The following maintenance should be performed at 50,000 kilometers for a car: 1. Replace engine oil and filter: Depending on the road conditions frequently driven on, normally change the oil every 5,000 kilometers; if there is a lot of dust, change the oil every 3,000 kilometers. 2. Check and replace brake pads: The lifespan of vehicle brake pads is about 4-5 years or 40,000 kilometers. The degree of wear varies depending on driving habits, driving environment, and speed. Generally, vehicles that frequently drive on highways experience minimal brake pad wear, while those often driven in the city with frequent traffic jams suffer more severe brake pad wear. 3. Check and replace spark plugs: They typically last 2-3 years or 20,000-30,000 kilometers. However, if the vehicle shows signs of insufficient power or acceleration shaking, it may indicate a problem with the spark plugs, which should be checked as soon as possible. 4. Clean the throttle body and fuel injectors: Over time, the throttle body and fuel injectors can accumulate dirt or carbon deposits and require regular cleaning. Generally, vehicles that have run over 50,000 kilometers need to be checked and cleaned, but the cleaning frequency should be determined based on the driving environment. 5. Clean the radiator: When a vehicle has been driven over 40,000-50,000 kilometers, the radiator often accumulates dirt and grime, affecting its cooling and cleaning functions for the engine. 6. Replace brake fluid: In addition to brake pads, brake fluid should also be replaced regularly. It can be replaced along with the brake pads or based on the mileage driven. 7. Pay attention to the tires, especially the spare tire: The typical lifespan of vehicle tires is also 4-5 years. Even if the mileage is low, tires often exposed to sunlight can age significantly. Therefore, if there are large cracks on the tire sidewalls or the tread pattern has reached the minimum limit, check whether they need to be replaced. Also, don’t forget to replace the spare tire. Although it is not used frequently, it is better to be prepared.
