In general, the most likely reason for a new car's air conditioning not cooling is the lack of refrigerant in the vehicle. It could also be due to insufficient power supply voltage. Below is a detailed explanation of the reasons for a new car's air conditioning not cooling: 1. Insufficient refrigerant: Refrigerant, also known as coolant or freon, is the medium substance used in various thermal machines to complete energy conversion. It can absorb heat from the cooled object at low temperatures and then transfer it to cooling water or air at higher temperatures. A lack of refrigerant in the vehicle will cause the car's air conditioning not to cool. 2. Insufficient power supply voltage: The normal starting voltage for air conditioning is 220V ±10%. Almost all compressors can start at voltages above 200V. At voltages above 180V, 70-80% can start. At voltages above 160V, only a few machines can start. Insufficient power supply voltage will cause the car's air conditioning not to cool.

Can I Replace Just One Car Shock Absorber?

It is not advisable to replace just one shock absorber; it's best to replace them in pairs on the same axle. If only one is replaced, the lifespan of the other will be shortened, and it may fail soon. More information about the car shock absorber system is as follows: 1. The shock absorber system consists of two parts: the shock absorber and the spring. Shock absorbers typically need to be replaced after about 100,000 kilometers. Even if the shock absorber is not broken or leaking oil, its damping effectiveness will be significantly reduced. 2. As long as the car is moving, the shock absorber is constantly working. Unlike other car parts, shock absorbers can last for a long time.

What Causes Engine Oil Leaks?

Engine oil leaks can be caused by the following reasons: 1. Damaged or displaced sealing gaskets; 2. Improper installation of sealing components not following specified procedures; 3. Overfilling of lubricating oil or using incorrect oil type; 4. Prolonged engine use leading to aging and failure of sealing components; 5. Excessive pressure difference between engine interior and exterior. Solutions include: 1. Tightening various fastening nuts as required and according to specifications; 2. Timely replacement of failed sealing components; 3. Proper oil maintenance to prevent sludge buildup that may clog internal check valves or breather valves; 4. Ensuring proper sealing of external connecting pipes. Frequent disassembly may cause fastening rings to loosen/break or rubber parts to stretch, reducing sealing effectiveness and leading to oil seepage.
