When a car's water pump fails, it mainly exhibits the following symptoms: 1. The engine coolant temperature rises and does not decrease; 2. Water leakage occurs near the water pump area of the engine; 3. Unusual noises come from the water pump area after starting the engine. Here is some relevant information about water pumps: 1. Automotive engines widely use centrifugal water pumps. Their basic structure consists of components such as the water pump housing, connecting flange or pulley, water pump shaft and bearings or integrated shaft bearings, water pump impeller, and seal assembly, making them a major component of the vehicle. 2. They are generally driven by the engine's crankshaft via a V-belt. The drive belt wraps around the crankshaft pulley and the water pump pulley, causing the water pump shaft to rotate as the crankshaft turns. The water pump shaft then drives the impeller to rotate, thereby converting mechanical energy into hydraulic energy.

What is the box on top of a sedan?

The box on top of a car is a roof cargo box. Here are specific details about roof cargo boxes: 1. Purpose of roof cargo boxes: Not all items are suitable for storage inside the car, such as skis, outdoor equipment, and protective gear. If these items must be carried, they may occupy significant space, compromise interior cleanliness, or even pose safety hazards. A roof cargo box provides an alternative storage solution. 2. Advantages of roof cargo boxes: During trips, the car interior often accommodates multiple passengers, leaving insufficient space for everyone's equipment. Roof cargo boxes are popular due to their streamlined design, large storage capacity, low wind resistance, and features like theft prevention, wind protection, and dust resistance.

Do more people fail Subject 2 or Subject 3 in the driving test?

Subject 3. Here are the relevant details: Reasons: Compared to Subject 2, in the minds of students, Subject 3 not only involves computer system scoring but also requires an examiner in the car to ensure the safety of the candidate. Many candidates become extremely nervous upon seeing the examiner, leading to oversight of many details during the test, ultimately resulting in failure. Therefore, Subject 3 is considered more difficult. Subject 2: Subject 2 mainly consists of five small tasks, with the most common failures occurring in hill parking and starting, parallel parking, and reversing into a parking space. The reasons for failure include not pressing the clutch properly, poor speed control, and late steering wheel adjustments. Subject 3: As a road test, Subject 3 has 16 tasks, with the most common failures occurring in light operations, overtaking and lane changing, and pulling over. The reasons for failure include unfamiliarity with light operations, incorrect gear shifting, and inability to find the right spot when pulling over.

Is it illegal to stick a national flag on a car?

Sticking a national flag decal on a car is legal, but it must not be used as a trademark or advertisement. Here are the specific details about car decals: 1. Posting requirements: Displaying the national flag reflects patriotic spirit. Article 18 of the National Flag Law clearly stipulates that damaged, stained, faded, or non-standard flags must not be hoisted. 2. Policies and regulations: Article 13, Section 3 of the Implementing Regulations of the Road Traffic Safety Law states: Identification marks or body advertisements sprayed or pasted on motor vehicles must not affect safe driving. Therefore, when car owners stick national flag-style decals on private cars, they must choose standard and compliant ones, and ensure they do not affect their own or others' normal driving.
