Why Does Antifreeze Decrease in Winter?

Winter antifreeze decrease reasons: When the engine is running, it generates extremely high temperatures, which also raise the temperature of the antifreeze. Generally, when the temperature of a liquid increases, its volume expands. If this occurs in a confined space, the pressure will rise. The antifreeze cap has a pressure relief hole that opens to release some antifreeze, maintaining an appropriate pressure level before the hole closes again. At this point, the antifreeze level will have decreased. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. Many car owners believe that antifreeze is only used in winter, but in fact, antifreeze should be used year-round.

Are Air Suspensions Prone to Damage?

Air suspension is a wear-prone component. For vehicles under normal usage, the air suspension system typically lasts about five years. However, if the driving conditions are poor, the lifespan of the air suspension can be significantly reduced. Moreover, during these five years of actual use, it's hard to guarantee that the system won't encounter issues, which further shortens its service life. Air suspension is a comfort-enhancing system in vehicles, primarily using sensors to detect vibrations and then adjusting the air suspension accordingly to achieve shock absorption. Thus, air suspension can greatly improve both driving and riding experiences. During actual driving, the vibration frequency is high. The shock absorption performance of air suspension is less ideal when the vehicle's load and vibration frequency are high, and it is also susceptible to damage from external factors.

Will There Be Major Problems If a Car Is Parked for 2 Years Without Being Driven?

There will be major problems if a car is parked for 2 years without being driven. The following are the hazards of leaving a car parked for too long: 1. Tire deformation: When a car is parked, the tires bear the entire weight of the vehicle, causing the contact area to deform over time. The longer the car is parked, the harder it is for the deformed part of the tire to recover. In minor cases, this leads to uneven rolling radius, posing safety hazards, and in severe cases, the tire may be completely ruined. 2. Oil seal aging: Prolonged parking can cause uneven stress distribution around the oil seal. Areas under greater stress will experience more deformation, leading to permanent distortion of the oil seal and oil leaks. 3. Battery failure: The car's battery discharges even when the vehicle is parked. Generally, the battery's capacity decreases by more than 1% per day due to self-discharge. Moreover, prolonged self-discharge can easily cause the battery to fail prematurely or completely. 4. Engine oil oxidation and deterioration: The longer the car remains parked, the more severe the oxidation of the engine oil becomes. Oxidized engine oil loses its lubricating properties and can corrode engine components. When starting an engine that has been parked for a long time, the cylinder and piston often experience dry or semi-dry friction, accelerating wear and tear on the parts. 5. Electronic component failure: In cars parked for extended periods, electronic components or wiring connectors are highly susceptible to moisture and corrosion. The longer the car remains parked, the higher the likelihood of malfunctions.

Does the air conditioning turn off automatically after the car is turned off?

After the car is turned off, the air conditioning will automatically shut down. The air conditioning compressor only operates when the engine is running. When the car is turned off, the compressor stops working, and the air conditioning naturally turns off. Here is some relevant information about car air conditioning: 1. Introduction: The car air conditioning system (air-conditioning-device), commonly referred to as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to an optimal state. It provides a comfortable environment for passengers, reducing travel fatigue, and creates good working conditions for the driver, playing a vital role in ensuring safe driving. It generally includes cooling, heating, and ventilation systems. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally. 2. Turning off the air conditioning: It is recommended to turn off the air conditioning one or two minutes before parking and turning off the engine. This helps dry the air vents, prevents bacterial growth inside the AC system, and protects the engine. If the air conditioning is not turned off before shutting down the engine, the next time the vehicle is started, the engine will have to bear the load of the air conditioning. The best practice is to start the vehicle and wait two to three minutes until the engine is properly lubricated before turning on the air conditioning.

What is the appropriate tire pressure in hot weather?

In hot weather, the recommended tire pressure for ordinary sedans is generally around 2.5bar to 2.7bar. However, this varies depending on the vehicle model, as different models have different tire pressure requirements. Typically, the recommended tire pressure is indicated on the car door or in the manual. During summer, it is advisable to use the lower limit of the specified standard tire pressure. If nitrogen is used for inflation, the middle value of the recommended range can be selected. Tire pressure is extremely important—it should neither be too high nor too low, as both can affect the vehicle's driving stability and safety. When driving at high speeds, if the tire pressure is too low, the tire may develop wave-like deformation, increasing the risk of a blowout. Conversely, if the tire pressure is too high, it reduces the contact area between the tire and the ground, negatively impacting the vehicle's handling.

How to Repair Wheel Rim Wear?

Methods for repairing wheel rim wear: 1. Sanding: Carefully sand the worn area of the wheel rim until it becomes smooth; 2. Filling with putty: After sanding, use metal putty to fill in the scratches on the wheel rim; 3. Continue sanding: After filling with putty, use fine sandpaper to sand any uneven areas again; 4. Painting: After the second sanding, the wheel rim can be painted; 5. Brushing: For rims with a brushed finish, professional wheel rim brushing machines are required for treatment; 6. Baking: After the primer is baked, apply a layer of clear protective coating and bake it again at high temperature; 7. Polishing: Once the paint on the wheel rim is dry, use a polishing machine to polish it for a more attractive appearance.
