Does Windshield Washer Fluid Have an Expiration Date?

Windshield washer fluid does have an expiration date, which varies by brand, typically around 2 to 3 years. Windshield washer fluids are categorized into: regular windshield washer fluid, anti-freeze windshield washer fluid, and special anti-freeze windshield washer fluid. The method for adding windshield washer fluid is as follows: 1. Open the front hood; 2. Open the windshield washer fluid filler port; 3. Fill the windshield washer fluid up to the marked line. The performance and characteristics of windshield washer fluid include: 1. Cleaning performance: Composed of various surfactants and additives, surfactants have wetting, penetrating, and solubilizing functions; 2. Anti-freeze performance: Significantly lowers the freezing point of the liquid; 3. Anti-fog performance: Forms a single-molecule protective layer on the glass surface.

What does 99h mean on a tire?

99h indicates that the tire's load index is 775KG, and 'h' is the speed rating, representing a maximum speed of 210 kilometers per hour. The speed rating refers to the highest speed a tire can achieve under specified load and inflation pressure conditions. Most common vehicle models on the market typically use H and V speed ratings, while some high-performance vehicles use W and Y. Tire specifications are data that indicate the geometric parameters and physical performance of a tire. There are three methods for representing tire specifications: A. Metric (m); B. Mixed metric-imperial; C. Imperial. Imperial tire specifications are often represented by a set of numbers, where the first number indicates the tire section width and the second number indicates the rim diameter, both in inches. The most common markings on a tire are, first, the tire brand, followed by the tire specifications, and then the load index and speed rating. The speed rating is the maximum speed limit determined by the tire manufacturer after considering various factors and conducting tests during the design and production process. Exceeding this speed can lead to multiple safety hazards. Generally, all-terrain tires (AT) have lower speed ratings compared to highway tires to account for their performance on unpaved roads. Load index and inflation pressure. These typically indicate the maximum load and corresponding pressure, with the load measured in kilograms and the pressure (tire inflation) measured in kilopascals (kPa). A rubber strip or block on the side of the tire indicates the wear limit. When the tire wear approaches about 4mm from this limit, it's time to consider replacing the tire. The so-called "Three T's" refer to the three markings often found together on the sidewall of a tire: Treadwear (wear resistance index), Traction (traction performance), and Temperature (temperature index). These three indices are additional parameters beyond the conventional size, speed rating, and load index, allowing consumers to make more informed choices about tires, although they are not widely known. In addition to the model, tires also display the following common data: Tire cord material: Represented by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F.

What is the function of the exhaust system?

The exhaust system serves the following purposes: 1. Discharging the exhaust gases produced by the engine; 2. Reducing the pollution caused by the exhaust gases; 3. Minimizing noise. The components of the exhaust system include: 1. Exhaust manifold; 2. Exhaust pipe; 3. Catalytic converter; 4. Exhaust temperature sensor; 5. Muffler; 6. Tailpipe. The maintenance methods for the exhaust system are: 1. Regularly inspect the exhaust manifold for cracks and damage; 2. Check the exhaust pipe and catalytic converter for leaks and damage; 3. Examine the muffler for leaks and damage; 4. Inspect the gasket at the connection between the muffler and exhaust pipe for leaks, and check the rubber mounting gaskets of the exhaust pipe and muffler for damage; 5. Tighten the connecting bolts between the exhaust pipe and the engine exhaust manifold, as well as between the exhaust pipe and the muffler.

How Often Should Four-Wheel Balancing Be Done?

There is no set interval for four-wheel balancing. As long as the car does not pull to one side or vibrate, four-wheel balancing is not necessary. However, it can be checked during the 20,000-kilometer maintenance. Here is more information about four-wheel balancing: 1. Four-wheel balancing refers to the balance between the wheels when the vehicle is moving, commonly achieved by adding balancing weights. 2. Four-wheel balancing is performed on individual tires to ensure that the tire does not experience a shift in its center of gravity while rotating. 3. Four-wheel balancing simply involves removing the tire, placing it on a balancing machine, and checking the values displayed by the machine.

Where to Collect the Annual Inspection Exemption Sticker for Vehicles?

For vehicles exempt from annual inspection, the inspection exemption sticker can be obtained for free at the local vehicle management office or at inspection stations designated by the vehicle management office. According to regulations, motor vehicles that meet the 6-year exemption criteria are exempt from the on-site inspection (i.e., vehicle testing) process. However, they still need to apply for the annual inspection compliance sticker (the sticker placed on the front windshield, which has now been digitized nationwide) every two years. The exemption only removes the vehicle testing step; the inspection sticker must still be applied for biennially. The following documents are required: 1. "Application Form for Motor Vehicle Inspection Sticker" (applicable to vehicles exempt from inspection within 6 years, provided at the service window). 2. Original and photocopy of the vehicle owner's identity proof. 3. Original and photocopy of the vehicle's driving license. 4. Original copy of the compulsory traffic accident liability insurance certificate (retained by the traffic management department) (i.e., the original copy of the compulsory insurance). 5. Original and photocopy of the vehicle and vessel tax payment or tax exemption certificate.
