How often should the ignition coil of a Corolla be replaced?
2 Answers
Corolla ignition coils should be replaced approximately every 100,000 kilometers. They are devices that provide ignition energy. The Corolla is a 4-door, 5-seater compact sedan under FAW Toyota, with body dimensions of 4635mm in length, 1780mm in width, and 1455mm in height, a wheelbase of 2700mm, and a fuel tank capacity of 50 liters. The Corolla is equipped with a 1.2T turbocharged engine, delivering a maximum horsepower of 116 hp and a maximum power of 85 kW. It is paired with a 10-speed CVT continuously variable transmission. The front suspension features a MacPherson strut independent suspension, while the rear suspension utilizes an E-type multi-link independent suspension.
As a veteran driver who's owned a Corolla for ten years, I must say ignition coils aren't parts that require regular replacement. The decision to replace them should be based on symptoms - if your car shakes violently when starting, lacks power during acceleration, or the engine warning light comes on, those could indicate faulty ignition coils. Toyota vehicles are quite reliable, and ignition coils typically last between 80,000 to 120,000 miles or even longer before issues arise. I remember my first Corolla went 150,000 miles before needing its first replacement, with no major problems in between. I recommend having your mechanic inspect the ignition system during every maintenance visit to prevent minor issues from escalating. If you frequently experience engine stalling or shaking, don't hesitate to get it fixed immediately to avoid potential breakdowns. The average cost is around $300-$400 - no need to waste money replacing them prematurely.
