What are the major maintenance items at 100,000 kilometers?
3 Answers
Major maintenance items at 100,000 kilometers include: 1. Replacing engine oil and oil filter, which is a mandatory task for every maintenance service. Under the harsh conditions of high temperature and high pressure in the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates, eventually failing to protect the engine; 2. Replacing the cabin air filter to ensure fresh air when the car's air conditioning is in use; 3. Checking the brake fluid and brake pads, as brake fluid is affected by environmental humidity, leading to reduced braking efficiency over time; 4. Spark plugs should be replaced every 2 to 4 years. Even if they haven't completely failed, the decline in ignition performance can directly impact the car's power and fuel consumption.
I must say, after driving for so many years, the 100,000-kilometer mark is really a milestone. At this point, major maintenance items are crucial: changing the engine oil and filter is a must—it’s like giving the engine a bath, otherwise sludge buildup can damage the car; spark plugs also need to be replaced, or else misfiring will cause severe shaking; inspecting the timing belt is absolutely critical—if it snaps, the engine is done for, so don’t skimp on this cost; brake fluid and coolant should be refreshed too, as aging can lead to safety hazards; tires should be rotated or replaced, as excessive wear increases the risk of blowouts; air filters and cabin air filters should be swapped to ensure clean airflow and cabin air; a suspension system check can prevent strange noises, and changing the transmission fluid ensures smooth gear shifts. I recommend finding a reliable repair shop to handle it all at once, saving multiple trips. Don’t cut corners—if this step isn’t done right, future repairs will cost even more.
As a frequent long-distance driver, I pay special attention to the 100,000-kilometer maintenance. Changing the engine oil and oil filter are the basics to ensure smooth engine operation; a thorough inspection of the brake system is a must, including replacing the brake fluid and checking the brake pad thickness—safety comes first. If the spark plugs are worn out and not replaced, the car will struggle to accelerate; the timing belt and drive belt need careful inspection for cracks, as a break could cause major trouble. Replacing the coolant prevents overheating; don’t forget to check tire wear and conduct a battery health test—problems on the highway can be dangerous. I make a habit of listing these items and checking them one by one. If the budget allows, I even inspect the drivetrain. Neglecting maintenance for too long can lead to an early retirement for the car, so it’s better to spend some time on prevention. Remember, safety is no small matter.
