Is Throttle Body Cleaning Necessary?

Throttle body cleaning is necessary. After prolonged use, carbon deposits will accumulate near the air flow valve plate of the throttle body. In severe cases, it can even clog the preset idle air intake opening. These issues can lead to sluggish throttle response, unstable idle speed, or even engine stalling. Therefore, the throttle body needs to be cleaned. Cleaning the throttle body every 20,000 to 40,000 kilometers is sufficient. If the driving conditions are harsh, the cleaning interval should be shortened. However, excessive cleaning can cause premature failure of the throttle body. Frequent cleaning gradually removes the special coating inside the throttle body chamber. Without this coating, the chamber becomes more prone to oil and grime buildup, creating a vicious cycle that ultimately leads to failure.

Can Antifreeze Be Mixed?

Antifreeze cannot be mixed. Although the main components of domestic antifreeze are the same, the additives used by different manufacturers vary. To distinguish between types, various colorants are added, such as light green, green, light blue, dark blue, pink, orange-red, red, etc. If mixed, different additives may undergo chemical reactions, which can have adverse effects on the radiator. Antifreeze should be added between the MAX and MIN indicator lines. Many people think antifreeze is only used in winter, but in fact, it is used year-round. Automotive antifreeze is mainly used in the cooling systems of liquid-cooled engines, offering excellent performance in preventing freezing in winter, boiling in summer, scale buildup, and corrosion.

What is the Principle of the Rearview Camera System?

The principle of the rearview camera system is based on visual measurement rearview technology. It relies on a camera at the rear of the vehicle to display road condition information behind the car on the central display screen. The driver can move the square representing the vehicle body freely on the screen via the touchscreen. If the position is appropriate, the square will change from red to green. At this point, simply engage the reverse gear and control the vehicle speed to complete automatic reversing. Limitations of the rearview camera system: 1. Ice, snow, or mud covering the camera; 2. Dark environmental lighting; 3. Extreme conditions such as sun glare or headlights from a vehicle behind; 4. Deformation or damage to the rear of the vehicle; 5. Extremely high or low temperatures and significant temperature fluctuations.

Why is water bubbling out of the car radiator?

Reasons for water bubbling out of the car radiator: 1. Engine overheating or high pressure can cause water overflow, or a damaged cylinder head gasket can also lead to water bubbling; 2. A faulty radiator cap, which contains a one-way valve, can cause water to bubble out if it's damaged; 3. Air trapped in the radiator or engine that is difficult to expel, or loose hose seals allowing air to enter, can cause coolant to be forced out of the radiator during circulation by the air pressure; 4. A cracked engine cylinder liner can allow compressed gas from the cylinder to forcibly push coolant out of the radiator during operation. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket in a continuous cycle.

Why does the car's water temperature rise slowly?

Reasons for slow rise in car water temperature: 1. The thermostat is damaged and cannot close, causing the coolant to always circulate in the large loop, which quickly lowers the engine's water temperature; 2. The cooling fan is faulty and constantly running, leading to a rapid drop in water temperature; 3. Insufficient coolant. The solution for slow water temperature rise is: Check if there are issues with the cooling system, such as: whether the shutters are blocked, whether the fan blades are deformed, or whether the water temperature sensor and circuit are short-circuited. You can remove the thermostat and place it in water at different temperatures to observe its opening condition. If it cannot open and close normally, replace the thermostat.
