What is the minimum speed for Subject 3?

There is no specific requirement, but generally, driving on the road should be within 30km/h, and second gear is appropriate. Below is more related information: 1. First gear: Typically used when starting or climbing a slope, the driving speed in this gear is around 10km/h. Conversely, if the current speed is around 10km/h, you can shift to first gear to avoid being identified as having a speed-gear mismatch. 2. Second gear: A transitional gear for acceleration after starting, used for low-speed forward movement or climbing small slopes. The speed in this gear is generally around 20km/h. 3. Third gear: Usually used when driving on urban or rural roads, the speed should be between 20-40km/h. 4. Fourth gear: When the speed is between 40-60km/h, you can shift to this gear. Generally, the Subject 3 test involves shifting from first gear up to fourth gear and then back down from fourth gear to first gear, rarely using fifth gear. 5. Fifth gear: Used at speeds above 60km/h, typically when driving on highways.

Why Does Coolant Change Color?

The specific reasons for coolant discoloration include prolonged usage leading to oxidation reactions, contamination with other liquids, or deterioration and impurity accumulation in the coolant. When coolant discoloration is observed, it is recommended to replace the coolant promptly. A fading color indicates that the coolant has begun to deteriorate. The main components of coolant are 50% pure water, 40% methanol, and 10% other substances. Coolants are generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water. Method for Replacing Coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with particular attention to the five-way hose. The five-way hose is named for its five connecting interfaces that distribute coolant to different parts of the vehicle. If leakage is detected in this section, replace the hose or resecure the connections as needed. Drain the old coolant and flush the liquid channels with clean water. Add water to the coolant reservoir and continue filling until clean water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Continue flushing until the water runs clear. Note: Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, add the new coolant through the radiator hose to facilitate rapid flow into the radiator. Then, fill the coolant reservoir with another batch of coolant until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels air, the coolant level will drop. Top up the coolant to the "MAXT" mark on the reservoir.

What Causes a Gasoline Smell in the Car's Air Conditioning?

The reasons for a gasoline smell in the car's air conditioning are component failure and overfilling of gasoline. Below are detailed explanations: 1. Component failure: The car's fuel supply system is a closed system, and gasoline vapor generally does not escape. However, if a certain part malfunctions or is used improperly, gasoline vapor can escape from this part, leading to a gasoline smell in the engine compartment. If the charcoal canister fails, for example, the charcoal canister solenoid valve cannot open properly, gasoline vapor cannot enter the engine for combustion. When the charcoal canister absorbs too much gasoline vapor, for safety reasons, the gasoline vapor will be released into the atmosphere. 2. Overfilling of gasoline: The gasoline tank is filled too full. The charcoal canister is connected to the top of the gasoline tank through a vent pipe, which normally contains gasoline vapor. If the gasoline is overfilled, this vent pipe can become filled with liquid gasoline, and even the charcoal canister can become saturated with gasoline. In this case, the charcoal canister cannot function properly, and gasoline will escape into the engine compartment.

What to Do If You Forgot Your ID Card for Subject 4 Exam?

If you don't have your ID card, you can first apply for a temporary ID card, which can be used to take the exam. The Subject 4 exam consists of 50 questions, mainly in the form of case studies, pictures, and animations, with a full score of 100 and a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Because this test is conducted after Subject 3, it is commonly called the Subject 4 exam. Officially, there is no such term as Subject 4. If you fail Subject 4, you don't need to retake the previously passed subjects (Subject 1, Subject 2, and Subject 3). You can schedule a retake on your own, and no retake fee is required. There are no scheduling restrictions, but the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within the validity period, the passed subject scores will be invalidated.

How to Deal with Foggy Car Windows When Using Air Conditioning?

When fog forms on the outside of car windows while using air conditioning, you can slightly open both side windows to allow air circulation. This helps eliminate the temperature difference on both sides of the windshield, making it difficult for fog to form. Alternatively, turning on the cold air from the air conditioning can quickly remove the fog. Both methods are effective in providing quick results, but they are not suitable for prolonged use in cold weather or during rain or snow. Here are more related solutions: 1. Use warm air: While cold air provides a quick but temporary solution, warm air can fundamentally solve the problem of foggy windows. The fog won't return after turning off the warm air, and it won't make the car's interior even colder during winter. However, the main drawback of using warm air is its slow effect, requiring a long waiting time to see results. Additionally, using warm air while driving consumes more fuel, making it a bit costly. 2. Anti-fog spray: You can use an anti-fog spray. The principle is simple—spraying a layer on the windshield forms a protective film that prevents water vapor condensation. However, the effectiveness of this protective film is short-lived, requiring frequent reapplication to maintain the effect.
