How many kilometers should the spark plugs of Ford Mondeo be replaced?
3 Answers
The replacement cycle for spark plugs in the Ford Mondeo is 30,000 kilometers. The original engine uses NGK spark plugs, model LTR6AI-8. Spark plug replacement cycle: Under normal maintenance conditions, replace them when driving 40,000 to 60,000 kilometers. However, due to differences in brands and engines, it may vary. It is recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check if there are any leaves, dust, etc., on the outside and make sure to clean them thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it. Install the removed high-voltage distributor wires according to the ignition sequence, and snap the cover back on.
I've been driving a Ford Mondeo, and my experience with spark plug replacement tells me they should typically be changed every 40,000 to 60,000 kilometers. Delaying replacement can lead to difficulties in starting the car, insufficient power, and increased fuel consumption. My 2018 model had issues when I pushed it to 70,000 kilometers: the engine shook, and the mechanic said it was due to worn spark plug electrodes causing ignition failures. The specific interval depends on the engine model; for example, 2.0T engines wear spark plugs faster, so it's advisable to check them earlier. City driving with short trips accumulates carbon deposits more easily than highway driving. When replacing, choosing OEM parts is both cost-effective and reliable, costing around 300 to 500 yuan. Developing a habit of checking them every two maintenance sessions can help avoid the risk of breakdowns.
The spark plug is equivalent to the heart of engine ignition. For the Ford Mondeo, the common replacement interval is between 40,000 to 60,000 kilometers. Delaying replacement can weaken ignition performance, leading to incomplete combustion of the air-fuel mixture, affecting acceleration or increasing exhaust emissions. There are significant differences between models—for example, older 1.5L engines have shorter spark plug lifespans, while newer models with iridium-tipped plugs can last up to 80,000 kilometers. I make it a habit to have the mechanic check the electrode gap and carbon buildup whenever I change the oil, performing simple tests to avoid costly repairs. If you notice rough idling or sluggish acceleration, prioritize inspecting the spark plugs before the issue escalates to ignition coil damage.
