Electrical ignition coils
OE NO.: 31359814 31358940

Applicable vehicle type: For Volvo

The ignition coil is the core component of a petrol engine's ignition system, functioning as a high-voltage transformer. Its primary role is to convert the vehicle's 12V low-voltage electricity into tens of thousands of volts of high-voltage electricity, supplying the spark plugs with the ignition energy required to ignite the fuel-air mixture within the cylinders. Its performance directly impacts engine starting capability, power output, and fuel economy.

Common Faults and Maintenance Points

• Common fault manifestations: If the ignition coil is aged or damaged, the vehicle may exhibit engine vibration, difficult starting, sluggish acceleration, increased fuel consumption, and in severe cases, cylinder misfiring with dashboard fault lights illuminating. Visible signs may include resin overflow, bulging, scorching, or rust.
• Maintenance and Replacement: Regular inspection is recommended every 60,000 to 100,000 kilometres. Condition can be assessed via diagnostic computer for misfire faults or by measuring voltage with a multimeter (normal value approximately 5 volts). Replacement requires matching the vehicle model and specification to avoid damaging the battery or engine. During routine use, prevent ignition coils from moisture exposure or overheating. Never leave the ignition switch on for extended periods when the engine is off, and never wash the coils with water.
