Why does the steering wheel become hard to turn when the car is driving through water?

What kind of engine oil is used in the new Santana?

New Santana generally recommends using original semi-synthetic engine oil with a specification of 5W-30. Engine oil is an important factor affecting engine performance and service life. The quality of engine oil must not only meet the requirements of the engine and exhaust purification system, but also match the fuel quality. Information about engine oil is as follows: 1. Engine oil is the lubricating oil used by the engine. It consists of base oil and additives. 2. The density of engine oil is about 0.91×10³ (kg/m³). It can lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is known as the 'blood' of the car.

What are the symptoms of a faulty ignition coil?

When the ignition coil fails, the following symptoms may occur: 1. Engine vibration: Once the ignition coil is damaged, as the spark plug fails to ignite the combustible gas mixture, it can easily cause engine misfire, resulting in severe vibration. If there are too many misfiring cylinders or two adjacent working cylinders misfire simultaneously, the engine may fail to start normally. 2. Increased fuel consumption and reduced power: Even if the ignition coil damage does not cause engine misfire, the weakening of the spark plug's ignition capability will still affect the combustion of the engine's combustible gas mixture, leading to adverse effects such as increased fuel consumption and reduced power. 3. Excessive carbon deposits: When the spark plug's ignition capability weakens, it can also cause incomplete combustion of the combustible gas mixture. The incompletely burned gas mixture produces a substance called carbon deposits, and the vehicle's exhaust may emit black smoke.

Where is the Buick Envision's cabin air filter located?

The Buick Envision's cabin air filter is located inside the glove box. To replace the cabin air filter, you need to first remove the glove box on the passenger side, take out the old filter, and install a new one. The Buick Envision's cabin air filter serves the following purposes: 1. Filters out solid impurities such as pollen and PM2.5 from the air; 2. Absorbs moisture, carbon dioxide, vehicle exhaust, odors, and ensures clean air in the cabin to prevent bacterial growth. 3. The recommended maintenance interval for the vehicle's cabin air filter is every 10,000 kilometers or approximately six months. If driving in areas with severe smog, it is best to replace it every three months.

How Many Liters of Windshield Washer Fluid Should Be Added to a Car?

When filling up the car's windshield washer fluid, it is sufficient to fill it to the maximum level. Due to the differences in various car models, the filling volume also varies. Some small cars generally require only 2 liters, while others may need up to 4 liters to reach full capacity. Typically, the volume of windshield washer fluid is mostly around 2 liters, meaning approximately 2 bottles are needed. Below is some relevant information about car windshield washer fluid: 1. Car windshield washer fluid, commonly known as windshield cleaning liquid, is a consumable item in car usage. High-quality windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. 2. Currently, there is a wide variety of windshield washer fluids available on the domestic market, which can be mainly categorized into three types: summer-use windshield washer fluid, winter antifreeze windshield washer fluid, and special-effect antifreeze windshield washer fluid. The summer-use variant is primarily used to remove insect residues from the windshield. It is important to choose the appropriate windshield washer fluid based on different climates and temperature conditions. Generally, car windshield washer fluids are divided into 0°C fluid for summer use and -20°C or -35°C fluids for winter use. 3. Car windshield washer fluid is widely used for quick dirt removal and bright cleaning of various types of glass, including car windshields, rearview mirrors, household glass, office glass, door and window glass, and decorative glass. It offers comprehensive performance, is easy to use, and can also be homemade.

Can engine oils of different brands be mixed together?

Engine oils of different brands should not be mixed together. Here are the relevant explanations: 1. Mixing engine oils may lead to the formation of flocculent substances, increased viscosity, and other issues. Engine oils from different brands may even undergo chemical reactions. 2. The additive components in engine oils from different manufacturers are completely different. The chemical compositions of various additives can vary significantly, not only between different brands but also between different product lines of the same brand. There is no guarantee that any two brands of engine oil will not react chemically under the high temperatures in an engine. However, it is certain that some combinations of engine oils will produce adverse reactions, such as the formation of flocculent substances or increased viscosity. 3. During maintenance, when changing to a different brand of engine oil, it is essential to drain the old oil from the engine as thoroughly as possible. Although it is impossible to ensure 100% removal, the cleaner the better. For gravity draining, it is best to let the oil drain for more than two hours.

Working Principle of Tire Pressure Monitoring in Golf 7

The working principle of tire pressure monitoring in Golf is: by utilizing ABS sensors to compare the rolling circumference and rotational speed of each wheel. If the tire pressure of one or more wheels changes, the tire pressure loss indicator in the combination instrument and infotainment system display will issue an alarm. More details about tire pressure monitoring are as follows: 1. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to tire leaks and low pressure to ensure driving safety. 2. There are two common types: direct and indirect. The advantage of a direct tire pressure monitoring system is that each wheel is equipped with a pressure sensor and transmitter. If the tire pressure of any tire is 25% lower than the recommended cold tire pressure in the driver's manual, it will alert the driver. 3. Its warning signals are more precise, and if a tire is punctured and the pressure drops rapidly, the direct tire pressure monitoring system can provide an immediate warning. 4. The indirect tire pressure monitoring device actually uses the speed sensors on the car's ABS braking system to compare the rotation counts of the four tires. If one tire has lower pressure, its rotation count will differ from the others. By using the same sensors and signals as the ABS system, the vehicle's computer can adjust the software to establish a new function in the driving computer, warning the driver that one tire's pressure is lower compared to the other three.
