If you’re a Mazda CX-5 owner and looking to maintain your vehicle for optimal performance, changing the spark plugs is an essential task that you should undertake at regular intervals. Spark plugs play a crucial role in the ignition process of your vehicle, and worn-out spark plugs can lead to decreased fuel efficiency, engine misfires, and rough idling. This guide will walk you through the step-by-step process of changing spark plugs on your 2016 Mazda CX-5, helping you keep your vehicle running smoothly and efficiently.
Tools and Materials You Will Need:
Before you start changing the spark plugs, make sure you have the following tools and materials handy:
- Socket wrench set
- Spark plug socket
- Torque wrench
- New spark plugs (make sure they are compatible with your Mazda CX-5)
- Spark plug gap tool
- Anti-seize lubricant
- Socket extensions
- Dielectric grease
Step-by-Step Guide to Changing Spark Plugs on 2016 Mazda CX-5:
Step 1: Prepare Your Vehicle
Park your Mazda CX-5 on a level surface and allow the engine to cool down. It’s always best to work on a cool engine to avoid burns and accidents. Once the engine has cooled, open the hood of your vehicle and locate the spark plug wires or ignition coils.
Step 2: Remove The Spark Plug Wires/ignition Coils
Depending on your specific model, you will either have spark plug wires or ignition coils. Carefully remove the spark plug wires or ignition coils from the top of each spark plug. Be gentle and avoid pulling on the wires themselves as it may cause damage.
Step 3: Remove The Old Spark Plugs
Use the spark plug socket and a socket wrench to carefully remove the old spark plugs from the engine. Turn the spark plugs counterclockwise to loosen and remove them from the engine. Inspect the old spark plugs for any signs of damage or wear.
Step 4: Inspect And Gap The New Spark Plugs
Before installing the new spark plugs, use a gapping tool to ensure that the gap between the center and ground electrodes is as per the manufacturer’s specifications. This gap is crucial for proper ignition and combustion within the engine. Once the new spark plugs are gapped correctly, apply a small amount of anti-seize lubricant to the threads of each spark plug.
Step 5: Install The New Spark Plugs
Carefully thread the new spark plugs into the engine by hand to avoid cross-threading. Once they are hand-tight, use a torque wrench to tighten the spark plugs to the manufacturer’s specified torque setting. Over-tightening can damage the spark plugs, while under-tightening can lead to poor contact and misfires.
Step 6: Reinstall The Spark Plug Wires/ignition Coils
If your vehicle uses spark plug wires, reattach them to the top of each spark plug, ensuring a snug fit. If you have ignition coils, carefully reattach them to each spark plug. Apply a small amount of dielectric grease to the inside of the boots of the spark plug wires or ignition coils to aid in conductivity and keep out moisture.
Step 7: Test Your Work
Once the new spark plugs are installed and all components are securely in place, start your Mazda CX-5 and listen for any unusual sounds. A smooth and steady idle indicates that the spark plugs are functioning correctly. If everything sounds good, close the hood of your vehicle and take your car for a test drive to ensure everything is in proper working order.
