At what level of tire cracking must replacement be done?

Tires must be replaced when the remaining groove depth of the tread is below 1.6 millimeters. Here are some methods to protect your tires: 1. Avoid hitting curbs and falling into potholes. Some car owners have a rather aggressive parking style, preferring to park with their vehicles straddling the curb. During this process, the tires are subjected to compression, which can easily cause the sidewall cords to break, leading to tire bulges. 2. Avoid scraping the tire sidewalls. Often, sidewall scrapes occur unintentionally when parking near the curb or due to driver distraction. The sidewalls are the weakest part of the tire, and severe wear can also cause bulges, increasing the risk of a blowout. Therefore, when parking near the curb, drivers should pay attention to the distance between the vehicle and the curb to avoid scraping the sidewalls. 3. Do not reduce tire pressure in summer. Many car owners mistakenly believe that reducing tire pressure in summer can prevent blowouts due to high temperatures. However, this increases the contact area between the tire and the ground, raises friction, accelerates tire wear, and causes the tire temperature to rise more quickly, making blowouts more likely. Therefore, maintaining normal tire pressure in summer is still essential.

What are the symptoms of low coolant in a car?

When the vehicle's coolant is insufficient, the water temperature warning light will illuminate while driving. This light, which resembles two wavy lines with a thermometer, indicates that it's time to add more coolant. Coolant replacement method: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The five-way hose gets its name from having five connection points to different parts of the vehicle. Coolant flows through the five-way hose and is distributed to various parts of the car to perform its function. If there is any coolant leakage in this area, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the channels with clean water. Add clean water to the coolant reservoir, then continue adding water to ensure a continuous flow through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Continue adding clean water until the drained water runs clear. Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, add another container of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant to the "MAX" mark on the reservoir.

What is the difference between No. 92 diesel and gasoline?

No. 92 diesel and gasoline differ in the following aspects: 1. Volatility. Gasoline is highly volatile, whereas diesel is difficult to volatilize. As a result, gasoline vehicle pollutants include fuel evaporation emissions, whose components are hydrocarbons (HC). 2. Ease of mixing with air. Gasoline readily mixes with air and tends to stay mixed, allowing gasoline and air to combine uniformly with minimal occurrences of localized over-rich or over-lean mixtures or liquid fuel droplets. In contrast, diesel mixes unevenly with air, inevitably leading to localized oxygen deficiency or excess. When fuel is subjected to high temperatures and oxygen deficiency, it tends to carbonize, forming soot. Diesel combustion also produces some odorous organic gases, which is why diesel engine emissions have a distinct smell.

What Lights to Use When Driving in Fog?

When driving in fog, it is necessary to turn on the fog lights. Precautions for driving in heavy fog: 1. The appropriate lights must be turned on. Because visibility is poor when driving in fog, it is difficult to see the vehicles ahead without turning on the lights, which can easily lead to rear-end collisions or crashes. Extra caution is needed, especially in turning areas. According to relevant safety regulations, when driving in heavy fog, you should turn on the fog lights, hazard warning flashers, and low beams. Additionally, in foggy, rainy, or snowy weather, you should also turn on the low beams, clearance lights, and rear position lights. 2. Use the horn appropriately when driving in fog. Sometimes visibility is extremely poor, so in dangerous areas, honking the horn briefly can alert vehicles or pedestrians ahead to be cautious. Of course, avoid continuous honking to prevent noise pollution. 3. Slow down. Because distant vehicles are hard to see in foggy conditions, driving too fast may not leave enough time to brake if a vehicle suddenly appears. Also, maintain a safe following distance. In heavy fog, even the car directly ahead may be hard to see, increasing the risk of rear-end collisions.

What is the method for measuring the quality of an ABS sensor?

Operation method for testing the quality of an ABS sensor with a multimeter: Connect the red probe to Output and the black probe to GND, then bring an object close to the infrared receiver light to observe if the voltage changes normally. Measure the VCC voltage with power on to check if it is normal. If normal, it indicates that the car's ABS sensor is functioning properly. Otherwise, it is abnormal. Here is an introduction about ABS: 1. ABS automatically controls the braking force during car braking to prevent the wheels from locking up. 2. The ABS system consists of: ABS module, ABS master cylinder, oil pipes, wheel speed sensors, etc.
