Changing spark plugs on a 2016 Mazda CX-5 is a simple task. This guide will show you how to do it step-by-step.
If your Mazda CX-5 is not running smoothly, old spark plugs might be the cause. Spark plugs are vital for your engine’s performance. Over time, they wear out and need replacing. By changing them, you can improve your car’s efficiency and power.
This process may seem daunting, but it is straightforward with the right tools and instructions. In this guide, we’ll walk you through each step. You’ll learn how to safely and effectively change the spark plugs in your 2016 Mazda CX-5. Get ready to give your car a fresh start with new spark plugs.
Tools And Materials Needed
A socket wrench is a must-have. Socket extensions help reach deep spark plugs. Use a spark plug socket for easy removal and installation. A torque wrench ensures proper tightening. Pliers may come in handy. Use a ratchet for quick adjustments.
First, get new spark plugs. Check the manual for the right type. Use anti-seize lubricant on the threads. Get dielectric grease for better connections. Have a clean rag to wipe away dirt. A gapping tool is needed to set the spark plug gap. Safety gloves protect your hands. Make sure to have safety glasses too.
Preparation Steps
Changing spark plugs on a 2016 Mazda CX-5 involves a few key steps. Gather the right tools, like a socket wrench, spark plug socket, and gap gauge. Disconnect the battery, remove the engine cover, and replace each spark plug carefully.
Safety Precautions
Always work with a cool engine. Hot engines can cause burns. Disconnect the battery to prevent shocks. Wear gloves and safety glasses. Work in a well-lit area. Keep tools organized. Ensure no flammable materials are nearby. Double-check all connections.
Locating The Spark Plugs
Open the hood of your Mazda CX-5. Look for the engine cover. Remove it if needed. You’ll see the ignition coils. The spark plugs are underneath. There are four spark plugs. Each one is under an ignition coil. Use a socket wrench to remove the coils. Now you can see the spark plugs. Note their positions for reassembly.
Removing The Old Spark Plugs
First, make sure the car is off. Then, locate the battery. Disconnect the negative terminal using a wrench. This step is important for safety. It prevents any accidental electrical shocks.
Open the hood and find the engine cover. Remove the cover by unscrewing the bolts. Now, you can see the spark plug wires. Carefully remove these wires. They are connected to the spark plugs.
Use a spark plug socket to remove the plugs. Turn the socket counterclockwise. Once loose, pull out the old spark plugs. Be gentle to avoid damage. Now, you are ready to install new spark plugs.

Inspecting The Spark Plugs
Check the spark plugs for wear and tear. Clean or replace them if necessary. This helps keep your engine running smoothly.
Checking For Wear And Tear
Remove the spark plugs one by one. Look closely at the tips. Worn spark plugs have dull or rounded edges. Burnt spark plugs may show dark deposits. Check if the plugs are oily. Oily plugs mean oil is leaking into the engine. A cracked ceramic means the plug is damaged. Clean the plugs if they are not too dirty. Replace them if they are badly worn.
Identifying Common Issues
Misfires often come from bad spark plugs. The engine may shake or run poorly. Starting problems can also be a sign. If the car struggles to start, check the plugs. Poor fuel economy can mean the plugs are not working right. Engine knocking or pinging noises are other signs. Always check spark plugs first when these issues arise. Change them if needed.
Installing The New Spark Plugs
Changing spark plugs on a 2016 Mazda CX-5 involves removing the engine cover and accessing the spark plug area. Carefully unscrew the old plugs and replace them with new ones for better engine performance. Ensure all connections are secure before reattaching the engine cover.
Gapping The New Plugs
Use a gap tool to measure the gap on the new plugs. The gap should match the specifications in your manual. Adjust the gap by gently bending the ground electrode. This ensures the new plugs will work well.
Installing The New Plugs
Insert the new spark plugs into the engine. Hand-tighten each plug first to avoid cross-threading. Then, use a torque wrench to tighten them to the correct specification. Over-tightening can damage the threads. Attach the ignition coils back onto the plugs. Secure them with their bolts. Finally, reconnect the electrical connectors. This completes the installation.

Reassembling And Final Checks
Reassemble the engine components carefully. Ensure all connections are secure. Perform final checks to confirm the spark plugs are properly installed.
Reconnecting The Battery
Reconnect the battery terminal securely. Make sure there is no loose connection. Tighten the clamp well. This will ensure the power flows correctly. After reconnecting, close the hood gently.
Performing A Test Start
Turn the key in the ignition. Listen for any unusual sounds. The engine should start smoothly. If there is any problem, recheck the spark plug connections. Make sure everything is in place. A smooth start means the job is done right.
Maintenance Tips
Check your spark plugs every 30,000 miles. Look for any wear or damage. Bad plugs can cause engine problems. Clean around the spark plug area. This prevents dirt from entering the engine. Ensure all connections are tight.
Replace spark plugs every 60,000 miles. Old plugs can make your car run poorly. Your car may misfire. The engine may stall. You might notice poor fuel economy. Keep track of the mileage.
