. Make sure they are installed correctly. Proper installation is key to engine performance.
Maintenance Tips
Change spark plugs every 30,000 miles. Check the owner’s manual for the exact interval. Old spark plugs can cause engine problems. Replace them on time. This keeps your Jeep running well. Keep a record of your last change. It helps to remember the next time.
Regularly check engine oil levels. Change the oil as per schedule. Inspect the air filter and clean or replace it if needed. Look at the coolant levels and top up if low. Listen for unusual engine sounds. Get them checked soon. Keep the engine clean. It helps it run better.
