What Causes the Whistling Noise in a Car's Air Conditioning Expansion Valve?

An abnormal noise from a car's air conditioning expansion valve indicates that the expansion valve is clogged. A faulty expansion valve and a blocked system exhibit similar symptoms, such as poor cooling or heating performance, and in severe cases, no cooling or heating at all. Here are several types of internal noises in a car's air conditioning system: 1. A water-flow-like sound from the chassis: When the air conditioning is turned on, a noise resembling flowing water is heard from the chassis. This is the expansion valve operating normally. 2. Abnormal noise in the air duct: The air filter has not been replaced for a long time, or there are foreign objects like leaves in the air duct. 3. Air in the compressor: The presence of air or moisture in the refrigerant of the air conditioning compressor can cause abnormal noises during refrigerant evaporation and expansion.

Is It Okay to Sleep in a Car Without Starting It?

It is possible to sleep in a car without starting it. When sleeping, you should leave a small gap in the windows or sunroof to ensure proper air circulation inside the vehicle and avoid potential hazards. For resting inside a motor vehicle, you can fold down the rear seats to create more space and increase sleeping comfort. Below is more information about sleeping in a car: 1. Do not turn on the air conditioning while sleeping: If the air conditioning is on with the air recirculation mode activated, carbon monoxide emitted by the engine can enter the car through the air conditioning system. If the window gaps are too small, carbon monoxide can accumulate, leading to dangerous levels that may cause poisoning. 2. Install a car air filter: Those who frequently sleep in their cars should install a car air filter. It helps remove particulate impurities from the air inside the vehicle. A car cabin air filter effectively reduces pollutants entering through the heating, ventilation, and air conditioning (HVAC) system, preventing the inhalation of harmful contaminants. 3. Use the external air circulation mode: Keeping the internal air recirculation mode on for too long can lead to stale air and increased pollutants inside the car. Prolonged use of internal circulation can degrade air quality, reducing oxygen levels and worsening the overall air quality over time.

Can the car window be opened if the car falls into water?

No, opening the window would allow water to rush in, and failing to escape in time could lead to drowning. Additionally, the pressure difference between the inside and outside increases the friction between the glass and the window frame, making it very difficult to open the window. 1. Correct approach: When the water levels inside and outside the car are unequal, the car door cannot and should not be opened immediately. You must wait until the water levels inside and outside the car equalize before opening the door. It is also advisable to keep a window-breaking hammer inside the car for emergencies. 2. Principle: When a car falls into water and the water levels inside and outside are unequal—meaning the water level outside is higher than inside—the difference in water pressure between the inside and outside will create immense force, pressing the door shut. This makes it impossible to open the door. Even if you manage to open it, water from outside would immediately flood the car, trapping the occupants and causing the vehicle to sink rapidly.

Can I eat before the driving school physical examination?

Yes, fasting is not required for the driver's license physical examination. The driver's license physical examination should comply with the requirements of the national and local management authorities, and actively complete the relevant inspections. Physical examination requirements: Height: According to the latest Ministry of Public Security Order No. 139, there is no height requirement for Class C driver's licenses. For large passenger vehicles, tractors, city buses, large trucks, and trolleybuses, the height requirement is above 155 cm. For medium-sized passenger vehicles, the height requirement is above 150 cm. Monocular vision impairment: If the better eye has a naked or corrected visual acuity of 5.0 or above on the logarithmic visual acuity chart and the horizontal visual field reaches 150 degrees, a Class C driver's license can be applied for. (Note: Previously, monocular vision was not allowed for a driver's license, but the latest Ministry of Public Security Order No. 139 allows application if the above requirements are met.) Hearing: The ability to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork. Hearing aids are allowed for those with hearing impairments. Lower limbs: Both lower limbs must be sound and have normal motor function, with a length difference not exceeding 5 cm. However, if the left lower limb is missing or has lost motor function, a driver's license for small automatic transmission vehicles can be applied for. Right lower limb and both lower limbs: If the right lower limb or both lower limbs are missing or have lost motor function but the person can sit independently and the upper limbs meet the requirements of Item 6, a driver's license for small automatic transmission passenger vehicles for the disabled can be applied for. If one hand is missing but the other hand has a sound thumb and at least two other sound fingers, with normal upper limb and finger motor function, and the lower limbs meet the requirements of Item 7, a driver's license for small automatic transmission passenger vehicles for the disabled can be applied for. Vision: 1. For Class C driver's licenses, the naked or corrected visual acuity of both eyes must be 4.9 or above. Color vision: No red-green color blindness is allowed. Upper limbs: Both thumbs must be sound, and each hand must have at least three other sound fingers, with normal limb and finger motor function. However, if the fingers are missing at the distal segment or the left hand has three sound fingers and both palms are intact, a driver's license for small cars, small automatic transmission cars, low-speed trucks, or three-wheeled cars can be applied for. (Note: The upper limb requirements are also an important part of the latest reforms.) Torso and neck: No motor dysfunction is allowed. The following physical conditions disqualify an applicant from obtaining a driver's license: Having used or injected drugs within the past three years, or having been released from compulsory isolation detoxification for less than three years, or being addicted to long-term use of dependent psychotropic drugs and not yet having quit. Having organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, Parkinson's disease, mental illness, dementia, or other neurological diseases that affect limb movement and hinder safe driving.

Is the car okay if it didn't stall while wading through water?

Stalling or not is not an absolute indicator. It is recommended to conduct an inspection. If the car didn't stall, it indicates the water wading wasn't too severe. Check the air filter, fuel filter, and battery for any signs of water ingress or moisture. Replace them promptly if necessary. Also, inspect whether the transmission has taken in water. If so, replace all the lubricating oil. Additional information: 1. Do not restart immediately if the car stalls unexpectedly: If the car stalls unexpectedly in water, do not attempt to restart it immediately. Instead, take measures to tow the car to a safe location with less water as soon as possible. Water entering the engine is a very serious issue. Water can enter through the air filter into the intake valve and then into the cylinder block via the intake pipe. Under no circumstances should you try to restart the engine at this point. 2. Remove brake pad moisture promptly: After wading through water, it is essential to remove moisture from the brake pads promptly, especially for vehicles with drum brake systems. Failure to do so may result in loss of braking power after wading, leading to severe hazards or accidents.
