What Causes the Engine to Make a Gurgling Sound Like Boiling Water?

The occurrence of this phenomenon in the engine is related to the coolant. A lack of coolant or the use of poor-quality coolant can lead to this issue. This situation is more likely to happen in summer and is commonly referred to as "boiling over," which can affect the vehicle's performance and lifespan. Below are some related explanations: 1. Boiling Point of Antifreeze: Antifreeze is produced by different manufacturers, and the freezing and boiling points vary by brand. Currently, the boiling point of antifreeze is generally above 105°C. If high-quality antifreeze is used, the "boiling over" phenomenon will not occur. 2. The quality of antifreeze can be measured by the following two main points: (1) Antifreeze Effect: The freezing point of water is 0°C, while ordinary antifreeze can typically reach -40°C. High-quality antifreeze should achieve around -60°C, which is an important indicator of antifreeze quality. (2) Boiling Point of Antifreeze: The boiling point of water is 100°C, while antifreeze should at least reach 108°C or higher. This means that the lower the freezing point and the higher the boiling point, the greater the temperature difference, and the better the quality of the antifreeze.

What to Do If You Forget to Bring Your Driver's License and Vehicle License While Driving?

If you forget to bring your driver's license and vehicle license while driving, you need to retrieve them promptly or provide valid proof. If you don't have the vehicle license with you, the vehicle will be temporarily impounded, and a compulsory measures certificate will be issued until you present the relevant proof (vehicle license). A penalty decision will then be made. The penalty for not carrying the vehicle license is between 20 and 200 yuan, with a deduction of 1 point. However, traffic police cannot issue an on-the-spot penalty decision; they can only impound the vehicle until you provide the vehicle license. Legal Basis: Article 95 of the Road Traffic Safety Law. If a motor vehicle driven on the road does not display a license plate, inspection qualification mark, insurance mark, or does not carry the vehicle license or driver's license, the traffic management department of the public security organ shall impound the vehicle, notify the party to provide the corresponding license, mark, or complete the required procedures, and may impose penalties according to Article 90 of this Law. If the party provides the corresponding license, mark, or completes the required procedures, the vehicle shall be returned promptly. Deliberately obscuring, damaging, or improperly installing the license plate will be penalized according to Article 90 of this Law. Daily Driving Precautions: Ensure the car doors are securely closed while driving. If you're unsure whether a door is closed properly, open it and close it firmly again. For vehicles equipped with a door-open warning function, pay attention to any alarm sounds or warning lights on the dashboard. Slow down when passing intersections between main roads and auxiliary roads. When approaching such intersections and unsure whether a vehicle is coming, reduce speed, proceed cautiously, and be prepared to brake in an emergency. When merging from an auxiliary road into a main road, the driver's view might be obstructed, making it difficult to assess traffic conditions from all directions. Failure to notice oncoming vehicles from the side during merging can easily lead to accidents.

Will you be notified on the same day if you fail the random inspection in Subject 3?

Subject 3 of the driving test is an audio-broadcasted examination. If any item is failed, the system will immediately announce it via audio. Below are the test items and precautions for Subject 3: 1. Starting the vehicle: First, adjust the seat and rearview mirror, check if the brakes, clutch, and accelerator are functioning properly, and ensure the surrounding environment is safe before starting. 2. Left/right turns and U-turns: Do not turn the steering wheel within 3 seconds of activating the turn signal, and ensure the vehicle speed matches the gear. 3. Passing bus stops, crosswalks, and school zones: Speed must not exceed 30 km/h, and check for pedestrians by looking left and right. 4. Gear shifting (upshifting and downshifting): Complete gear shifting within the specified time and distance. 5. Lane changing and overtaking: Do not turn the steering wheel within 3 seconds of activating the turn signal, and complete the maneuver within the specified time and distance. 6. Driving in a straight line: Speed must not be lower than 40 km/h, and steering wheel adjustments must not exceed 3 degrees. Complete straight-line driving within the specified distance. 7. Passing traffic lights: Stop and wait at red lights. If stopping midway, always use first gear when starting again. 8. Pulling over: Within the specified distance, choose an appropriate spot to pull over to the side.

What is the general weight requirement for vehicle fire extinguishers?

Generally, ordinary household vehicles are recommended to be equipped with a small fire extinguisher, which is lightweight and easy to carry, around 1kg, and relatively easy to fix in the car. However, from a safety usage perspective, it is more advisable to equip a fire extinguisher around 2kg. For medium-sized or smaller commercial vehicles, a larger capacity fire extinguisher should be equipped, typically a 4kg fire extinguisher; while for large buses or trucks, at least two 4kg or larger capacity fire extinguishers are required. Below are relevant introductions about fire extinguishers: 1. All commercial vehicles must be equipped: vehicles with fewer than 11 seats must have one ABC dry powder fire extinguisher of 4kg or more; vehicles with 11 seats or more must have two ABC dry powder fire extinguishers of 4kg or more. 2. Drivers must understand the performance and usage methods of fire extinguishers and be able to operate them proficiently in case of an emergency. 3. The equipped fire extinguishers must be within the validity period. Upon expiration, they must be re-equipped or the powder must be replaced to maintain effectiveness. 4. Vehicle fire extinguishers must be properly stored and placed in easily accessible locations in the vehicle. 5. The original fire extinguisher of the vehicle must not exceed its validity period. 6. Once a fire extinguisher is used, it must be re-equipped or the powder must be refilled. 7. Vehicle fire extinguishers must not be lent to others. 8. The safety department must conduct regular or irregular inspections of vehicle fire extinguishers to ensure each vehicle is equipped with effective fire extinguishers, guide drivers in storage and operation, and criticize, educate, suspend, rectify, or penalize those responsible for not equipping or having ineffective fire extinguishers.

What to Do When Car Tire Bolts Get Stripped?

You can pour some lubricating solvents like diesel onto the bolts. Applying appropriate foot force can increase the tightness of the nuts, but avoid reckless kicking as it may directly damage the nuts or bolts. You can use tools such as a hammer to strike the rear of the tire wrench, making the tire bolts and tool fit more tightly, which makes it easier to remove the tire bolts.

How to Avoid Crossing the Line in Subject Three?

For straight-line driving, first adjust the seat to find the most comfortable sitting position. Sitting too far forward or backward can negatively impact steering wheel control. If the steering wheel is not held steadily or not returned to the center, the car will naturally deviate.
