What are the symptoms of a broken car suspension spring?

Symptoms of a broken car shock absorber spring: 1. Weak shock absorber rebound: The rebound force of the shock absorber is provided by the suspension spring absorbing road vibrations and impacts. Once the suspension spring is damaged, it will greatly affect the rebound force of the shock absorber. 2. Poor vibration filtering effect: As the suspension spring weakens, the overall vibration filtering effect of the vehicle will deteriorate. Additionally, when driving on extremely bumpy roads, there is a high risk of the shock absorber bottoming out. 3. Shock absorber noise: Bending damage to the suspension spring can also cause the spring end face to tilt. Once the spring end face becomes tilted or bent, it will rub against the spring base during operation, producing abnormal noises.

Does a car battery need to be replaced after 6 years?

There is no fixed replacement cycle for car batteries. If the battery's charging performance is poor, it is recommended to replace it. Below are some relevant details: Factors affecting battery lifespan: frequent modifications to the car's wiring, adding high-power headlights, installing high-power dash cams, one-touch window lifters, and other devices; poor driving habits, such as listening to music while driving or using the radio and music devices without starting the car; prolonged inactivity of the car, as leaving the car unused for extended periods can also damage the battery because the electronic devices remain connected to the battery, causing current drain over time. How to maintain a car battery: minimize modifications to the car's wiring and the installation of various electronic devices, as current overload can lead to excessive battery drain and ultimately shorten its lifespan; prevent the car battery from self-discharging by remembering to turn off all electronic devices before shutting off the engine; start the car regularly.

Can a 70-year-old driver still operate a vehicle?

70-year-old individuals are permitted to drive passenger cars. Regarding the allowable vehicle types for elderly drivers: 1. China's driver's license classifications are divided into several major categories: A, B, C, N, and P. 2. According to Rule 139, drivers aged 60 and above are no longer permitted to operate A, B, N, or P category vehicles, including A1, A2, A3, B1, B2, N, and P. This means that after turning 60, drivers cannot operate buses, large trucks, coaches, or medium-to-large trucks. 3. Upon reaching 60 years of age, a driver's permitted vehicle types will automatically be downgraded to a C1 license. Strictly speaking, a driver's license remains valid for life unless revoked due to legal violations. Elderly individuals can continue driving as long as they pass the required medical examinations.

Can 0w20 engine oil be used in summer?

Can 0w20 engine oil be used in summer? The meaning of the 0W20 oil grade is: 1. W stands for Winter, the abbreviation of winter. The smaller the number before W, the lower the low-temperature viscosity and the better the low-temperature fluidity, meaning it is suitable for lower minimum temperatures. 2. 20 refers to the viscosity at 100°C. The larger the number, the higher the viscosity and the stronger the high-temperature resistance. Extended content: 1. The composition of the oil grade includes two parts: classification and viscosity specification. The oil classification is represented by a combination of two letters. Those starting with "S" are for gasoline engines, those starting with "C" are for diesel engines, and those with both "S" and "C" are for both gasoline and diesel engines. 2. Generally, they are arranged in alphabetical order. The further back the letter, the higher the quality grade. The following number indicates the oil viscosity. The smaller the number, the better the fluidity in low-temperature environments and the lower the usable temperature, meaning it provides better protection for the engine during cold starts.

Is a tire pressure of around 2.9 bar dangerous on the highway?

Highway tire pressure around 2.9 bar is dangerous, as the normal tire pressure range is between 2.4-2.5 bar. The hazards of excessive tire pressure are as follows: Tire friction and adhesion will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear on the central tread pattern of the tire, shortening tire lifespan; increased body vibration indirectly affects the lifespan of other components; it causes excessive stretching deformation of the tire cords, reducing tire elasticity and increasing the load on the car while driving; puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and explosions, leading to blowouts. The method for resetting tire pressure is as follows: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep," then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data, and finally, the dashboard warning light will turn off, completing the tire pressure reset.

Does Mercedes-Benz Antifreeze Need to Be Diluted with Water?

Mercedes-Benz antifreeze needs to be diluted with water. The original high-concentration antifreeze has a very high freezing point, so it is necessary to add half the amount of water, meaning the mixing ratio of antifreeze to water should be 1:1. This way, the freezing point of the antifreeze can reach -37 degrees Celsius. Composition of Antifreeze: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can Different Antifreezes Be Mixed? The same brand of antifreeze must be used. Different brands of antifreeze may have varying production formulas. If mixed, multiple additives may undergo chemical reactions, rendering the additives ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -15 degrees Celsius, -25 degrees Celsius, -30 degrees Celsius, -40 degrees Celsius, etc. Generally, it is advisable to choose one that is at least 10 degrees Celsius lower than the lowest temperature in your region.
