What Maintenance Should Be Done for a Car with 70,000 Kilometers?
2 Answers
For a car that has traveled 70,000 kilometers, the maintenance includes changing the engine oil, oil filter, cabin air filter, as well as inspecting the brake pads and brake discs. Below are the details of routine car maintenance items: 1. Engine Oil and Oil Filter Replacement: This primarily involves maintenance of the lubrication system, whose main function is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the engine oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car should undergo maintenance every 5,000 kilometers. 2. Filter Replacement: The air filter's function is to filter the air before it enters the cylinders, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is typically replaced after traveling 20,000-25,000 kilometers. 3. Spark Plug Replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, battery, throttle body, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, and their maintenance should be carried out based on usage conditions.
At 70,000 kilometers, there's quite a bit of maintenance to be done. Besides the mandatory oil and oil filter change, the air filter and cabin air filter should also be replaced, otherwise the car will have a heavy dust smell. The spark plugs are basically at the end of their lifespan, especially in turbocharged cars—not changing them can cause jerking. Transmission fluid is crucial; manual transmissions might hold out a bit longer, but automatic transmissions strongly recommend a change. Check the brake pad thickness and tire tread depth—last time at 70,000 km, my rear tires were worn down to the wear indicators. Rubber components in the chassis, like control arm bushings, may have aged and cracked; squeaking over speed bumps is a telltale sign. It's best to completely replace the coolant rather than just top it up. Finally, have the mechanic thoroughly inspect the electrical and fuel systems, as minor issues tend to start popping up at this mileage.
