What are the reasons for a gasoline water pump not pumping water?

Air has entered the clean water pipe and the water pump body, or there is a problem with the internal components. The following are specific symptoms of a faulty electronic water pump: 1. Overheating of water temperature: The car's cooling circulation capacity weakens or even stops circulating, leading to overheating of the water temperature, especially more noticeable in the southern summer. 2. Water pump leakage: The engine leaks near the water pump area. Leaking coolant will leave traces of coolant color on the water pump vent holes, leading to symptoms such as high water temperature due to lack of coolant. 3. Abnormal noise from the water pump: The water pump makes abnormal noises when the engine is running, which may be slight and difficult to detect.

I've been a car repair master for almost ten years, and there are several common issues when the fuel pump fails to deliver gasoline. The most likely scenario is that the fuel pump is completely burnt out, and you won't hear the humming sound under the rear seat when turning the key. It could also be a severe blockage in the fuel line, with the filter screen in the fuel tank clogged by debris. Additionally, a burnt fuel pump relay or a blown fuel pump circuit fuse can also cause a complete lack of response. The most troublesome issue is when the fuel tank's suction pipe ages and cracks, causing air leaks no matter how much you try to pump. In such cases, avoid forcing the ignition to prevent cylinder flooding. It's recommended to call a tow truck immediately for a shop inspection. Before removing the fuel tank, always remember to pull the fuel pump fuse to release pressure—otherwise, gasoline spraying everywhere is extremely dangerous.

Why does the steering wheel squeak when turning while the car is cold?

The reasons for the steering wheel squeaking when turning while the car is cold are as follows: Friction between plastic components: The steering wheel is composed of various plastic parts. If the gaps between these parts are too small, there may be abnormal noises when turning, especially in new cars. This usually resolves after a break-in period. If the noise persists after the break-in, try reinstalling the steering wheel. Friction between the steering column and the floor mat: Sometimes, the installed floor mat is too large and comes into direct contact with the steering column, causing friction when the steering column turns. This is quite common and can be resolved by adjusting or replacing the floor mat. Fault in the clock spring inside the steering wheel: Those who have disassembled the steering wheel should be particularly cautious. The issue might be a broken clock spring or a poorly connected clock spring plug. Replacing the clock spring or securing the plug can fix the problem.

What are the precautions for Subject 2?

Subject 2 precautions are as follows: Ensure adequate sleep: Make sure to get a good rest the night before the test to avoid involuntary nervousness or dizziness during the exam the next day. Mock test: The purpose of the mock test is to familiarize candidates with the exam environment and allow the instructor to point out areas prone to point deductions. Therefore, mock tests are absolutely essential—being well-prepared is the best way to face the challenge. Control speed when reversing into the garage: Don't go too slow, but don't let the car stop either. Find the reference point and reverse slowly to avoid going too fast, which may cause you to cross the line before you can turn the steering wheel back. Curve driving: The safest method during curve driving is to slow down, turn the steering wheel gradually, and observe the rearview mirror to avoid the rear wheels crossing the line.

What Causes the Humming Noise When the Car is Running?

The reasons for the humming noise when the car is running are as follows: Tensioner Pulley Wear: The function of the tensioner pulley is to keep the engine belt tight, preventing the alternator and power steering pump from slipping. Due to prolonged pressure and high-speed rotation, the bearings inside the tensioner pulley are prone to wear, resulting in noise and resonance. If the inspection confirms that the humming noise and resonance are caused by the tensioner pulley, it is also necessary to check the engine mounts, as their role is to reduce the vibration and noise generated by the engine. Exhaust Pipe Deformation: In most front-engine vehicles, the exhaust pipe runs from the bottom of the car to the rear. Driving on rough roads or hitting the undercarriage can easily cause the exhaust pipe to dent or deform. A deformed exhaust pipe increases exhaust resistance, leading to a humming noise and a sense of resonance.

How Many Days in Advance Can You Schedule the Subject 2 Driving Test?

You can schedule the Subject 2 driving test 3 days in advance (excluding weekends). This means that as long as you have completed the required training hours, you can schedule the test for as early as three days later. Whether the test appointment is successful or not, candidates will receive a corresponding SMS notification. Subject 2 Scheduling Tips: The system prioritizes applicants based on the chronological order of their business acceptance time, last test time, and last test cancellation time, with the earliest of these three dates determining the scheduling priority. Mastering these tips can make scheduling much more efficient. Subject 2 Test Content: For the C1 license, the test includes five mandatory items: reverse parking, parallel parking, hill start, right-angle turn, and curve driving (commonly known as the S-curve). Some regions may also include a sixth item: highway toll card collection. For the C2 license, the test includes four mandatory items: reverse parking, parallel parking, right-angle turn, and curve driving (commonly known as the S-curve).

What to Do When the Passat Emission Warning Light Comes On?

Start and turn off the vehicle three times in a row, or you can disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. The emission system warning light often comes on due to damage to the oxygen sensor in the three-way catalytic converter, which is mostly caused by the quality of domestic fuel. If the warning light comes on and the vehicle cannot start after being turned off, this is usually due to a malfunction in the fuel pump or ignition system. In such cases, call for a tow truck directly. If the light comes on while driving, immediately reduce speed and drive to the nearest repair service station for inspection.

How to Remove Paint Overspray?

You can use a high-efficiency paint remover to wipe away paint spots on the car window glass. Wear gloves and a mask before use, and shake the product well. Avoid direct contact with skin. If accidentally splashed into the eyes, rinse immediately with plenty of water. If inhalation causes vomiting, seek medical attention immediately. Take out a clean cloth or lint-free towel and spray the cleaner onto the towel. Use the towel sprayed with cleaner to repeatedly wipe the paint spots on the glass. After wiping clean, rinse the car glass with water and then wipe it dry with a clean towel. This will remove the paint spots on the window.
