How Long Before a Car Becomes a Stock Vehicle?

Stock vehicles generally refer to cars that remain unsold for more than three months after being manufactured and leaving the factory. Here are some considerations when purchasing a stock vehicle: 1. Check the paintwork. Most brand 4S stores keep stock vehicles outdoors, where the car bodies tend to get quite dirty. It is advisable to have the 4S store wash the car thoroughly before conducting a detailed inspection of the paintwork to look for scratches and dents, as minor scrapes can occur during various movements of stock vehicles. 2. Inspect rubber materials such as tires and sealing strips. Rubber is highly susceptible to external influences. Across different seasons, factors like temperature, humidity, exposure to sunlight, acidic rain, and freezing conditions in snowy weather can all impact the lifespan of rubber components. Therefore, carefully check for signs of aging in the vehicle's rubber parts, including critical components like tires, engine belts, and windshield wipers. 3. Examine the mechanical condition. Naturally, this involves checking the engine. A well-functioning engine should have no oil stains on its exterior, respond quickly and sensitively when started, run smoothly without shaking, produce even sounds without sharp or irregular noises. When cold, the idle speed should be slightly higher, around 1,000 RPM as indicated by the tachometer. Once the engine warms up, the idle speed should drop to approximately 780 RPM. At this point, lightly pressing the accelerator should result in a swift response, free from knocking or loose sounds. Placing a hand on the engine cover should reveal no significant vibrations, and when seated inside the car, the engine noise should be barely audible. 4. After verifying the fluid levels of the engine's three oils and two liquids (three oils: engine oil, brake fluid, power steering fluid; two liquids: coolant, windshield washer fluid), proceed to inspect the battery. For new cars, observe the battery status indicator. A green indicator signifies that the battery is in good condition with sufficient charge, while black or white indicates insufficient charge or potential damage, necessitating prompt recharging.

What are the reasons for an automatic transmission car stalling at startup?

Common reasons for an automatic transmission car stalling are as follows: 1. Circuit failure, possibly due to low-voltage power outage or quenching during driving. In this case, mainly check the ignition switch, start switch, and fuse box. Stalling caused by a short circuit in the low-voltage circuit is intermittent, so inspect the vehicle's low-voltage lines. 2. Equipment failure, usually related to the ignition coil, capacitor, or electronic ignition module. The car may start initially but stall after a while, then restart only to stall again. 3. Fuel system failure, such as a damaged fuel pump, ruptured pipeline, clogged carburetor inlet, or empty fuel tank. In such cases, the car can be restarted but with difficulty. Problems with the ignition system or engine overheating and anti-knock system can also cause stalling. Steps to take after stalling: 1. For an automatic transmission car, immediately turn on the hazard lights to alert following vehicles when stalling is detected. 2. Step on the brake to stop the car as quickly as possible, then turn the key to restart. Stalling may be due to issues with the engine speed sensor or excessive dirt, problems with the idle control program in the engine electronic control unit, or fuel quality issues may also cause stalling.

What are the steps for applying solar film?

The steps for applying solar film are as follows: 1. Wash the car. Ensure the working environment is clean and thoroughly clean both the inside and outside of the car windows to avoid affecting the subsequent installation. 2. Cut the film. Cut the film to the appropriate size according to the glass, slightly larger if needed, but never smaller, as it will shrink a bit after being blown by a heat gun. 3. Lay the film. Typically, automotive solar films consist of a protective layer and the film itself. Before application, spray some water on the glass and also on the adhesive side of the film to reduce its stickiness, making it easier to adjust and align the film. 4. Shape the film. Since car windows have a certain curvature, use a heat gun to shape the film. During the heating process, control the temperature and movement speed of the heat gun to avoid prolonged exposure to one area, ensuring no damage occurs. 5. Apply the film. After shaping, proceed with the installation. Spray some cleaning solution on the inner side of the glass and also on the adhesive side of the film. Once aligned, begin the formal application.

Why Did the Car Battery Suddenly Lose Power?

Reasons for a car suddenly losing power are as follows: 1. Battery aging "strike"; 2. Frequent stops and starts during short trips; 3. The car being parked for too long during holidays; 4. Multiple failed starts in low-temperature environments; 5. Frequent car starting; 6. Engine failure preventing charging; 7. Forgetting to turn off the air conditioning before shutting down the engine; 8. Forgetting to turn off lights and in-car electrical appliances; 9. Listening to high-power audio while idling. Precautions for a car losing power are as follows: 1. Avoid frequent starts. Some people keep trying to start the car if it doesn’t start within three to five seconds. Instead, wait for a while before trying again, as starting the car puts significant pressure on the battery, and frequent starts can greatly affect battery discharge and reduce its lifespan. 2. Turn off all electrical appliances before shutting down the engine. Some drivers often forget to turn off the car lights after shutting down the engine, leaving them on all night. The next day, they find the doors won’t open and the engine won’t start. However, most modern cars now have an automatic power-off function after shutting down, greatly reducing the occurrence of such situations.

Can I change to the C2 test after passing the C1 subject one?

After passing the C1 subject one, you can change to the C2 test. Before scheduling the subject two test, you can apply to switch from C1 to C2, which requires resubmitting the application form and medical examination certificate. When changing from C1 to C2, the previously passed subject one score will be invalidated, and you will need to pay for the subject one training and examination fees before reapplying for C2. The specific requirements depend on the driving school's regulations. Subject One: Traffic regulations and related knowledge, also known as the written test, is scored out of 100, with 90 or above being a passing grade. Subject Two: Field driving, also known as the closed-course test, is conducted in a real vehicle. It is only graded as pass or fail. There are nine mandatory test items, including reverse parking in a garage, narrow road U-turns, parallel parking, stopping and starting on a slope, right-angle turns, curve driving, emergency braking, tunnel driving, and toll booth card collection. All nine items must be passed to successfully complete the subject two test.

Is There a Difference Between Gasoline and Diesel Antifreeze?

Automotive antifreeze is universal and does not differentiate between diesel and gasoline engines. Here are some relevant details: 1. Antifreeze is categorized into light-duty and heavy-duty vehicle types. Heavy-duty vehicle antifreeze can be used in light-duty vehicles, but light-duty vehicle antifreeze cannot be used in heavy-duty vehicles. Additionally, different brands of antifreeze may have varying production formulas, which can lead to chemical reactions if mixed, so they should not be combined. 2. Antifreeze, short for antifreeze coolant, primarily consists of ethylene glycol and is used for maintaining the engine cooling system. It is also important not to mistakenly believe that antifreeze is only for winter use; vehicles require antifreeze year-round. Beyond preventing freezing, antifreeze has other main purposes: (1) Corrosion and rust prevention: Some metal components in a car can corrode over time, which directly affects the lifespan of the cooling system. Using water instead of antifreeze will only worsen this issue. (2) According to surveys, over 70% of automotive cooling systems suffer from scale and rust buildup, leading to issues like overheating, water shortage, cylinder sticking, and bearing wear. Antifreeze is essential for preventing these problems.
