沃尔沃全系车型四万公里的保养项目包括：机油、机滤、空滤、空调滤、汽滤、火花塞、刹车油。清洗节气门。

　　The maintenance items for 40000 kilometers of all Volvo models include: engine oil, oil filter, air filter, air conditioning filter, steam filter, spark plug, and brake oil. Clean the throttle valve.

　　1、更换机油和机滤。

　　1. Replace the oil and oil filter.

　　常规保养就是经常说的小保（机油 机滤）一般是8000-10000公里做一次或半年做一次。建议：如果车的公里数10万以上或更高公里数，建议6000-8000公里做一次常规保养。

　　Regular maintenance is commonly referred to as minor maintenance (oil filter), which is usually done every 8000 to 10000 kilometers or every six months. Suggestion: If the mileage of the car is over 100000 kilometers or higher, it is recommended to perform routine maintenance between 6000 and 8000 kilometers.

　　2、更换空滤。

　　2. Replace the air filter.

　　空滤就是空气滤清器，它会过滤掉进入发动机内的灰尘，类似发动机的口罩。空滤材料为滤纸，为了增加空气的通过面，大多数滤芯加工时会做成有很多细小的褶皱，如果过滤不佳会增加油耗，更糟糕的是对涡轮增压器有一定损伤。建议每两万公里更换一个。

　　An air filter is an air filter that filters out dust that enters the engine, similar to an engine mask. The air filter material is filter paper. In order to increase the airflow, most filter elements are processed with many small wrinkles. If the filtration is not good, it will increase fuel consumption, and worse, it will cause certain damage to the turbocharger. Suggest replacing it every 20000 kilometers.

　　3、跟换空调格。

　　3. Replace the air conditioning unit.

　　空调格一般都是含活性炭材料，它可以吸收空气中的有害物质，主要过滤净化车内空气，尤其在夏天和冬天开空调车内味道重，建议深度清洗空调系统和更换空调格（两者缺一不可），建议每两万公里更换或季节交替时更换一个。

　　Air conditioning grids are generally made of activated carbon materials, which can absorb harmful substances in the air and mainly filter and purify the air inside the car. Especially in summer and winter, when air conditioning is turned on, the smell inside the car is strong. It is recommended to thoroughly clean the air conditioning system and replace the air conditioning grid (both are indispensable). It is recommended to replace it every 20000 kilometers or at seasonal intervals.

　　4、更换汽滤。

　　4. Replace the steam filter.

　　汽滤主要是起过滤汽油的作用，一般开车时有过油不顺感觉，很可能就是汽滤的油孔被油泥堵塞。沃尔沃厂家一般建议每2万公里更换一个。

　　The main function of the car filter is to filter gasoline. Generally, when driving, there is a feeling of poor oil flow, which is likely due to the oil hole of the car filter being blocked by sludge. Volvo manufacturers generally recommend replacing one every 20000 kilometers.

　　5、更换火花塞。

　　5. Replace the spark plug.

　　沃尔沃全系车型大多数是用的铂金火花塞。铂金火花塞的特点就是使用时间长，耐用性高，如果出现跳火或漏电现象要及时更换，火花塞建议每四万公里更换一次。

　　Most Volvo models across the range use platinum spark plugs. The characteristics of platinum spark plugs are long service life and high durability. If there is a spark or leakage phenomenon, it should be replaced in a timely manner. It is recommended to replace spark plugs every 40000 kilometers.

　　6、更换刹车油。

　　6. Replace the brake fluid.

　　刹车油对刹车系统至关重要，沃尔沃使用的是DOT4标号的刹车油。刹车油使用时间过长了会产生一定的含水量，刹车高温会使水分蒸发汽化，会让刹车油管形成气阻，导致刹车迟钝、滞后会使刹车距离变长甚至失灵等情况。建议沃友使用沃尔沃厂家指定的原厂原装刹车油。厂家指导要求刹车油一般两年或4万公里更换一次。

　　Brake fluid is crucial to the braking system, and Volvo uses DOT4 grade brake fluid. Excessive use of brake fluid can result in a certain amount of water content. High temperatures in the brakes can cause the water to evaporate and vaporize, leading to air resistance in the brake oil pipes. This can result in brake sluggishness, lag, longer braking distances, and even failure. I suggest that you use the original brake fluid specified by the Volvo manufacturer. The manufacturer's guidance requires brake fluid to be replaced every two years or 40000 kilometers.

　　7、清洗节气门。

　　7. Clean the throttle valve.

　　清洗节气门是很有必要的，因为没有被空滤过滤掉的灰尘都粘附着在节气门周边，遇到油气就会形成油泥。时间长了就会变成厚厚的积碳。建议节气门一般两万公里清洗一次。

　　It is necessary to clean the throttle valve because the dust that has not been filtered out by the air filter adheres to the periphery of the throttle valve, and when it encounters oil and gas, it will form sludge. Over time, it will turn into thick carbon deposits. It is recommended to clean the throttle valve every 20000 kilometers.
