Preparing The Vehicle
Preparing your 2017 Jeep Renegade before changing spark plugs is essential. Proper preparation keeps you safe and makes the job easier. Follow these steps carefully to get started.
Ensure Engine Is Cool
Never work on a hot engine. Wait at least one hour after driving. A cool engine prevents burns and protects spark plug threads. Touch the engine to check if it feels cool enough to handle.
Disconnect The Battery
Disconnect the negative battery cable. This stops electrical current and avoids shocks. Use a wrench to loosen the battery terminal clamp. Keep the cable away from the battery to prevent accidental contact.
Accessing The Engine Bay
Open the hood by pulling the lever inside the Jeep. Secure the hood with the prop rod. Remove any plastic covers or engine components blocking spark plugs. Clear space carefully to avoid damage.
Removing Old Spark Plugs
Removing old spark plugs from your 2017 Jeep Renegade is the first step in maintaining its engine performance. This process needs care to avoid damage to the engine parts. Follow these simple steps to remove the spark plugs safely and efficiently.
Locate The Spark Plugs
Open the hood and find the engine cover. Remove it to see the ignition coils. The spark plugs sit below these coils. Your Jeep Renegade has four spark plugs, one for each cylinder. Identifying their exact position helps prevent mistakes.
Remove Ignition Coils
Disconnect the electrical connector from each ignition coil gently. Use a ratchet or socket wrench to remove the bolts holding the coils. Pull the coils straight up to avoid bending or breaking them. Set the coils aside carefully to keep them safe.
Extract Spark Plugs Safely
Use a spark plug socket and ratchet to loosen each spark plug. Turn counterclockwise until the plug is free. Pull the spark plug out slowly and straight to avoid damaging the threads. Check each spark plug for wear or damage before replacing.
Installing New Spark Plugs
Installing new spark plugs on your 2017 Jeep Renegade is a key step to keep the engine running smoothly. Proper installation helps improve fuel efficiency and engine performance. Follow these steps carefully to ensure the new spark plugs work as they should.
Check And Gap New Plugs
Check the spark plugs before installation. Each plug must have the correct gap for your engine. Use a spark plug gap tool to measure the space between the electrodes. Adjust the gap gently if needed. The right gap ensures proper spark and combustion.
Insert New Spark Plugs
Place the new spark plug into the spark plug socket. Carefully insert it into the cylinder head by hand. Avoid cross-threading by turning the plug slowly. Hand-tighten it until it is snug. This prevents damage to the threads and ensures a secure fit.
Tighten To Correct Torque
Use a torque wrench to tighten the spark plugs. Follow the manufacturer’s torque specification for the 2017 Jeep Renegade. Over-tightening can damage the plug or engine. Under-tightening can cause poor engine performance. Tighten the plug firmly but gently for best results.
Reassembling Components

Reinstall Ignition Coils
Place the ignition coils back onto the spark plugs. Make sure each coil fits snugly and sits flush. Secure the coils with their bolts. Tighten the bolts gently but firmly. Avoid over-tightening to prevent damage.
Reconnect Battery
Attach the negative battery cable to the battery terminal. Tighten the clamp to ensure a good connection. This step restores power to the engine. Double-check the connection to avoid electrical issues.
Double-check Connections
Inspect all connections and bolts. Confirm that ignition coils and wires are secure. Look for loose parts or missed steps. Proper checks help prevent engine misfires or starting problems. Take a moment to be sure everything is correct.
