What are the maintenance items for a car with 100,000 kilometers?

[RoseDella]

The major maintenance items for a car with 100,000 kilometers are as follows: 1. Use engine oil of the appropriate grade and replace the oil and filter regularly (every 5,000 kilometers). Frequently maintain the air filter and replace it regularly (every 20,000 kilometers). Regularly clean the fuel system and replace the fuel filter (every 30,000 kilometers). Regularly maintain the radiator mesh (every 30,000 kilometers). Replace the spark plugs regularly (every 40,000 kilometers or based on driving conditions). 2. The most important maintenance tasks are changing the engine oil and oil filter. The most frequent maintenance task is car washing. The parts that need to be checked most often are the tire surface and pressure, oil level, coolant level, and brake fluid level. Major maintenance requires replacing all vehicle fluids, the engine accessory belt, spark plugs, cleaning the throttle and fuel injectors, cleaning the three-way catalytic converter and intake manifold, and replacing the fuel filter.

My car just passed 100,000 kilometers, so I took it to the 4S dealership for a major service. The mechanic recommended changing the oil three-piece set, cleaning carbon deposits from the throttle body, and replacing the cabin air filter. The transmission fluid had to be completely replaced, as skipping this at this mileage could lead to issues. The brake fluid and coolant were also fully drained and refilled, and all chassis bolts were retightened. What surprised me most were the spark plugs—when removed, the electrodes were nearly worn flat. The tires were inspected and deemed good for another 5,000 kilometers, but I was advised to replace them at the next service. The entire maintenance took three hours, but the engine noise is noticeably quieter now, and gear shifts feel smoother. I recommend booking in advance to get a discount on labor costs.

100,000 km maintenance focuses on fluid replacement. Engine oil and oil filter must be changed; air filter and cabin air filter should be replaced based on dirt levels. Pay special attention to transmission fluid condition—automatic transmissions recommend a thorough flush using a machine. Test brake fluid moisture with a tester; replace if exceeding 3%. Check coolant freeze point and pH level—continue using if within specs. Inspect suspension components like control arm bushings and ball joint play, and check for looseness in tie rods. Spark plugs usually need replacement at this stage, especially for naturally aspirated engines. Test battery health—consider replacement if below 40%. Inspect belts for cracks and listen for chain noise. Finally, check tire wear patterns and brake pad thickness.

The 100,000-kilometer maintenance mainly includes several parts: Basic maintenance is a must, such as changing the engine oil and oil filter. Special attention should be paid to the transmission fluid, especially for automatic transmission models. Key safety items should be prioritized, for example, checking the brake fluid's water content—replace it immediately if it exceeds the standard. From an economic perspective, you can save on labor costs by purchasing and replacing the cabin air filter and engine air filter yourself online. Wear-and-tear parts like spark plugs are likely at the end of their lifespan and should be replaced directly. If the coolant hasn't been changed in three years, it's time to do so. Check the tires for uneven wear and consider getting a wheel alignment done at the same time. For other items, follow the maintenance advice, such as replacing the timing belt when it's due—don't delay.

As a frequent long-distance driver, I pay special attention to safety details during the 100,000-kilometer maintenance. In addition to the regular oil and three-filter change, I focus on checking the brake pad thickness - they should be replaced when worn down to 3mm. After a complete transmission fluid replacement, gear shifting feels noticeably smoother. The cooling system underwent pressure testing, revealing minor pipe leakage which was promptly addressed. Tire rotation extends service life, while wheel alignment prevents drifting. Battery voltage testing is essential to avoid roadside breakdowns. Lubricating seat tracks and sunroof rails ensures smoother operation. After maintenance, the chassis feels more solid during high-speed driving.

100,000 kilometers marks the mid-life stage of a car, making maintenance crucial. This time, I focused on replacing all fluids: engine oil and oil filter, transmission fluid using a flush machine for a thorough change, and brake fluid drained and renewed. I upgraded to iridium spark plugs for extended lifespan. A battery test revealed only 60% capacity remaining, so I replaced it outright. During the chassis inspection, cracked lower control arm bushings were found, leading to a full assembly replacement. Wheel balancing was done to reduce vibrations, and I took the opportunity to rotate the tires front to back. After cleaning the AC system, cooling became faster. It's advisable to bring the maintenance manual, as some items may be covered under warranty. Finally, I had the mechanic scan for trouble codes to eliminate potential issues.
