How often should the ignition coils on a Teana be replaced?

[XavierMarie]

The ignition coils on a Teana should be replaced approximately every 100,000 kilometers. The method for replacing the ignition coils is as follows: 1. Open the ignition coil cover on top of the engine; 2. Remove the screws securing the ignition coil; 3. Disconnect the ignition coil power plug and remove the old ignition coil to complete the replacement. The Teana is a mid-size sedan with the following body dimensions: length 4901mm, width 1850mm, height 1450mm, wheelbase 2825mm, fuel tank capacity 61.3 liters, and trunk capacity 586 liters. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum power of 115kW at 6000 rpm.

As a long-time owner of a Teana for nearly a decade, I don't think ignition coils need to be replaced at fixed intervals. My car has clocked 120,000 kilometers, and the coils are still in perfect condition with no issues. The key factors are driving habits and road conditions – frequent stop-and-go in congested urban areas or aggressive driving can cause higher coil temperatures and faster wear, possibly requiring inspection by 80,000 km. For smooth highway driving, you can safely stretch it to 100,000 km. The moment you notice symptoms like acceleration hesitation, engine misfires, or power loss, replace them immediately. Don’t underestimate it – a faulty coil can damage other components, leading to costlier repairs. During routine maintenance, have technicians check circuit voltage, and maintaining good battery health also helps extend their lifespan.

I've been driving a Teana as an Uber driver for several years, covering urban streets and alleys daily. There's no fixed replacement cycle for ignition coils. From experience, coil lifespan is greatly affected by driving conditions: in dusty and humid environments, they age faster; frequent stops and starts increase ignition cycles, putting more strain on the coils. On average, I recommend a thorough inspection around 80,000 km—continue using them if no issues are found. Symptoms matter more than time—replace when experiencing hard starts, engine light illumination, or sudden fuel consumption spikes. DIY replacement is simple: buy matching models online for just tens of dollars, but watch tutorial videos to ensure safety. Don't overlook regular spark plug changes—worn spark plugs add stress to coils, causing premature failure.

As a long-time Teana owner, I believe replacing ignition coils depends on usage. Generally, new cars are fine within 100,000 km, but if you notice sluggish acceleration or vibration, it's time to check. Ignition coils are consumables with an average lifespan of 60,000-80,000 km, but frequent cold starts in northern winters can accelerate wear. During maintenance, focus on checking spark plugs and wiring connections. Replacement isn't difficult - you can DIY with genuine parts or visit a small workshop, keeping costs low.
