Antifreeze comes in four colors: red, blue, green, and yellow. Different colors should not be mixed randomly, and it should never be mixed with other maintenance fluids like windshield washer fluid. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine block or cylinder head due to expansion. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Engines and their cooling systems are made of metals such as copper, iron, aluminum, steel, and solder. These metals, when exposed to high temperatures and water over time, can corrode and rust. Antifreeze not only avoids causing corrosion to the engine cooling system but also provides anti-corrosion and rust-removal functions.

Why does the coolant level decrease?

Engine coolant reduction can be attributed to the following reasons: 1. Leakage in the engine cooling system, causing the coolant to drain completely: In this case, you need to inspect the entire cooling circulation system from the radiator to the coolant circulation pump, engine inlet and outlet, coolant pipes, and heat dissipation unit for any leakage points. 2. Thermal expansion and contraction: When the engine is cold, the coolant level may be below the minimum line, but after the engine runs for a while, it returns to the middle of the F/L range. It is recommended to check the coolant level before starting the engine. 3. Air pockets in the cooling system: After some time of circulation, the trapped air is expelled, leading to a drop in the coolant level.

Which traffic lights don't have cameras?

Many traffic lights at non-busy intersections don't have cameras installed. However, whether a traffic light intersection has cameras can usually be determined visually. If there are cameras at a traffic light intersection, there are typically warning signs such as 'violation photo enforcement ahead' or similar reminders. If there are no cameras, there won't be such warnings about photo enforcement ahead. Traffic violation enforcement isn't limited to just electronic eyes; it also includes 360-degree system captures, electronic checkpoints, mobile patrol car captures, and on-duty traffic police officers. Running a red light results in a 6-point deduction from the driver's license, a fine, and may significantly endanger the personal safety of both the driver and others, potentially causing severe property damage. Therefore, vehicle owners must comply with traffic regulations.

Is there a reward for reporting traffic violations?

Reporting traffic violations may result in certain rewards, with the specific amount determined by local reward standards. If the reported individual is confirmed by the traffic police department to have committed illegal acts, the reporter may receive a certain monetary reward. The rewards vary depending on the location and the type of violation. You can report violations through the phone number provided by the traffic management app 12123. Follow the instructions given by the customer service personnel, clearly describe the illegal act, submit relevant evidence, and provide the license plate number of the offending vehicle. After the traffic police department accepts, investigates, and confirms the report, if the violation is verified, the reporter can receive the corresponding reward.

Are holiday traffic violations extended?

Holiday traffic violations are not necessarily extended. The recording of violations follows these scenarios: 1. For simplified penalty decisions issued on-site by traffic officers, according to internal case-handling regulations, they must be entered into the system within 24 hours; 2. For violation notices and compulsory measure certificates issued on-site by officers, per internal regulations, they must be entered into the system within 48 hours, with seized items transferred to the county-level or higher traffic management department; 3. For violations captured via non-contact enforcement or electronic monitoring, internal regulations require entry into the system within 7 working days. Delays may occur in all three scenarios as they are internal workflow standards binding only to officers. Violations of case-handling procedures may lead to disciplinary actions against officers but do not affect the determination of the violation facts.

What to Do If You Put the Wrong Fuel in Your Car?

Here are the solutions for adding the wrong fuel: 1. High-grade car filled with low-grade fuel: If a high-grade gasoline car is filled with low-grade gasoline, it is recommended that the owner drain the wrong fuel or purchase relevant fuel additives to improve fuel quality and reduce the damage of low-grade fuel to the engine. 2. Low-grade car filled with high-grade fuel: If a low-grade gasoline car is filled with high-grade gasoline, there is no problem, just remember not to make the same mistake next time when refueling. 3. Diesel and gasoline mixed: If a gasoline car is filled with diesel or a diesel car is filled with gasoline, contact a car repair shop as soon as possible to clean the fuel tank and fuel system, and conduct a comprehensive inspection of the engine.
