Control the vehicle speed properly, while also reducing the car's load, maintaining normal tire pressure, minimizing brake usage, using air conditioning less frequently, avoiding unnecessary throttle presses and sudden braking, and maintaining appropriate gear positions. Keeping a reasonable gear position means shifting gears promptly when the speed increases or the RPM reaches the required level. Here are some related details: 1. How to check car fuel consumption: Most onboard computers display the average fuel consumption value on the dashboard, but it often differs slightly from the actual fuel consumption. 2. Fuel consumption refers to the fuel economy indicator of a car driving at a constant speed on good road conditions. Since constant-speed driving is a fundamental operating condition for vehicles on highways, and this type of fuel consumption is easy to measure, it is widely adopted.

How to Identify Air in Brake Fluid?

Methods to identify air in brake fluid: 1. Start the vehicle and press the brake pedal firmly. If the pedal sinks all the way to the floor, this indicates air in the system. 2. If the pedal feels normal after a few pumps but sinks again after releasing the pedal for a few minutes and then pressing it, this also suggests air in the brake system lines. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, or other transportation tools or machinery. Brake fluid, generally referring to hydraulic brake fluid, is the liquid medium that transmits braking pressure in hydraulic braking systems and is used in vehicles equipped with hydraulic braking systems. There are three types of brake fluid: castor oil-based, synthetic, and mineral oil-based.

Should the old driver's license be destroyed?

When replacing a driver's license, the old one will be destroyed on-site by the staff. Relevant information: 1. Introduction: The full name of the driver's license is the motor vehicle driver's license, also known as the "driving license," which is the certificate required by law for motor vehicle drivers. 2. Expansion: Driving a motor vehicle requires certain driving skills. People lacking such skills may cause traffic accidents if they drive randomly. Generally, individuals cannot drive on the road without a license. However, for those who already possess safe driving skills, the document that permits them to drive vehicles on the road is the "driver's license." This indicates that a driver's license is a type of "permit."

Is It Normal for the Expansion Tank to Have No Water?

It is not normal for the expansion tank to have no water. If the pipes connecting the main radiator and the expansion tank, as well as the radiator cap, are functioning properly, the main radiator will draw water from the expansion tank when it runs low. The expansion tank should maintain about half of its coolant capacity—having no water at all is unacceptable. Common reasons for frequent coolant loss in the expansion tank include: 1. A damaged cylinder head gasket; 2. Leaking hoses; 3. Radiator leaks or faulty valves; 4. Heater core leaks; 5. Leaking core plugs. The expansion tank is a critical part of the engine cooling system, helping to balance radiator pressure. When the engine temperature rises, the coolant expands, and some antifreeze flows into the expansion tank through the radiator cap. Conversely, when the temperature drops and the cooling system pressure becomes negative, the system draws antifreeze back from the expansion tank into the cooling system via the radiator cap.
