The reasons why the thermostat of Geely Vision does not open after replacing the coolant are as follows: Internal damage to the thermostat: The thermostat automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will seriously affect the normal operation of the engine. Damage to the thermostat opening valve: If the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine warm-up time, resulting in the engine temperature being too low. Air not completely purged: If the air is not completely purged after replacing the coolant in the Geely Vision, it will cause the thermostat not to open.

Why has the Sagitar's fuel consumption suddenly increased?

The reasons for the increase in Sagitar's fuel consumption can be varied, possibly due to engine malfunctions; prolonged lack of maintenance leading to aging car parts, which can cause a sudden rise in fuel consumption; higher viscosity of engine oil; driving habits, etc. Below is more related information: 1. Lower temperatures: Generally, during the use of the car, fuel consumption tends to increase in lower temperature environments. This is because the engine needs to maintain a constant temperature to function properly, and in colder conditions, the engine dissipates more heat, requiring more fuel to maintain its operating temperature, thus increasing fuel consumption. 2. Lack of regular maintenance: If the car is not regularly maintained, dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts. If the air filter is too dirty, the engine requires more energy to intake air during operation. Additionally, insufficient air intake can lead to incomplete combustion of fuel in the engine, thereby increasing fuel consumption. 3. Spark plugs: Not replacing spark plugs for a long time can also cause an increase in fuel consumption. When the spark plugs are not functioning properly, insufficient ignition energy can lead to delayed ignition, missing the optimal ignition time, resulting in incomplete combustion of fuel and wasting part of the fuel.

Reasons for Changes in Vehicle Technical Condition

The reasons for changes in vehicle technical condition lie in the alterations of technical states of automotive components, mechanisms, or assemblies, which constitute the fundamental causes of automotive technical variations. Factors such as natural wear, plastic deformation, fatigue damage, corrosion, and other changes in parts or materials directly affect the modification of vehicle technical conditions. Supplementary information: Vehicle Technical Condition: 1. Vehicle technical condition refers to the comprehensive summation of a vehicle's appearance and performance parameter values at a specific moment, which characterizes its operational capability. The evaluation of vehicle technical condition is generally conducted through comprehensive assessment of automotive performance indicators, completeness of vehicle equipment, and external integrity status, typically measurable quantitatively. Automotive performance indicators include: power performance, fuel economy, braking performance, handling stability, and ride comfort. 2. The vehicle technical condition determines operational efficiency, safety, and environmental impact. 3. As mileage (or usage time) increases, the vehicle technical condition gradually deteriorates, leading to declines in power performance, fuel economy, reliability, and safety, along with increased environmental hazards. Primary indicators of deteriorating technical condition include reduced maximum speed, prolonged acceleration time, delayed braking response, heavy steering, vehicle vibration with abnormal noises, increased fuel/lubricant consumption, and abnormal exhaust emissions with peculiar odors.

How many points are deducted and how much is the fine for driving in the wrong direction on provincial roads?

Driving in the wrong direction on provincial roads will result in a fine and a deduction of 3 points. The penalty for driving in the wrong direction depends on the following two situations: 1. Situation one: In urban areas and other roads, 3 points will be deducted, and a fine will be imposed. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Order No. 123 of the Ministry of Public Security), motor vehicle drivers who commit any of the following violations will have 3 points deducted: driving a motor vehicle without overtaking, yielding, or driving in the wrong direction as required. 2. Situation two: On highways, 12 points will be deducted, a fine will be imposed, and the driver's license may be suspended for twelve months. The following are several situations of driving in the wrong direction: 1. Situation one: On roads with solid dividing lines, motor vehicles entering the opposite lane, where the road dividing line is a double solid line or a single solid line, are not allowed to cross the line under any circumstances. 2. Situation two: On roads with dashed dividing lines, it is possible to borrow the lane to overtake safely, but once an accident occurs, the vehicle borrowing the lane will be considered to be driving in the wrong direction. 3. Situation three: On roads with one-way signs, any motor vehicle entering will be considered to be driving in the wrong direction.

What should be noted when following the preceding vehicle for a right turn while driving?

When following the preceding vehicle for a right turn while driving, three key points should be noted: First, the distance to the preceding vehicle. When driving behind another vehicle, the preceding vehicle may encounter various situations due to road conditions. Common scenarios include stopping to yield to pedestrians or other vehicles, or slowing down. Therefore, during a right turn, it is crucial to maintain a sufficient distance from the vehicle ahead to prevent accidents. Second, pedestrians at crosswalks. During a right turn, it is essential to stay focused, especially at signal-controlled intersections. Continuously observe the situation on the pedestrian crossing, reduce speed, and be prepared for sudden pedestrian movements. These pedestrians may be crossing legally with a green light or illegally against a red light. Third, blind spots on the right side. Right turns can create visual blind spots on the right. Drivers must consistently check the right-side mirror to avoid these blind spots. If necessary, slightly lean to the right to improve mirror visibility and stay alert for sudden appearances of non-motorized vehicles, pedestrians, or small animals. Daily driving requires strict adherence to traffic rules, with extra caution during right turns. Typically, vehicles follow the preceding vehicle for a right turn, making it a high-risk scenario for traffic accidents. Drivers must remain highly vigilant in such situations.

Should You Accelerate and Honk When Driving Uphill in a Motor Vehicle?

No, honking is correct, but accelerating is the wrong behavior. Here is some information about parking on an uphill slope: 1. Gear Function: It utilizes the engine's resistance to help the vehicle better perform parking braking. Since first gear and reverse gear are the two gears with the largest transmission ratios in the car's transmission, and also the two gears with the smallest transmission ratios when the power is reversed, using first gear and reverse gear for engine parking braking provides the greatest braking force and the best braking effect. 2. Gear Shifting Technique: Remember the principle of "accelerate before upshifting, decelerate before downshifting" when changing gears. Before upshifting, "rev" the throttle to increase the speed first, and before downshifting, "release" the throttle to reduce the speed first.
