What Causes Loud Noise Inside the Car?

What does the yellow exclamation mark in Magotan mean?

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system fault. Below is a detailed analysis of these four situations: General malfunction: A triangle with an exclamation mark inside indicates that the car's general performance or certain components and functions have malfunctioned. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor malfunction, etc. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating that there is a fault in the transmission or the transmission lubricant level is below the normal range. The transmission oil should be replaced promptly. Abnormal tire pressure: A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light. This light will illuminate when the tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting system fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling that a car light has malfunctioned. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the issue. There is also a red exclamation mark inside a circle with a bracket, which represents a brake system warning, mainly indicating brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents.

How to Check the Date on New Car Tires?

On the sidewall of the tire, locate a string of characters starting with the English letters "DOT". At the end of these characters, there will be a four-digit number enclosed in an oval border, which indicates the tire's production date. The first two digits represent the week of the year the tire was produced, while the last two digits indicate the production year. Below is relevant information about tire maintenance: 1. Daily tire pressure checks. Avoid having tire pressure that is too high or too low. Overinflated tires may risk a blowout under high-speed operation due to inability to withstand excessive expansion pressure, while underinflated tires can cause excessive stretching from uneven road surfaces during driving, keeping the tires in a prolonged fatigue state and accelerating aging. 2. Regular tire rotation. Cross-rotating the front and rear tires ensures even wear across all four tires and provides better friction between the front wheels (steering drive wheels) and the road surface, preventing front-wheel slippage and ensuring driving safety. 3. Regular balance checks. Periodic balance testing not only extends tire life but also improves driving stability. 4. Timely replacement. The recommended lifespan for tires is approximately 40,000 kilometers. In very good road conditions, this can be extended to 60,000 kilometers, but tires older than two years should also be replaced.

Is it necessary to replace a faulty fuel level sensor?

Replacing a car's fuel level sensor can be challenging: 1. A malfunctioning fuel gauge is usually caused by a damaged fuel float, which is the fuel level sensor located inside the fuel tank. Replacing it requires opening the fuel tank; 2. In sedans, it's typically found either under the rear seats or inside the trunk. There's a small cover that, when opened, reveals the fuel float and fuel pump. If the fuel cap isn't securely sealed after replacing the float, gasoline can easily evaporate from there, leading to a stronger fuel odor; 3. The fuel gauge measurement works by a float connected to a metal rod, whose end is attached to a movable contact point on a variable resistor. The position of the float on the fuel surface in the tank changes, altering the position on the variable resistor via the metal rod. This variable resistor is connected to the fuel gauge, and the movement of the gauge's needle is controlled by the amount of current passing through the variable resistor.

Can You Still Drive with a Leaking Fuel Tank?

You should not drive with a leaking fuel tank. Here are the reasons for fuel tank leakage: 1. Reason one: Car fuel leakage is usually caused by overfilling the tank, preventing excess gasoline from burning in the form of vapor. 2. Reason two: Fuel leakage can also occur during the replacement of the fuel filter. Since the fuel filter is located under the car, it's possible that some pipes may not be tightly connected during replacement, leading to fuel leakage under the car. 3. Reason three: Another cause of fuel leakage is improper installation of the fuel pump seal ring after refueling or damage to the fuel pipes. When encountering poor road conditions, this can result in fuel leakage.

What Does the Steering Gear Assembly Include?

Directional steering gear assembly is designed to amplify the force from the steering wheel to the steering linkage and alter the direction of force transmission. Its primary functions encompass three aspects: 1. Amplifying the torque from the steering wheel: making it sufficient to overcome the steering resistance torque between the steering wheels and the road surface; 2. Reducing the rotational speed of the steering drive shaft: enabling the steering pitman arm shaft to rotate, driving the pitman arm to swing so that its end achieves the required displacement, or converting the rotation of the drive gear connected with the steering drive shaft into the linear motion of the rack and pinion to obtain the necessary displacement; 3. By selecting different thread spiral directions on the screw (worm), achieving coordination between the rotation direction of the steering wheel and the steering wheels.

How Many Copies of the Personal Vehicle Purchase Invoice Does the Owner Receive?

For the vehicle purchase invoice, the owner retains the sixth copy. A standard vehicle purchase invoice is a computer-generated six-part invoice. The first copy is the invoice copy, the second is the tax deduction copy, the third is the tax payment copy, the fourth is the registration copy, the fifth is the accounting copy, and the sixth is the stub copy, which is the one the owner should keep. Below is additional information: 1. Vehicle Purchase Invoice: The first copy, the invoice copy, serves as the payment receipt for the purchasing unit (usually retained by the 4S store) and is typically brown in color. The second copy is the tax deduction certificate for the purchasing unit and is green. The third copy, the tax payment copy, is retained by the vehicle purchase tax collection unit and is purple. The fourth copy, the registration copy, is kept by the vehicle registration unit and is blue. The fifth copy, the accounting copy, is the accounting voucher for the selling unit and is red. The sixth copy is the stub copy retained by the selling unit and is black. 2. Invoice Information: (1) Vehicle details, such as the VIN, engine number, and model information. (2) Purchaser information, including name and ID number. (3) Dealer information. (4) Purchase price, VAT, and the actual vehicle price excluding tax.
