How many kilometers should antifreeze be replaced?

1 Answers

It is recommended to replace the coolant every 40,000 to 50,000 kilometers. Regular replacement of coolant is essential. Here is more information about coolant: 1. The full name of coolant is antifreeze coolant, but its main function is cooling rather than antifreezing. 2. Water-cooled engines rely on the continuous circulation of coolant within the engine for heat dissipation. When the engine is running, the water pump also operates, allowing the coolant to circulate within the engine and carry away excess heat. 3. There are two circulation paths for coolant within the engine: one is the major cycle, and the other is the minor cycle. When the engine has just started and the temperature is relatively low, the coolant will undergo the minor cycle, during which it does not pass through the radiator for heat dissipation. This helps the engine warm up quickly.

How many hours does an electric scooter generally need to charge?

An electric scooter generally needs to charge for 8 to 12 hours. After the scooter is fully charged, there will be a light reminder inside the vehicle, and it will automatically cut off the power once fully charged, which helps extend the scooter's lifespan. The charging time for an electric scooter should not exceed 12 hours, otherwise, the battery may wear out and its lifespan could be shortened. For the first charge, please note: 1. If the electric scooter has not been used and has not undergone charging and discharging, ensure the battery functions normally; 2. During the first charge, the charger heats up quickly, so do not place the charger on objects that can heat up or burn, nor on the scooter's seat, to prevent fire.

What are the new regulations for penalty points during the probationary period of a driver's license?

The new regulations for penalty points during the probationary period of a driver's license are: cancellation for full points during probation, extension of the probation period by one year if 6 or more but less than 12 points are accumulated during probation. Probationary Period: The first 12 months after a motor vehicle driver initially obtains a driver's license is the probationary period. Regulations may vary by region. During the probationary period, a probationary sign must be affixed or hung at the rear of the vehicle. The first 12 months after a motor vehicle driver initially applies for a driver's license or adds a permitted driving category is the probationary period. Cancellation and Downgrading: A full-point cancellation and downgrading system is implemented. If a motor vehicle driver accumulates 12 or more penalty points during the probationary period, the driving qualification for the probationary permitted driving category will be canceled. If the canceled driving qualification is not for the highest permitted driving category, the qualification for the highest permitted driving category will also be canceled.

How to Adjust Rearview Mirrors?

Adjusting the rearview mirrors starts with the left mirror. The driver should use the horizon as a reference, adjusting the vertical angle so that the mirror shows half sky and half ground. Then, adjust the horizontal angle so that the body of the car occupies about a quarter of the mirror's surface. Note that the adjustment should be based on the driver's seating position, not by leaning closer to observe the mirror. The right rearview mirror is the farthest from the driver's position, so we should reduce the space occupied by the sky, leaving more space for the side of the car body. Therefore, the right mirror should show one-quarter sky and one-quarter car body. A common mistake many car owners make when adjusting the central rearview mirror is using it to observe rear passengers or tilting it upwards to avoid obstruction. The correct adjustment is to ensure that the mirror provides a clear view through the rear window, with the ground and sky each occupying half of the view.

How to Revive a Dead Battery?

Methods to revive a dead battery: 1. Check if the battery is low on water. If it is, add distilled water, charge it at one-tenth of the rated charging current until fully charged, then discharge it at one-tenth of the rated capacity until fully discharged. Repeat this cycle three to four times to repair the battery. 2. Use a high-power charger with a high current to charge the battery. Stop charging when the battery gets hot and resume charging once the temperature drops. Continue this process for 2 to 3 days, repeating several times to activate the battery. 3. Connect the dead battery in parallel with a good battery and charge it using a charger. The operation involves finding a similar good battery based on your battery count, plugging in the charger for 20 minutes, and observing if the battery gets hot. If it does, unplug the charger and wait for 1 hour, then charge again for 20 minutes. Repeat this cycle three times, then fully charge the battery to restore normal function.

How to make up for failed ETC deduction?

Methods to make up for failed ETC deduction: The owner of the motor vehicle should go to the urban road, bridge, and tunnel toll collection service station to make up the payment within 15 days from the date of default. Alternatively, they can make the payment at designated banks, municipal post office collection points, or through the local ETC WeChat public account or Alipay service window. If the ETC shows a deduction failure when exiting the highway, under the guidance of the staff, you can switch to a manual toll exit and pay in cash. After successful payment, the ETC will not deduct again, nor will it affect the next highway passage. There are many reasons for ETC deduction failure, such as overdue credit card payments, expired credit cards, insufficient frozen funds in the savings card, frozen bank accounts, or canceled deduction agreements.
