What to Do When the Car Tail Light is Cracked?

If the car tail light is broken, it needs to be replaced immediately. The replacement steps are as follows: 1. Disconnect the power: For safety, always disconnect the power first. Open the car's trunk lid and cut off the vehicle's power to ensure no electrical operation afterward. 2. Remove the dust cover on the back of the tail light: This is a necessary step for tail light replacement. Remove the dust cover to facilitate the replacement process. 3. Perform the replacement: Before replacing the tail light, identify the specific light that needs to be replaced. Press and hold the rotating handle at the back of the light and unscrew it. Then, install the new light, paying attention to the model and color. 4. Reinstall the tail light and dust cover: After installing the new tail light, reattach the dust cover.

What Causes Water Leakage Under the Co-Driver Seat in a Car?

Water leakage under the co-driver seat in a car is likely caused by a door leak. Below are related explanations regarding water leakage under the co-driver seat: Solutions: If you hear obvious water sloshing sounds when opening/closing the door or while driving, it indicates water accumulation inside the door. In this case, simply use a thin wire or small screwdriver to unclog the drainage holes—this can be easily done yourself. Detailed scenarios of leakage: If the window regulator has been replaced, it may be due to improper adhesion of the door waterproof membrane after the replacement, as the membrane needs to be peeled off during the regulator replacement process. If the waterproof membrane is not properly sealed, heavy rain can cause water to enter the cabin. You can either reseal it yourself or replace the waterproof membrane.

What are the manifestations of mild fatigue in Subject 4?

Manifestations of mild fatigue in Subject 4: Frequent yawning and heavy eyelids. Below are detailed introductions about Subject 4: 1. Examination Subjects: The subjects of the driver's license test are uniformly set nationwide, divided into four subjects: theoretical knowledge, field driving skills, road driving skills, and civilized driving-related knowledge. Subject 4, also known as the Subject 4 theoretical test or driver's theoretical test, is part of the motor vehicle driver's license assessment. 2. Meaning: After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts, adding a safety and civilized driving knowledge test besides the road test. 3. Test Composition: The test paper consists of 50 questions, mainly in the form of cases, pictures, animations, etc., with a full score of 100 points, and a passing score of 90.

Where to Check the Study Hours for Subject 4?

Students can find the learning website on their study hour card, where they can check the study hours for Subject 4. Below is some information about the study hours for Subject 4: 1. Study Hours: For ordinary C1, C2, and C5 driver's licenses, the study hours for Subject 4 are 10 hours; for A1, A2, and B1 licenses, it's 16 hours; and for A3 and B2 licenses, it's 20 hours. Each study hour is 60 minutes, with effective teaching time not less than 45 minutes. 2. Subject 4 Scheduling: Generally, Subject 4 can be scheduled three days after passing the Subject 3 test. In some places, students can even take Subject 4 directly on the same day they pass Subject 3 without prior scheduling and receive their license immediately. However, specific arrangements may vary depending on the local vehicle management office.

What are the functions of fuel additive?

Here are the functions of fuel additive: 1. Clean the fuel system. After continuous use, carbon deposits on the exhaust pipe are significantly reduced, and the filter, exhaust valve, fuel system, etc. are very clean. 2. Enhance power performance. It causes secondary atomization of fuel, leading to complete combustion and improving engine power. 3. Improve atomization. It increases thermal efficiency and reduces fuel consumption. 4. Protect the engine. It has functions such as anti-oxidation, cleaning, dispersion, demulsification, anti-corrosion, and lubrication. 5. Reduce wear. It lowers engine noise and extends the engine's service life. 6. Reduce emissions. Gasoline additives can effectively reduce the activation energy of combustion, allowing non-combustible colloids in the fuel to fully burn. Fuel additive, commonly known as gasoline additive or fuel additive, is designed to compensate for certain deficiencies in gasoline and endow it with new excellent characteristics. It has effects such as cleaning system carbon deposits, increasing octane number, improving atomization, reducing wear, and protecting the engine.

What Are the Symptoms of a Broken Car Radiator Cap?

When the car radiator cap is broken, coolant will spray out from the radiator cap, reducing the flow of coolant into the engine and lowering the pressure. As a result, the heat generated by the engine cannot be dissipated by the coolant, leading to engine overheating or even boiling over. The functions of the radiator cap are as follows: 1. Sealing. Under any operating condition, coolant leakage through the radiator cap is not allowed. 2. When the coolant temperature rises and the pressure inside the radiator increases to a certain value, the radiator cap automatically opens the pressure relief valve, allowing excess coolant due to thermal expansion to flow into the auxiliary tank. 3. When the coolant temperature decreases, due to the contraction of the coolant, a negative pressure forms in the radiator, and the radiator cap automatically opens the return valve, allowing the supplementary fluid in the auxiliary tank to flow back into the radiator.
