Tools And Materials Needed
Before changing spark plugs on your 2016 Mazda CX-5, gather the right tools and materials. Having everything ready saves time and avoids frustration. This section lists the essential items you need for a smooth process.
Spark Plug Specifications
Use spark plugs that match Mazda’s recommendations. The 2016 CX-5 usually requires iridium-tipped plugs for better performance. The gap should be set to 0.044 inches or 1.1 millimeters. Check your owner’s manual for exact details.
Required Tools
Prepare these tools before starting:
- Spark plug socket (usually 5/8 inch)
- Socket wrench with extension
- Torque wrench for correct tightening
- Gap tool to measure spark plug gap
- Ratchet or breaker bar
- Compressed air or brush to clean the area
Safety Equipment
Protect yourself during the job. Use safety glasses to shield your eyes. Wear gloves to avoid cuts and burns. Ensure the engine is cool before starting work. Have a fire extinguisher nearby, just in case.
Preparing Your Vehicle
Preparing your 2016 Mazda CX-5 for a spark plug change is essential. Taking the right steps ensures safety and easier access. Follow these simple preparations before starting the job.
Park And Cool Down
Park your Mazda CX-5 on a flat surface. Turn off the engine and wait at least 30 minutes. Allow the engine to cool completely. Hot engine parts can cause burns. Cooling prevents damage to spark plug threads.
Disconnect The Battery
Open the hood and locate the battery. Use a wrench to remove the negative terminal first. Disconnecting the battery avoids electrical shorts. It protects you and the vehicle’s electronic parts.
Remove Engine Cover
Find the engine cover on top of the engine. Remove any bolts or clips holding it in place. Lift the cover carefully. This step gives clear access to spark plugs and ignition coils.
Locating The Spark Plugs
Locating the spark plugs on your 2016 Mazda CX-5 is the first step to replacing them. Knowing their exact position helps avoid confusion and saves time. The spark plugs sit inside the engine and connect to wires that carry electrical current. Accessing them may require removing some engine covers.
Identify Spark Plug Positions
The Mazda CX-5 has four spark plugs, one for each cylinder. They are arranged in a line on the top of the engine. Look for the engine cover and remove it gently if needed. The spark plugs sit under thick rubber boots or ignition coils. Each spark plug is located at the base of these boots.
Accessing Spark Plug Wires
Spark plug wires or ignition coils connect to the plugs. To access the plugs, you must first remove these wires or coils. Pull the boot firmly but carefully to avoid damage. Sometimes, a small clip holds the wire in place. Use a screwdriver to release the clip if necessary. Once removed, you see the top of the spark plug clearly.

Removing Old Spark Plugs
Removing old spark plugs is a key step to keep your 2016 Mazda CX-5 running well. This process helps maintain engine power and fuel efficiency. It also prevents misfires and rough idling. Careful removal ensures no damage to the engine parts. Follow these steps to remove the old spark plugs safely and correctly.
Detach Ignition Coils
First, open the hood and locate the ignition coils on the engine. Gently disconnect the electrical connectors from each coil. Use your hands or a small tool to press the clip and pull the connector out. Next, unscrew the bolts holding the ignition coils. Carefully lift each coil out to expose the spark plugs underneath. Set the coils aside in a safe place.
Use Spark Plug Socket
Attach a spark plug socket to a ratchet or extension bar. Place the socket over the spark plug and turn counterclockwise. Apply steady pressure to loosen the plug. Remove the spark plug slowly to avoid dropping debris inside the engine. Repeat this step for all spark plugs on your Mazda CX-5. Keep the old plugs for inspection or replacement.
Inspect Old Spark Plugs
Check the old spark plugs for wear and damage. Look for signs of carbon buildup, cracks, or oil deposits. These signs indicate engine problems or worn plugs. Compare the gap and condition to new spark plugs. This inspection helps decide if replacement is necessary. Proper evaluation keeps your engine healthy and efficient.
Installing New Spark Plugs
Installing new spark plugs on your 2016 Mazda CX-5 is a key step for good engine performance. Proper installation ensures smooth running and better fuel efficiency. Take your time and follow these steps carefully for the best results.
Gap Check And Adjustment
Check the gap on each new spark plug before installing. Use a gap tool to measure the space between the electrodes. The correct gap size is usually in your car’s manual. Adjust the gap gently if it is too wide or too narrow. Proper gap helps the spark plug fire correctly.
Hand Tighten First
Start screwing the spark plugs by hand into the cylinder head. This prevents cross-threading and damage to the threads. Turn them slowly and feel for resistance. If you meet strong resistance early, stop and check alignment. Hand tightening keeps the spark plugs in place safely.
Torque To Specifications
Use a torque wrench to tighten the spark plugs to the correct torque. The right torque value is in your Mazda CX-5 manual. Over-tightening can damage the spark plug or engine. Under-tightening may cause poor engine performance. Follow the exact torque for a secure fit.

Reassembling Components
After replacing the spark plugs on your 2016 Mazda CX-5, it is important to put everything back correctly. Reassembling the parts carefully ensures your engine runs smoothly. Take your time to reconnect each component the right way. This step helps avoid engine problems later.
Reconnect Ignition Coils
Start by placing the ignition coils back on the spark plugs. Push each coil down firmly until it clicks into place. Reattach the coil connectors securely. Loose connections can cause misfires or engine trouble. Double-check each coil to make sure it is tight and properly seated.
Replace Engine Cover
Next, put the engine cover back on. Align it with the mounting points carefully. Press it down evenly so it fits snugly. Secure the cover with the bolts or clips you removed earlier. A properly installed cover protects the engine and keeps dirt out.
Reconnect Battery
Finally, reconnect the battery cable. Attach the negative terminal first. Tighten the clamp firmly to ensure a good connection. This step restores power to your vehicle’s systems. Check that all tools and parts are out of the engine bay before closing the hood.
Testing After Replacement
Testing after replacing the spark plugs is important. It ensures your 2016 Mazda CX-5 runs well. This step checks if the new spark plugs work properly. It helps find any issues early. Follow these simple steps to test your vehicle after the change.
Start The Engine
Turn the key to start your Mazda CX-5. Listen to the engine sound carefully. The engine should start quickly without hesitation. A smooth start means the spark plugs are working well. If the engine struggles, there might be a problem.
Check For Smooth Performance
Let the engine run for a few minutes. Notice any rough idling or shaking. The engine should run smoothly and quietly. Watch for any unusual sounds or vibrations. Smooth performance shows the spark plugs fire correctly.
Address Any Issues
If the engine runs rough or stalls, stop the test. Double-check the spark plug connections and gaps. Make sure the spark plugs are the correct type. Clean or replace any faulty parts. Fixing problems now prevents bigger issues later.
