Steps to replace the spark plugs on a Mazda Axela: 1. Disconnect the ignition coil harness plug and remove the ignition coil mounting bolts; inspect the spark plugs; 2. Select the appropriate tool to remove the spark plugs and take them out one by one. Cover the spark plug holes on the cylinder with a cleaning cloth to prevent objects from entering the cylinder interior; 3. Align the ignition coil with the spark plug and install it in place. Use a tool to screw in the bolts, clean the measuring tool, measure the spark plug gap, and determine if the spark plug is normal; 4. Check the appearance of the new spark plugs for any issues, install the spark plugs into the special sleeve, screw them into the spark plug holes using a digital torque wrench set to 25mm, tighten the spark plugs, and turn off the ignition switch; 5. Use the digital torque wrench to tighten to 8mm, start the vehicle, clear any faults, and tidy up the work area. The Mazda Axela is a car produced by Changan Mazda, featuring the new-generation "Skyactiv" technology and the new design theme "KODO," equipped with two Skyactiv gasoline engines.
Replacing the spark plugs on a Mazda Axela is actually quite simple. I've done it myself several times. First, prepare the necessary tools: a spark plug socket wrench, new spark plugs (recommended NGK or OEM models), gloves, and a 10mm wrench. Disconnect the negative terminal of the battery to prevent electric shock—this is crucial. Next, open the hood and remove the plastic cover or air filter assembly on top of the engine to access the spark plugs. Each cylinder has one spark plug, so remember to note their positions in order to avoid incorrect installation. Carefully unscrew the old spark plugs using the spark plug socket wrench, being cautious not to apply excessive force to avoid damaging the threads. After cleaning the installation holes, hand-tighten the new spark plugs and then gently turn them an additional half-turn with the wrench to secure them—do not overtighten. Once everything is reassembled, reconnect the battery and start the car to check if the engine runs smoothly. It's recommended to inspect the spark plugs every 30,000 kilometers, as worn electrodes on old spark plugs can negatively impact fuel efficiency and performance.
As a car owner, safety comes first. Pay attention to these when changing spark plugs: Make sure the engine is cooled down before starting, as operating on a hot engine can cause burns or damage parts. The first step is to disconnect the negative battery terminal to prevent electrical hazards. Wear protective gloves and goggles, as dust or oil around the spark plugs may fall into the engine. Buying matching spare spark plugs is inexpensive and saves money. Handle the protective cover gently when removing it to avoid pinching wires. After replacement, check for any looseness and start the vehicle to see if the idle is stable. If you encounter problems, don't force it—taking it to a professional is more reliable. Timely replacement can prevent ignition failure risks.
