Why Does One Car Fan Spin While the Other Doesn't?

The reasons why one car fan spins while the other doesn't are: 1. The water temperature has not reached the required level; 2. A relay malfunction; 3. An issue with the temperature control switch. The car radiator is mainly used for engine cooling and coolant heat dissipation, ensuring the engine does not overheat and fail. It consists of fan blades, a car fan belt, and an electric motor. The maintenance methods for a car radiator are: 1. Avoid contact with acidic, alkaline, or corrosive substances; 2. Use soft water to reduce scale formation; 3. Choose a non-corrosive antifreeze; 4. During radiator installation, avoid damaging the cooling fins or denting the radiator to ensure cooling efficiency and sealing.

What are the differences between 1.6L and 2.0L engine displacements?

1.6L and 2.0L engine displacements differ in the following aspects: 1. Difference one: Power output - The 2.0L engine delivers stronger power than the 1.6L engine. 2. Difference two: Fuel consumption - The 2.0L engine consumes more fuel compared to the 1.6L engine. Here's a brief introduction about automobile engine displacement: 1. Automobile displacement refers to cylinder volume: It's the sum of the piston's displacement from top dead center to bottom dead center in the cylinder, plus the combustion chamber volume. 2. Importance of engine displacement: Engine displacement is one of the most crucial structural parameters, representing engine size more accurately than cylinder bore and number. Many engine performance indicators are closely related to displacement.

What is the reason for engine shaking at startup but no shaking while running?

The reasons for engine shaking at startup but no shaking while running are: 1. The spark plug is damaged, the gap between the spark plug electrodes is worn out, resulting in insufficient spark plug ignition and incomplete combustion of the air-fuel mixture; 2. Poor quality gasoline leads to poor atomization effect of the fuel injector, causing incomplete combustion of the air-fuel mixture in the cylinder; 3. The throttle is dirty or the fuel injector has excessive carbon deposits; 4. The fuel pump supply pressure is abnormal or the intake pressure sensor has incorrect values and poor performance. The function of the engine is to convert thermal energy into mechanical energy by expanding gas after combustion in a sealed cylinder, pushing the piston to do work, thereby providing power for the vehicle. The maintenance methods for the engine are: 1. Clean the air filter; 2. Remove sludge from the throttle; 3. Clean carbon deposits from the fuel injector.

What are the hazards of retrofitting laser headlights?

If not approved by the traffic management department in advance, retrofitting laser headlights is illegal and cannot pass the annual inspection normally. Here is more information about laser headlights: 1. Development History: Automotive headlights have evolved from halogen lamps to xenon lamps and then to LED lamps, with increasing brightness and longer illumination distances. However, car manufacturers are not satisfied with these. A new type of headlight with even higher brightness and longer illumination distance has emerged—the laser headlight. 2. Advantages of Laser Headlights: Laser headlights can illuminate an area approximately 600 meters ahead of the car, while LED headlights can only reach about 300 meters. This performance ensures good lighting conditions for drivers even in very remote areas, enhancing driving safety. Laser headlights represent the future trend of headlights. Currently, Audi and BMW have publicly demonstrated the performance of laser headlights. The biggest challenge for laser headlights now is their high cost, making them unsuitable for widespread adoption.

How many liters of transmission oil does the Octavia need?

The Skoda Octavia generally requires two liters of transmission oil. It is recommended to replace the automatic transmission oil and oil filter every 60,000 kilometers. For vehicles equipped with a transmission oil filter, the filter should also be replaced during the oil change. Transmission oil is a lubricant that keeps the gear system clean, extends the lifespan of the transmission components, and provides effective lubrication even in low-temperature conditions. It also reduces oil loss under harsh operating conditions. Below is an introduction to transmission oil: 1. Depending on the transmission structure, transmission oil is divided into automatic transmission oil and manual transmission oil. 2. Automatic transmission oil: Abbreviated as ATF (Automatic-Transmission-Fluid), it is specifically designed for automatic transmissions. Early automatic transmissions did not have dedicated oil and instead used engine oil. Due to significant differences in operating conditions and technical requirements, the use of engine oil as automatic transmission oil was quickly phased out. Today's dedicated automatic transmission oil serves as the hydraulic fluid for the torque converter, the lubricant for the planetary gear structure, and the hydraulic oil for the shifting mechanism. Under normal driving conditions, automatic transmission oil should be replaced every 120,000 kilometers, and under severe driving conditions, every 60,000 kilometers. 3. Manual transmission oil: Commonly referred to as gear oil, it is classified into five grades (GL-1 to GL-5) by the American Petroleum Institute based on quality levels. GL-1 to GL-3 have lower performance requirements and are used for lubricating spur and bevel gears, as well as gears in transmissions and steering systems under general loads. GL-4 is used for high-speed, low-torque and low-speed, high-torque conditions, such as the lubrication of hypoid gear drive shafts and manual transmissions. GL-5 has the highest performance level and is used for hypoid gear drive shafts and manual transmissions under severe operating conditions with high impact loads. Under normal driving conditions, manual transmission gear oil should be replaced every two years or 60,000 kilometers.
