When Should the Rear Axle Oil Be Changed?

According to different oil brands, the replacement intervals vary. Below are the relevant details: 1.

What Type of Engine Oil is Best for Cars in Summer?

Car engine oils for summer use are graded as: 20, 30, 40, 50. The higher the number, the greater the viscosity, and the higher the maximum applicable temperature. Below are the relevant details: 1. The number following the SAE oil grade indicates the lowest suitable temperature. 5w-30 degrees, 10w-25 degrees, 15w-20 degrees. Therefore, by checking the grade of oil you are using and comparing it with the local winter's lowest temperature, you can determine if your oil is suitable. 2. The oil grade for summer use is SAE10W-40, meaning that if the lowest temperature does not drop below minus 25 degrees, there is no need to switch to an oil with better low-temperature resistance in winter. For summer, it's advisable to choose an oil with higher viscosity, and 10W-40 oil is very suitable for summer use.

What are the symptoms of a bad car air conditioning pump?

If the air conditioning pump is faulty, the most obvious symptom is the inability of the air conditioning system to cool. Below are the relevant details: 1. There are many reasons for abnormal noises from the air conditioning pump, such as damage to the compressor electromagnetic clutch, severe internal wear of the compressor, etc. The electromagnetic clutch is a common source of abnormal noises due to its location, making it prone to exposure to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noises occur. Additionally, a compressor drive belt that is too loose or too tight, lack of lubricating oil, or repeated engagement of the electromagnetic clutch can all cause abnormal noises. 2. Leakage in the air conditioning pump is also a common issue, with the specific leakage location being the junction between the compressor and the high and low-pressure pipes. When refrigerant leaks, compressor lubricating oil is also lost, leading to poor compression by the air conditioning pump or the air conditioning system not working. 3. Moreover, there are many reasons why the air conditioning system may not work, most of which are related to electrical circuits. A preliminary check can be done by directly supplying power to the compressor electromagnetic clutch to determine if it is faulty.
