How to Check the Production Date of a Car from the Glass?

There are three methods to check the production date of the car glass: 1. Numbers and dots format: The number represents the year, and the dots represent the month. Dots in front of the number indicate the first half of the year, and the month can be calculated by subtracting the number of dots from 7. Dots behind the number indicate the second half of the year, and the month can be calculated by subtracting the number of dots from 13. 2. Numbers with large and small dots format: The number represents the year, small dots represent the quarter, and large dots represent the corresponding month in the quarter. 3. First line with numbers and small dots, second line with large and small dots format: The number represents the year of glass production, small dots in the first line represent the month of that year, and the second line represents the corresponding days of the month, where large dots represent 10 days and small dots represent 1 day.

How to Choose a Low-Voltage Electrician Fire Extinguisher for Subject 4?

For Subject 4 low-voltage electrician fire extinguishers, carbon dioxide fire extinguishers and dry powder fire extinguishers are recommended. Below are the detailed introductions: 1. Carbon Dioxide Fire Extinguisher: Can be used for live fire extinguishing below 600V. When extinguishing a fire, first carry the extinguisher to the fire location, pull out the safety pin, hold the handle at the base of the horn with one hand, and firmly grip the pressure handle of the opening and closing valve with the other. The firefighter should stand on the upwind side of the fire source, 3 to 5 meters away. For carbon dioxide fire extinguishers without a discharge hose, tilt the horn 70° to 90°, and sweep from near to far at the base of the fire while standing sideways. Do not directly hold the outer wall of the horn or the metal connecting pipe with your hands to prevent frostbite. If the voltage exceeds 600V, remember to cut off the power supply before extinguishing. When used in a confined indoor space, the firefighter should leave quickly after extinguishing to avoid suffocation. 2. Dry Powder Fire Extinguisher: Can be used for live fire extinguishing below 50kV. The most common opening method is the pressure handle method: carry the extinguisher to an appropriate distance from the fire, invert it several times to loosen the dry powder inside. Then aim the nozzle at the most intense part of the fire, pull out the safety pin, press the handle, and the extinguishing agent will spray out. For extinguishers with a discharge hose or stored pressure, the hand should always press the handle without releasing; otherwise, the spray will be interrupted. 3. Foam Fire Extinguisher: The foam from this extinguisher contains a large amount of water, which is conductive and can cause electric shock when used, making it unsuitable for live fire extinguishing.

How to Remove Paint from Car Surface?

Here are the methods to remove paint: 1. Banana oil cleaning: Banana oil, also known as thinner. Banana oil can be used to dilute paint and has a good cleaning effect on paint spots. It is available in most paint stores, but be aware of its flammable, explosive, toxic, and volatile properties. 2. Gasoline cleaning: Gasoline, a well-known cleaning agent, has properties similar to banana oil and provides good cleaning results without the strong corrosive effects of banana oil. It can be applied by wiping with a damp towel. 3. Tar remover and adhesive remover cleaning: These are specialized cleaning agents with good cleaning effects and are relatively inexpensive. 4. Carburetor cleaner cleaning: This cleaner is much more irritating than tar remover but still has some cleaning effect. 5. Cleaning with car wash clay, also known as volcanic clay: After soaking in water for a while, it softens and has strong cleaning power without being corrosive, making it one of the best products available.

Can You Drive on Highways During the Probationary Period?

You can drive on highways during the probationary period, but certain conditions must be met. Below is a detailed introduction to the conditions for driving on highways during the probationary period: 1. Article 64, Paragraph 1 of "Order No. 123" stipulates: The first 12 months after a motor vehicle driver initially obtains a driver's license or adds a new permitted vehicle type is the probationary period. If the probationary period is extended, the 24 months starting from the "initial license issuance date" is considered the probationary period. 2. Article 65, Paragraph 2 of "Order No. 123" stipulates: When driving on highways during the probationary period, the driver must be accompanied by a licensed driver who has held a corresponding or higher-level driver's license for at least three years. The accompanying driver must sit in the front passenger seat and provide guidance to the probationary driver. Failure to comply with these requirements will result in a fine of 200 yuan.

Is it serious if the coolant exceeds the upper limit?

It is not a big problem if the coolant slightly exceeds the upper limit, but it may leave some stains. However, if it exceeds the upper limit significantly, it may cause excessive pressure. It is best to use a syringe to remove the excess coolant above the upper limit. When adding coolant, it only needs to be filled between the min and max marking lines. Below is some relevant information about coolant: 1. Coolant is an essential liquid for maintaining the normal operation of the engine. It continuously circulates in the engine water jacket to remove excess heat. Too little or too much coolant is not ideal. 2. When there is a shortage of coolant, never use tap water as a substitute. Distilled water can be used instead. Tap water contains minerals that can form scale at high temperatures, which may clog the engine's water passages or coolant pipes. 3. Replace the coolant promptly if its freezing point is insufficient. If the outdoor temperature is too low and the freezing point is inadequate, the coolant may freeze. When frozen, the volume of the coolant will expand, potentially damaging the engine.

How to Solve the High Water Temperature Issue in Beidou Star?

Beidou Star high water temperature solutions are as follows: 1. Check if components are functioning normally: Verify whether the thermostat can open normally and if it can fully open; then inspect whether the radiator surface has any dirt affecting heat dissipation. 2. Reasons for high water temperature: When there is excessive carbon buildup in the engine, under high load and high-speed conditions, heat cannot be fully dissipated, leading to increased water temperature; early ignition timing can also cause the engine temperature to rise during high-speed driving. 3. Inspect the cooling system: Also check if the water pump has any issues, as poor pump performance can lead to this phenomenon. Additionally, inspect and clean any scale buildup in the engine cooling system. It is recommended to visit an authorized 4S shop or repair facility for inspection.
