How often should power steering fluid be changed?

Power steering fluid should be changed every 2 years or 40,000 kilometers. If the car uses an electric power steering system, there is no need to change the power steering fluid because the electric power steering system does not require power steering fluid at all. Only electro-hydraulic power steering systems and mechanical hydraulic power steering systems require power steering fluid. Both electro-hydraulic power steering systems and mechanical hydraulic power steering systems have a power steering pump and hydraulic mechanisms. The power steering pump in an electro-hydraulic power steering system is driven by an electric motor, while the power steering pump in a mechanical hydraulic power steering system is driven by the engine. Cars with electric power steering systems have lighter steering wheels, and the steering ratio and the level of steering assistance can be adjusted. Cars with hydraulic power steering systems have heavier steering wheels, but the hydraulic power steering system provides more direct feedback from the road, which is why many driving and handling enthusiasts prefer hydraulic power steering systems.

Why does the reversing radar keep beeping?

The reasons why the reversing radar keeps beeping are: 1. There is an obstacle near the reversing radar sensor that blocks the sensor, and the reversing radar system will continuously alert through images or sounds. In this case, simply remove the obstacle; 2. The reversing radar sensor is damaged. If any sensor in the reversing radar system has a problem, it will continuously prompt. In this case, locate the damaged reversing radar sensor and replace it; 3. Control unit issues. The likelihood of the controller itself being damaged is low, but since the control unit is installed in a special location in many car models, it is particularly prone to being burned due to external water leakage. In this case, after confirming the control unit is damaged, it is essential to identify the cause of the water leakage to avoid damaging the control unit again after replacement; 4. Problems with the front and rear buzzers or wiring of the reversing radar. Depending on the situation, replace the buzzer or repair the wiring harness.

How to Check the Production Date of a Tire?

Method to check the tire production date: The manufacturing date of a tire can be found on the outer sidewall of the tire. There is a group of four digits in an elongated oval shape at the end of the letters. The first two digits represent the week of the year, and the last two digits represent the year. Sometimes these corresponding marks cannot be found on the tire because it was installed incorrectly, causing it to be mounted in reverse. Tires are circular elastic rubber products assembled on various vehicles or machinery for rolling on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. Tires serve as the medium for transmitting forces between the vehicle and the road, transferring driving force, braking force, steering force, etc., thereby enabling the vehicle's driving, braking, and steering operations.

What does the AC button on the car mean?

The AC button on the car refers to the air conditioning system. Pressing the AC button activates the air conditioning to adjust the temperature according to the set level, while turning it off only allows the fan to operate. The car air conditioning system, commonly known as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to maintain a stable and comfortable environment for passengers, reducing travel fatigue. Based on performance, car air conditioning systems can be divided into two types: single-function type (where the cooling, heating, and ventilation systems are installed separately and operate independently without interference, typically used in large buses and trucks) and combined heating-cooling type (where cooling, heating, and ventilation share the same blower and air ducts, controlled via the same panel). During operation, they can be further categorized into combination-type (where heating and cooling work separately) and mixed temperature-control type (where heating and cooling can work simultaneously).

Is It Normal for a Car's Exhaust Pipe to Have Black Soot?

It is normal for a car's exhaust pipe to have black soot. Any gasoline-powered vehicle will develop black soot in the exhaust pipe over time. The black residue on the exhaust pipe is mainly caused by incomplete combustion of gasoline. This is not a malfunction—even if the engine achieves efficient combustion, it cannot be perfect. Therefore, unburnable impurities in the gasoline will be expelled and accumulate in the exhaust pipe, forming black soot. For example, if you accidentally use low-quality gasoline with more impurities, combustion efficiency will inevitably decrease. Additionally, factors such as poor local air quality, haze, or strong winds affecting air intake, or prolonged idling during warm-up can impact gasoline combustion efficiency, making the exhaust pipe more prone to blackening. If the engine is turbocharged with direct fuel injection, the blackening process may occur even faster. These are all normal phenomena and do not require concern.

What is the R gear?

R refers to the reverse gear, which is engaged when reversing the vehicle. Common automatic transmission vehicles also have P, N, D, S, and L gears. P stands for Parking gear; N stands for Neutral gear; D represents Drive gear; S stands for Sport gear; and L stands for Low gear. Automatic transmissions do not require gear shifting while driving, offering the advantage of easier operation compared to manual transmissions. Automatic transmissions also include continuously variable transmissions (CVT), paddle-shift transmissions, and electronic gear lever transmissions. Vehicles on the market generally come with three types of transmissions: manual transmission, automatic transmission, and semi-automatic transmission. The correct way to start an automatic transmission car is to first move the gear selector to the intended driving position before pressing the accelerator pedal. Avoid pressing the accelerator abruptly; instead, press it gently and accelerate gradually.
