Running out of car coolant will affect the heat dissipation effect of the radiator, failing to achieve the required cooling function. Without proper coolant circulation, it can lead to high temperatures, and in severe cases, cause engine burn damage. In cold climates, it can also result in the engine or radiator freezing, leading to engine failure and rendering the vehicle unusable. Methods to determine if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to low coolant, although it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Check the water level scale markings on the coolant reservoir. The normal coolant level should be between the maximum and minimum marks. To determine if coolant is low, check the scale. If the coolant is below the minimum mark, it indicates a shortage of coolant.

Do You Need to Press the Brake When Shifting to S Gear?

You do not need to press the brake when shifting to S gear. The speed in S gear is below 90 km/h. Below are the main scenarios for using S gear: 1. Overtaking. When in a hurry to overtake, if you feel that the acceleration (speed) in S gear is too slow and does not reach the desired speed, you can directly shift into S gear without pressing the brake. At this time, the engine speed increases, and the vehicle speed will significantly improve. After overtaking, shift back to D gear directly, also without pressing the brake. If you already have considerable speed in D gear during overtaking, simply increasing the throttle is sufficient to overtake, and using S gear is not recommended. Shifting back to S gear at excessively high speeds may damage the gears. 2. Steep slopes and uphill/downhill driving. For starting on very steep slopes or prolonged uphill driving, it is recommended to use S gear. S gear provides greater torque, allowing for smooth starts with just a slight increase in throttle. For prolonged uphill driving, especially on steeper slopes, S gear is more suitable. However, it is important to note: on long slopes, you should not aim for high speed; a slight increase in throttle is sufficient, otherwise, it will consume more fuel and easily raise the engine temperature. If D gear feels insufficient when going uphill, you can directly shift into S gear without pressing the brake. For long downhill driving, if the slope is too steep, it is recommended to use S gear. However, if you were previously using D gear for downhill driving, switching to S gear requires pressing the brake depending on the speed to slow down before switching.

For how many years can a vehicle not be insured under auto damage insurance?

Generally, private vehicles over 8 years old are not covered by auto damage insurance, and very few insurance companies will insure vehicles over 10 years old. Overview of auto damage insurance: Auto damage insurance refers to a type of commercial vehicle insurance where the insurer compensates within reasonable limits for damages to the insured vehicle caused by an insured accident while the vehicle is being driven by the policyholder or an authorized driver. Coverage of auto damage insurance: Vehicle damage insurance typically covers losses to the insured vehicle caused by natural disasters such as lightning, storms, heavy rain, floods, etc., as well as accidents like collisions and overturns, along with related rescue expenses.

What is the Scrap Life of Diesel Private Cars?

Diesel private cars are not scrapped based on age, but rather on mileage and emission measurement data as the standard. If a diesel private car reaches 600,000 kilometers in mileage, it will be guided to scrap, and if it fails to meet environmental standards, it will be forcibly scrapped. The elimination and scrapping of old vehicles now follow new regulations, which abolish the working life limit for private cars and guide scrapping at 600,000 kilometers of driving distance. Small and mini non-operating passenger cars, large non-operating cars, and wheeled special machinery vehicles have no working life limit. Private cars need to undergo two annual inspections per year starting from the 15th year after registration, and those over 20 years old must undergo four regular inspections per year starting from the second year. Strict limits are imposed on older vehicles during annual inspections, and private cars are subject to power testing methods.

Do Diesel Vehicles Need to Add Diesel Additives?

Diesel vehicles do not need to add diesel additives. Introduction to Diesel Engines: Diesel locomotives, also known as internal combustion locomotives, refer to railway locomotives that use diesel engines as the power source and drive the wheels through transmission devices. Internal combustion engines are stable, less prone to failure, fast, quick to start, have strong pulling power, high efficiency, and a commanding sound. The working cycle of a diesel engine has many similarities with that of a gasoline engine, but the ignition method differs. In a diesel engine, the mixture in the cylinder is ignited by compression rather than by a spark. Working Principle of Diesel Engines: The working principle of a diesel engine involves generating kinetic energy by burning diesel in the cylinder, which drives the crank-connecting rod mechanism connected to the piston, performing reciprocating circular motion around the crankshaft to output power. A four-stroke diesel engine consists of four strokes: intake, compression, power, and exhaust. Differences Between Diesel and Gasoline Engines: Unlike gasoline engines that ignite a fuel-air mixture, diesel engines do not require spark plugs. Fuel is directly injected into the cylinder, where it mixes with air, is compressed, heated, and ignited by the high temperature generated from compression to complete the power stroke. In contrast, gasoline engines send a mixture of gasoline and air into the cylinder and rely on spark plugs to ignite it for the power stroke. Additionally, diesel engines have a higher compression ratio (above 20) compared to gasoline engines, resulting in greater burst pressure during operation, which translates to better power performance and higher torque. Specifically, this means better load-carrying and hill-climbing capabilities.

How many subjects are there in the C1 instructor license exam?

C1 instructor license exam is divided into three subjects: theoretical exam (Subject 1), field driving operation exam (Subject 2), and demonstration teaching method exam (Subject 3). Scoring and passing criteria: Each of the three subjects (theoretical, field driving operation, and demonstration teaching method) has a full score of 100 points. A score of 80 points or above (including 80 points) is considered passing. All required subjects must be passed to qualify for the corresponding vocational qualification exam. The C1 driver's license is a type of driver's license code, permitting the driving of small and micro passenger vehicles, light and micro cargo vehicles, and light, small, and micro special operation vehicles.

What is the difference between self-scheduling and system-arranged scheduling for Subject 1?

There are the following differences between self-scheduling and system-arranged scheduling for Subject 1: 1. Success rate: System-arranged scheduling has a higher success rate, which means that when there are many applicants, [system-arranged scheduling] will allow you to pass the exam faster than [self-selecting exam sessions]. However, if there are not many applicants, self-selecting exam sessions allows you to choose the earliest exam time and session. 2. Autonomy: The advantage of system-arranged scheduling is the higher success rate, but you cannot choose the exam time or session, as they are randomly assigned by the system. The benefit of self-selecting exam sessions is that you can choose both the exam time and session yourself.
