Fit spark plug removal method: 1. Clean dust and oil stains around the ignition coils; 2. Unplug the ignition coil connector, use a socket wrench to loosen the ignition coil mounting bolts, then pull out the ignition coil; 3. After removing the ignition coil, use a socket to loosen the spark plug; 4. Once the target spark plug is loosened, remove it. The Fit is a hatchback model launched by GAC Honda, with dimensions of 4065mm in length, 1695mm in width, 1525mm in height, and a wheelbase of 2530mm. In terms of exterior design, the Fit adopts a new family-style front grille concept that integrates with the headlights, highlighting a sharp and sporty appearance.
Removing the spark plugs on a Fit isn't actually difficult—I often tinker with small car parts myself. First, park the car on level ground and turn off the engine, waiting for it to cool down—this step can't be skipped to avoid burns. Then, open the hood and locate the ignition coil position—for the Fit, it's usually on the cylinder head—and unplug the electrical connectors one by one. Prepare your tools: a 16mm spark plug socket wrench, and slowly turn counterclockwise to loosen, being gentle and avoiding excessive force. If a spark plug is stuck, spray some WD-40 rust penetrant and wait a few minutes. After removal, inspect the electrode wear on the old spark plug—it's a handy trick for assessing engine health. Before installing the new spark plug, apply a small amount of anti-seize lubricant and tighten it to 18-20 N·m with a torque wrench to ensure no air leaks. The whole process requires patience and attention to detail. For the Fit, replacing spark plugs every 60,000 km is recommended to save fuel and boost performance. Remember to clean up the workspace afterward to keep things tidy.
Let me share the key points of removal. The required tools include a spark plug socket and an extension bar. During operation, ensure the vehicle's battery negative terminal is disconnected to prevent short circuits. The steps involve unplugging the ignition coil connector from the cylinder head and unscrewing the spark plug with the socket. If you encounter difficulty in unscrewing, it may be due to carbon buildup; use a heat gun or spray to soften it first. It's crucial to use genuine Honda spark plugs that match the Fit engine to avoid affecting ignition efficiency. Don't forget any screws or parts during the process, and test the engine's smoothness after completion. Regular replacement can also reduce the chance of warning lights and prolong engine life, which is a good practice. Beginners are advised to refer to the repair manual to prevent mistakes.
