What to Do When There's a Sour Smell from the Car Air Conditioner?

Car air conditioners emitting a sour smell may be due to unclean air filters, dirty air ducts, or accumulated dust on a damp evaporator. Relevant explanations are as follows: 1. A large amount of impurities and dust can generate various molds harmful to human health. Besides timely cleaning of the evaporator (the air conditioning system is generally cleaned once a year, preferably before summer), it is also recommended to replace the air filter and clean the air conditioning system. 2. Skillful use of the air conditioner can effectively keep the evaporator dry, reducing the breeding of bacteria and mold. Timely replacement of the air filter is also a very effective method. Extended content: The function of a car air filter is to filter the air entering the car interior from the outside, improving air cleanliness. Common filtering substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust.

What Are the Consequences of Not Maintaining a Car?

The consequences of not maintaining a car include warranty voidance, paint corrosion, engine wear, oil degradation, filter clogging, tire aging, wiper hardening, wiring faults, and more. More detailed information is as follows: 1. From an external perspective, the car's paint is particularly vulnerable to damage, especially during the hot summer months when UV rays can corrode the paint. This can cause the car to lose its shine and appear aged. In more severe cases, the car's body may develop cracks. 2. If the air filter is not replaced in time, it can accumulate a lot of dirt, clogging the engine and causing ignition issues. Similarly, not replacing spark plugs after prolonged use can lead to ignition difficulties and even increased fuel consumption. 3. Tires will age, and if debris on them is not cleaned off, it can wear down the tires over time, potentially leading to blowouts.

How often should the transmission fluid be changed in a Passat?

The transmission fluid replacement interval for the Volkswagen Passat is every 50,000 kilometers. The methods for changing transmission fluid are as follows: 1. Gravity Drain: This works on the same principle as changing engine oil. After loosening the fastening nut at the bottom of the oil pan, the transmission fluid will automatically drain out through the drain hole. This is the most common and easiest method, but it doesn't completely remove all the old transmission fluid. Residual fluid often remains in mechanical grooves and recesses. 2. Machine Flush: New transmission fluid is added to a flushing machine, which connects to the transmission's fluid lines. The machine's function is to push out the old fluid with the new, achieving a complete replacement. This method cleans the fluid lines more thoroughly. The more new transmission fluid used, the cleaner the system becomes. A machine flush typically requires about 10-13 liters of transmission fluid and takes approximately 1 hour. 3. Oil Pan Removal: This method provides the most thorough replacement and cleaning, and also allows for cleaning or replacing the dirty filter. Removing the oil pan is a major task, and accordingly, the labor cost will be higher.

How to Use the Reversing Camera Correctly?

Correct usage of the reversing camera: When shifting into reverse gear, there are usually three colored auxiliary lines—red, yellow, and green—each representing different distances from the rear of the car. For example, the red auxiliary line indicates that when it touches an object, the distance is only 30 centimeters, and you should stop reversing immediately. The yellow auxiliary line indicates a distance of about 1 meter, allowing you to continue reversing but with caution and reduced speed. The green auxiliary line indicates a distance of about 2 meters, meaning you can reverse with confidence. Below are the steps and precautions for using the reversing camera: 1. When shifting into reverse gear, the reversing camera automatically activates. 2. The image displayed by the reversing camera is captured in real-time by the rear camera. However, due to distortion in the camera's imaging, it can easily lead to misjudgment of obstacle distances. Therefore, when assessing distance, it is best to rely on the more accurate feedback from the parking sensors. 3. Nowadays, almost all reversing cameras come with a reversing trajectory system. This system displays two dashed lines on the screen to simulate the wheel's movement path, which shifts according to the steering wheel's rotation. This feature allows for intuitive prediction of the wheel's trajectory, further enhancing parking safety.

What does 9AT stand for?

9AT represents the following meanings: 1. 9AT stands for a 9-speed automatic transmission, where AT represents a torque converter automatic transmission. Common automatic transmissions include AT transmissions, DCT transmissions, and CVT transmissions. Among these, AT transmissions are the most technologically mature and widely used. 2. The 9AT transmission controls different combinations of planetary gears through shifting elements to achieve a setup of 9 forward gears and 1 reverse gear. It utilizes nested planetary gears to reduce the length of the transmission body. By optimizing the transmission structure and using lightweight component materials that meet strength requirements, the overall weight is effectively controlled.

What Are the Normal High and Low Pressures for a Car Air Conditioner?

The normal high pressure for a car air conditioner should be 1.3-1.7MPa, while the low pressure should range between 0.1-0.25MPa. Below is an introduction to related content: When testing the high and low pressures of a car air conditioner, the low pressure should decrease as the engine speed increases when the throttle is opened. The faster the speed, the more (or quicker) the pressure drops, indicating good compressor performance. Conversely, it suggests a compressor malfunction. For example, if a chiller uses R22 refrigerant and operates with a high pressure of 1.8MPa, the corresponding condensation temperature is approximately 50 degrees Celsius.
