How Often Should Engine Ignition Coils Be Replaced?

[TaylorMarie]

Engine ignition coils should be replaced approximately every 100,000 kilometers. The ignition coil is located in the upper part of the spark plug within the engine compartment and is directly connected to the spark plug. Symptoms of aging engine ignition coils include: glue overflow, cracking, connection pipe issues, and erosion of the high-voltage nozzle. Daily precautions for engine ignition coils include: 1. Prevent the ignition coil from overheating or getting damp; 2. Turn off the ignition switch when the engine is not running; 3. Check, clean, and tighten the wiring connections to avoid short circuits or grounding. The function of the engine ignition coil is to convert the low-voltage electricity from the power source into high-voltage electricity, which is then transformed into a high-voltage spark by the spark plug to ignite the combustible gas mixture.
