If the front shock absorber of a car is leaking oil, it needs to be replaced. Oil leakage from the shock absorber indicates damage, and its damping effect will gradually decrease. Over time, once the oil inside the shock absorber has completely leaked out, it will lose its damping function. Therefore, a leaking car shock absorber must be replaced, and the replacement should be done promptly. The working principle of a shock absorber: When relative motion occurs between the frame or body and the axle due to vibration, the piston inside the shock absorber moves up and down. The oil inside the shock absorber cavity repeatedly flows from one cavity to another through different pores. The friction between the pore walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vehicle's vibration energy into thermal energy of the oil, which is then absorbed and dissipated into the air by the shock absorber.

What is the method to reset the maintenance reminder for Kaiyi X3?

The method to reset the maintenance reminder for Kaiyi X3 is: After turning off the power, hold down the OK button on the steering wheel, then press the start button twice in succession (without starting the engine), and release the OK button after about 3-5 seconds, the indicator will disappear. More details are as follows: 1. As driving time increases, the wear and tear of internal components in the vehicle will gradually become more severe. To ensure the car operates normally, manufacturers have set up reminder indicators. After reaching a certain mileage, owners should promptly replace the components. After successful replacement, the maintenance reminder light needs to be reset. 2. The function of the light is to record the usage mileage of some important components, much like a timer in a sprint race, serving as a reminder for both the car owner and maintenance personnel. 3. Many car owners reset the corresponding maintenance reminder light after replacing car components, which is an official recommendation and something many owners are willing to do. If the owner replaces the relevant components but does not reset the light, it will not affect the vehicle's performance, but it may cause trouble for the next component replacement: it will be difficult to accurately know the usage time of the new components. 4. The 2017 Kaiyi X3 still uses a 1.6L-DVVT engine, with a maximum power of 93 kW and a maximum torque of 160 N·m. Its characteristic of high torque at low speeds makes it suitable for stop-and-go urban road conditions. Especially when overtaking or changing lanes, there's no need to deliberately increase the engine speed to quickly gain power, which not only makes driving more effortless but also helps reduce fuel consumption.

How often should the coolant in a Volkswagen car be replaced?

Generally, it should be replaced every two years or 40,000 kilometers. Coolant is a type of cooling liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Precautions for using coolant: 1. Try to use the same brand of coolant. Different brands of coolant use different metal corrosion inhibitors, so mixing different brands is not advisable. 2. Most coolants have a validity period of two years (some products may last longer). When adding coolant, ensure the product is within its validity period. When replacing, drain the old liquid completely, clean the cooling system thoroughly, and then add the new liquid. 3. Avoid diluting with water. Traditional inorganic coolants should not be diluted with water, as this can cause sedimentation, severely affecting the coolant's normal function. Organic coolants can be diluted with water, but excessive water should be avoided. 4. For vehicles using coolant, never top up directly with tap water. Instead, use distilled or deionized water. If these are unavailable, boiled and cooled water is better than tap water. If coolant is lost due to leakage, replenish with the same brand of coolant. Coolant should be used year-round; using tap water in summer is not scientific and may do more harm than good. 5. Some coolants may develop small flocculent precipitates after being stored for a year, which is usually caused by additive precipitation and does not require disposal. However, if large amounts of granular precipitates appear, it indicates the coolant has deteriorated and should no longer be used.

What is the tire size of the new Santana?

The new Santana has two tire size models: 185/60R15 and 175/70R14. In 185/60R15, the first number 185 represents the tire width of 185MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, and 15 represents the rim diameter of 15 inches. The middle letter "R" stands for radial tire. In 175/70R14, the first number 175 represents the tire width of 175MM, 70 indicates the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width, and 14 represents the rim diameter of 14 inches. The middle letter "R" stands for radial tire. In terms of wheel design, the new Santana adopts a 15-spoke intensive wheel style. It uses Hankook KINERGY series tires, which focus on economy, featuring fuel-saving and wear-resistant characteristics. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise. Do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts rotate instead of the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, and completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, and hand-tighten the nuts until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model, the tire is also marked with the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire. For practical use, such as "Standard rim 5.00F".
