Which car models use purple coolant?

Models like BYD use purple coolant. Coolant generally comes in different colors such as purple, green, and blue, depending on the specific car model. How to choose coolant: The basic indicators of coolant are freezing point and boiling point. On the market, coolant freezing points include specifications like -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. Coolant replacement cycle: For vehicles that run for long periods, such as taxis, high-quality coolant should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the coolant, it should be replaced promptly, and the system should be cleaned.

What does it mean to start the engine without shifting to neutral?

Starting the engine without shifting to neutral means starting the car by depressing the clutch, which is essentially coasting in neutral. Introduction to Shifting to Neutral: Shifting to neutral refers to moving the gear from any of the 1st to 5th gears into neutral while the car is moving or before turning off the engine after parking. This applies to manual transmission cars. For automatic transmission cars, this concept doesn't exist because although they also have a neutral gear (N), it is not allowed to shift into N while the car is in motion, as it can cause significant damage to the transmission or even render it useless. Introduction to Coasting in Neutral: The term 'coasting in neutral' is somewhat outdated now. For carburetor-equipped cars, shifting to neutral and coasting at any speed did save fuel, but the trade-off was that without the engine's braking effect via the clutch, the entire burden of deceleration fell on the braking system of all four wheels. If an emergency brake is needed while coasting in neutral, the braking distance would be longer compared to coasting with the gear engaged. In other words, while saving fuel, it also introduced some risks in terms of braking performance.

How to Use a Car Air Conditioner?

To use a car air conditioner, follow these steps: Start the engine and wait until it runs smoothly. First, turn on the fan, then press the AC button to activate the cooling function. Next, adjust the temperature knob to a comfortable level and set the direction of the air vents. For automatic air conditioners, simply press the AUTO button and adjust the air vent direction as needed. The car air conditioner is an air conditioning device installed in vehicles, capable of cooling, heating, ventilating, and purifying the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety.

What Causes Condensation Inside the Car in Summer?

Condensation inside the car in summer is caused by temperature differences. Temperature difference leads to dew formation: When the humidity in the air is constant, if the temperature of the car window is lower than the dew point, dew will form on the surface of the window. This is the fogging phenomenon often seen on the windshield. Temperature difference leads to fog formation: When there is a certain temperature difference between the two sides of the window, and the saturated vapor pressure of the water on the cooler surface is lower than the vapor pressure of the surrounding environment, water vapor will gather on the glass surface and form tiny water droplets, resulting in fog. Solution using air conditioning cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. Solution using air conditioning heating: Blow warm air onto the glass to quickly raise the temperature of the windshield and reduce the temperature difference between the inner and outer surfaces of the window, preventing excessive fogging on the windshield. The main reasons for condensation inside the car are high humidity inside the car and low temperature outside. In summer, especially when multiple people enter the car and the air conditioning is not turned on promptly, the high humidity from exhaled breath can quickly cause fogging on the windshield. At this point, you can turn on the air conditioning to blow cold air onto the windshield and use the dehumidification function to remove the fog on the windshield quickly.

What Causes the Noise When Pressing the Brake Pedal in a Sedan?

Brake noise when pressing the pedal may be due to normal ABS operation, safety reminders, loose chassis components, or unstable brake discs. The details are as follows: 1. The ABS working process is actually a cycle of locking-releasing-locking-releasing, keeping the vehicle in a critical locked state with intermittent rolling. When you press the brake pedal hard and trigger the ABS, it may produce a clicking sound, which is normal. In this case, simply press the brake pedal firmly to the floor. 2. If you hear a 'click' sound between the transmission and the gear lever when pressing the brake pedal, the main reason could be the electronic linkage between the brake system and the automatic transmission. Pressing the brake activates the transmission solenoid valve, producing the 'click' sound. This is a safety reminder, and you need to press the gear lever lock button to shift gears. 3. If you hear a clicking noise even with light braking, or if your vehicle doesn't have an automatic transmission lock button, or if the noise is continuous or frequent, you should be cautious. It is highly likely due to a brake system malfunction or loose connecting components in the chassis.

What was the last year for China 5 vehicles?

China 5 vehicles were last produced in 2019. The China 5 standard was implemented starting in 2017. Introduction to China 5 vehicles: China 5 refers to the fifth stage of national motor vehicle emission standards; the specific implementation date for China 5 was January 1, 2017. On April 1, 2016, all imported, sold, and registered motor vehicles in the Beijing-Tianjin-Hebei region and some major cities already met the China 5 emission standards. China 5 standards: The European Union began implementing similar standards in 2009, imposing stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by motor vehicles. Each upgrade from China I to China IV reduced vehicle pollution by 30% to 50%. The China 5 standard was implemented nationwide on January 1, 2017. Shortly after the implementation of China 5, the China 6 standard was quickly put on the agenda. Many regions adopted the China 6 standard ahead of schedule. For example, starting from July 1, 2019, newly registered vehicles in Guangdong had to meet the China 6 emission standards. At that time, only China 6-compliant new vehicles were available on the market, and vehicles transferred from other regions also needed to meet the China 6 standard.
