Toyota diesel D4D uses 5W-30 or 0W-30. Relevant information is as follows: 1. Lubrication: When the engine is running, the friction between components is rapid and intense. A sufficiently thick oil film is required between the piston and the cylinder to separate the two components, thereby reducing friction. 2. Cooling: The engine generates a large amount of heat during operation, and the oil carries some of the heat back to the oil pan to dissipate. 3. Cleaning: Oil sludge, carbon deposits, worn metal particles, and inhaled dust can form on engine parts, which can easily lead to carbon buildup.

What is the range of the Song Pro-EV in kilometers?

The range reaches 502km, supporting 70kW ultra-fast charging. Power system: The Song Pro-EV high-power long-range version adopts BYD's third-generation high-power permanent magnet synchronous motor. At the same time, the motor uses a highly integrated design with a maximum efficiency of up to 97%, matched with a fixed gear ratio transmission. Battery: It uses a high-efficiency ternary lithium battery. Through lightweight module design, the energy density of the power battery pack is increased, which also significantly improves the vehicle's range. It is reported that the NEDC range of the Song Pro-EV high-power long-range version reaches 502km. Another highlight is that the ternary lithium battery pack adopts BYD's new intelligent temperature control system, which allows the battery to operate in a comfortable zone under various environmental conditions, thereby enhancing the performance, lifespan, and safety of the battery cells throughout their entire lifecycle.

At what temperature does the Passat B5 fan operate?

It operates around 90 degrees and starts at 95 degrees. Working principle of Passat electronic fan: The car's electric fan is controlled by a thermostat. When the water temperature rises to the upper limit, the thermostat turns on the power, and the fan starts working. When the water temperature drops to the lower limit, the thermostat turns off the power, and the fan stops working. Methods to determine if the electric fan is good or bad: Check the color of the coil at the fan motor's ventilation port for any signs of burning. If there are burn marks, it means the fan motor coil can no longer be used. Turn the shaft by hand to observe its operation. If it operates with difficulty or is not smooth, it indicates that the internal bearings are lacking oil or the rotor is scraping. If scraping occurs, in addition to adding oil and cleaning, the bearings on both sides must be replaced to eliminate the scraping phenomenon.

How many liters of engine oil should be added to the Captiva?

The Captiva requires approximately 4.5 liters of engine oil. Engine oil is composed of base oil and additives. Base oils are categorized by quality into Group I, Group II, and Group III base oils, with Group I and II being mineral oils, and Group III being synthetic base oils. There are many types of additives, and the quantity and quality of additives directly affect the API quality grade of the lubricating oil. The functions of engine oil are: 1. To reduce friction and high temperatures; 2. To minimize gas leakage and prevent external contaminants; 3. To protect components from contact with water, air, and acidic harmful gases; 4. To cushion the pressure rise in the engine cylinder; 5. To clean away dirt generated on the working surfaces of components.

How to reactivate ETC after removal?

To reactivate ETC after removal, follow these steps: 1. Follow the relevant ETC software; 2. Click on 'Online Activation' in the software and enter the vehicle and owner's information; 3. Activate and upload photos of the front of the vehicle; 4. Insert and remove the ETC card twice in the device to display 'Bluetooth Connection' on the screen, and it will automatically show successful activation. Notes for using ETC: 1. Maintain a distance of more than 10 meters from the vehicle in front to prevent automatic sensing and payment for the front vehicle; 2. When using a debit card to bind ETC, insufficient balance will also cause payment failure; 3. The ETC lane recognizes a speed of 20 km/h, and if the speed is too fast, it may fail to read the vehicle device information, leading to payment failure.
