What Are the Causes of Car Air Conditioning Not Cooling?

Car air conditioning not cooling can be caused by insufficient refrigerant, dirty condenser, damaged air conditioning compressor, throttle valve or expansion valve, aging or loose belt, or water in the pipeline. Here are specific methods to diagnose the causes of car air conditioning not cooling: 1. Insufficient refrigerant. Refrigerant loss is mainly due to leakage. If the car's air conditioning performance deteriorates after adding refrigerant for a period of time, it indicates a condenser leak, and the condenser needs to be replaced. Adding fluorescent dye to the refrigerant and inspecting with special glasses can reveal the leak point. In severe cases, oil stains can be observed on the condenser surface through the grille, indicating a leak. 2. Dirty condenser. If the air conditioning performance is poor in summer, but the system checks show no issues and the high and low pressures are normal, cleaning the radiator and condenser is necessary. Pollen or debris clogging the condenser can cause engine overheating or poor air conditioning performance. 3. Damaged air conditioning compressor, throttle valve, or expansion valve. The probability of compressor failure is relatively low. 4. Aging belt. An aging belt may slip during operation, leading to belt breakage, noise, loss of power assistance, or poor air conditioning performance. 5. Water in the pipeline. The car air conditioning system includes a dryer tank, which absorbs moisture from the refrigerant to prevent excessive moisture from reducing cooling capacity. When the desiccant in the dryer tank is saturated, moisture can no longer be filtered out. When the refrigerant passes through the expansion valve orifice, its pressure and temperature drop, causing freezing. This obstructs refrigerant flow, increases resistance, or completely blocks circulation, resulting in the air conditioning not cooling.

Min K - Fujian Provincial System, Pingtan Comprehensive Experimental Zone, Fujian Province. Additional information: The first character of a license plate number is a Chinese character, representing the abbreviation of the province where the vehicle is registered. The second character is an English letter representing the prefecture-level administrative region where the vehicle is registered. Typically, 'A' represents the provincial capital city, 'B' represents the second-largest city in the province, and so on.

What are the drawbacks of replacing 185 tires with 195 tires?

The drawbacks of replacing 185 tires with 195 tires include increased fuel consumption, higher risk of rollover, and abnormal operation of the vehicle system. Below are the detailed explanations: Increased fuel consumption: The increased rolling resistance makes the steering wheel heavier during driving, leading to higher tire noise and fuel consumption. Higher risk of rollover: It interferes with the geometric dimensions designed for the body and suspension, significantly increasing the turning radius. This makes the vehicle more prone to rollover, especially during sharp turns, as the centrifugal force from the car's tilt can lift the inner wheels off the ground. Abnormal operation of the vehicle system: It can alter driving data, causing abnormalities in the vehicle system. For example, ABS, ESP, mileage, and fuel consumption are calculated based on the original tire's outer diameter. Replacing the tires without the system being able to make correct judgments can affect driving performance.

Can 0w40 engine oil be used in summer?

0w40 is an all-season engine oil and can be used in summer. For 0W40 engine oil, the number after W is 40, which refers to the viscosity of the oil at 100°C, indicating that 0W40 oil has higher viscosity at high temperatures, providing better protection and making it suitable for summer use. Here are the methods to determine the suitable season for engine oil: 1. W stands for winter. The number before W represents the oil's fluidity at low temperatures. The smaller the number, the greater the fluidity of the oil. 2. The number after W refers to the viscosity index at high temperatures. The larger the number, the higher the viscosity of the oil, indicating better protective performance of the oil.

What to Do When Your Driver's License Exceeds the Six-Year Validity Period?

After your driver's license exceeds the six-year validity period, you need to check the expiration time. The relevant information is as follows: 1. If it has been expired for less than one year, you can still renew it without a fine. If it has been expired for more than one year, the vehicle management office will revoke your driver's license. 2. If your revoked driver's license has not exceeded two years, you can take the Subject 1 test at the vehicle management office. Passing the test will restore your driving qualification, and then you can renew your license. If your revoked driver's license has exceeded two years, you will have to retake all the tests. Below are the relevant materials for license renewal: 1. Materials required for renewal application: (1) "Motor Vehicle Driver's License Application Form". (2) Identity proof of the motor vehicle driver. (3) Motor vehicle driver's license. (4) A medical certificate issued by a county-level or above medical institution or a military regiment-level medical institution. (5) The motor vehicle driver can authorize an agent to handle renewal, replacement, submission of medical certificates, extension, and cancellation procedures. (6) Three recent one-inch bareheaded, white-background color photos. 2. Vehicle management office procedures: (1) Undergo a physical examination at a county-level or military regiment-level medical institution. (2) Take a number at the vehicle management office, traffic police branch, or district (city) traffic police team and submit the materials at the acceptance window. (3) Pay the relevant fees at the payment window. (4) Collect the driver's license at the license and certificate window. 3. Processing time: If all requirements are met and the procedures are complete, it will be processed on the spot. 4. Processing unit: The vehicle management office of the traffic management department of the public security authority where the motor vehicle driver's license was issued.

How to Test the Condition of a Car Battery?

Here are several methods to test the condition of a car battery: 1. Perform a starting test on the car or electric vehicle: Use the car key to start the engine. If the key fails to start the car after insertion, and the vehicle has not been left unused or discharged for an extended period, it can be preliminarily judged that the battery is severely aged and needs replacement. 2. Conduct a discharge test on the car: After driving the car normally for a while, if it will not be used for some time, turn the key to the circuit-on position and then turn on the headlights. If the headlights go out within a day or two, it can be determined that the battery is aging. 3. Observe the sound level of in-car electronic devices like the radio during the starting process: If the sound fluctuates between loud and soft, it indicates unstable battery output. 4. Check for white crystalline deposits on the two electrodes of the battery: If there are many deposits, it indicates severe battery sulfation, and replacement is needed. 5. Check the production date and specifications on the battery cover: If the production date is ten years or older, replacement is recommended. 6. Test the battery voltage under no-load conditions: Use a multimeter to measure the battery voltage under no-load conditions. The voltage should be 12V and very stable. If the voltage is too low or fluctuates, it indicates battery aging. 7. Monitor the voltage indicator: Connect the multimeter to the battery's positive and negative terminals, start the car, and turn on the air conditioning. If the voltage drops significantly, it indicates battery aging.
