What does 10w30 engine oil mean?

10w30 refers to a multi-grade viscosity all-weather engine oil. Here, 10w indicates the oil's winter low-temperature viscosity performance, while 30 represents its summer high-temperature viscosity performance. A smaller number before the 'W' means better fluidity of the lubricant at low temperatures, making it easier to start the car. A larger number after the 'W' indicates better viscosity of the oil in high-temperature environments and higher strength of the oil film formed. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties. Its functions include: 1. Lubrication and wear reduction; 2. Assisting in cooling and temperature reduction; 3. Sealing and leak prevention; 4. Rust and corrosion prevention; 5. Shock absorption and buffering.

How to Repair a Faulty Thermostat?

The methods to repair a faulty thermostat include: 1. After starting the engine, check if there is water flow in the cooling tank; 2. Inspect whether there is water flow at the radiator inlet pipe of the cooling tank; 3. Observe the water temperature gauge to see if it shows any abnormalities. The reasons for a faulty thermostat are: 1. The temperature for valve opening and full opening is too high; 2. The warm-up time is prolonged, and when the car operates at a low water temperature, the combustion gases and condensed water on the cylinder walls form acidic substances that corrode the cylinder; 3. Liquid fuel and water wash away the lubricating oil film on the cylinder walls, leading to wear on the cylinder liner and piston components; 4. Excessive temperature fluctuations between cold and hot states cause frequent contraction and expansion of the cylinder block, resulting in detachment of adhesive repairs or adhesives, which leads to diesel engine malfunctions.

Should the car air conditioner be turned on for cooling in summer?

In summer, the car air conditioner should be turned on for cooling by pressing the AC button. The working principle of the car air conditioner is as follows: the compressor compresses the refrigerant into a high-temperature and high-pressure liquid, which then becomes a medium-temperature and low-pressure liquid after dissipating heat through the air conditioner's cooling plate, and finally turns into a low-temperature and low-pressure gas after being throttled by the expansion valve. The car air conditioner, short for the car air conditioning device, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state. Its functions are: 1. To provide a comfortable riding environment for passengers and reduce travel fatigue; 2. To create good working conditions for the driver and ensure driving safety.

Should You Use Internal or External Air Circulation When Turning on the Car Heater in Winter?

Whether to use internal or external air circulation when turning on the car heater in winter depends on the specific situation: 1. When driving on urban roads, internal circulation can be used; 2. When driving on highways or long-distance routes, it is recommended to turn on external circulation; 3. Do not use external circulation when stuck in traffic. The differences between internal and external air circulation in cars are: 1. The method of air circulation is different: external circulation draws air from outside the car; internal circulation draws air from inside the car. 2. The symbols on the car air conditioning panel are different: the symbol for external circulation is from outside to inside; the indicator for internal circulation is an arrow pointing inward. 3. The functions are different: external circulation draws fresh air from outside the car to maintain air quality inside the car; internal circulation effectively prevents external dust and harmful gases from entering the car, improving the cooling and heating effects of the air conditioning.
