What maintenance items are required for a sedan at 50,000 kilometers?
1 Answers
Automotive maintenance at 50,000 kilometers should be divided into the following two scenarios: 1. If the vehicle has been properly maintained and underwent major maintenance at 30,000 kilometers, then at 50,000 kilometers, only an oil and oil filter change, four-wheel maintenance, brake inspection, chassis component check, and full vehicle fluid and lighting inspection are needed. 2. If major maintenance hasn't been performed, additional tasks such as throttle body cleaning, fuel injector cleaning, and replacement of the air filter, fuel filter, and cabin air filter are required. More details on automotive maintenance items are as follows: 1. Oil and oil filter replacement are mandatory for every maintenance session. Under the harsh conditions of high temperature and pressure inside the engine, the shelf life of oil is significantly reduced, and its performance degrades, eventually failing to protect the engine. The oil filter prevents impurities from mixing with the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both oil and oil filter should be replaced simultaneously. The air filter should be replaced every 10,000 to 15,000 kilometers. 2. If the vehicle's engine uses a timing belt, it should be inspected or replaced at 50,000 kilometers. However, if the engine uses a timing chain, replacement is not necessary. 3. Besides the items mentioned above, components like brake pads, tires, and the battery might also need replacement. If they haven't been replaced before, it's advisable to do so during the 50,000-kilometer maintenance. 4. Finally, maintenance also involves the inspection and servicing of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.
