How to Repair a Slightly Cracked Car Windshield?

What Causes Car Shaking at Idle?

There are several main reasons for car shaking at idle: 1. Poor combustion in the cylinders: Poor combustion results in insufficient power output, causing the car to shake. 2. Low ignition energy: The primary issue during cold starts is low temperature. When the engine temperature is insufficient, both fuel and lubricant temperatures are inadequate, requiring additional fuel injection during cold starts to meet power demands. 3. Excessive spark plug gap: With prolonged use, the ignition gap of spark plugs tends to widen, leading to decreased ignition energy. This affects power output and causes the car to shake.

How to Check the Production Date from Car Glass?

Here's how to check the production date of car glass: 1. The number represents the production year of the glass, indicating the last digit of the year. 2. The black dots indicate the production month of the glass. Some glass has dots before the number, while others have dots after the number. 3. If the dots are before the number, subtract the number of dots from 7; if the dots are after the number, subtract the number of dots from 13. The result is the production month of the glass. 4. Some glass may also have a few thick black dots added before the production year and month, which are used to specify the week of the month.

How Often Should Brake Pads Be Replaced?

There is no fixed interval for replacing brake pads, as it depends on driving conditions and habits, which can affect the wear of brake pads. The following situations indicate when brake pads need to be replaced: 1. Regularly check the thickness of the brake pads. If the thickness is less than 3mm, it's time to replace them. 2. When the dashboard displays a brake pad warning message, it indicates that the brake pads need to be replaced. 3. If the car shifts or drifts when braking, it suggests that the brake pads are worn and need replacement.

What are the symptoms of timing chain skipping teeth?

If the engine timing chain is not regularly maintained and adjusted, timing belt skipping may occur, leading to issues such as difficulty starting the engine and poor acceleration. The main causes of timing chain skipping teeth are as follows: 1. The belt comes into contact with oil: Since the timing belt is a rubber component, it should be kept clean during use and maintenance. If it comes into contact with oil or other solvents, the belt can corrode and deform, causing slippage and skipping teeth. 2. Failure to promptly inspect and adjust the timing belt tension: After a certain mileage, the timing belt naturally stretches. If the tension is not adjusted in time, skipping teeth can easily occur.

How to Read the Date on Car Glass?

There is a code on the lower left or right corner of the car window glass. The last or second last row contains a number and several black dots, which indicate the production date of the glass. The following details the method to check: 1. The number represents the production year of the glass, indicating the last digit of the year. 2. The black dots represent the production month of the glass. Some glasses have the black dots before the number, while others have them after the number. 3. If the black dots are before the number, subtract the number of dots from 7; if the black dots are after the number, subtract the number of dots from 13. The result is the production month of the glass.

How Long Should You Wait Between Subject 3 and Subject 4 Exams?

After passing Subject 3, the timing for taking Subject 4 falls into three scenarios: taking it directly on the same afternoon; within 9 days without an appointment—you can take the Subject 4 exam at the designated location within 9 days after passing Subject 3 by presenting your ID; or scheduling after 10 days, where the success of the appointment depends on the current number of examinees, the priority of the student, and temporary arrangements at the test center. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. It includes requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes, and making mistakes totaling 12 points (6 questions) will terminate the session. Number of Questions: Depending on the type of driver's license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank—800 questions for car licenses and 1,023 for large vehicle licenses, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also features animation questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: Failing Subject 4 only requires retaking Subject 4. The driving school schedules the retake, with no limit on the number of attempts, and no additional fees are required for retakes. Subject 4 Exam Tips: Strengthen weak areas by identifying the reasons for mistakes. For marked questions, avoid merely memorizing the correct answers. Instead, consult regulations, textbooks, or reference materials to understand and internalize the reasons behind the errors. Categorize and summarize questions by referring to the question bank's analysis to find similar questions. Many questions in the bank are similar and easily confused, so it's essential to analyze and group them. For example, traffic signs for walking, hiking, pedestrian crossings, and pedestrian warnings have similar patterns and can be confusing. Grouping them during study helps avoid mistakes. Use memory techniques: Many questions involve numbers, which can be summarized for easier recall. The driving test consists of three main subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 4 is the colloquial term for the Subject 3 Safety and Civilized Driving Knowledge Test and is not a separate subject. Subject 1 covers road traffic safety laws, regulations, and related knowledge; Subject 2 is the field driving skills test; and Subject 3 includes road driving skills and safety and civilized driving knowledge. The Safety and Civilized Driving Knowledge Test is conducted after Subject 3.
