What to Do If the Car Antifreeze Is Low?

If the car antifreeze is low, you can add it yourself. You need to purchase antifreeze of the same color as the original or a universal type. If the colors are different, you must completely drain the original antifreeze before adding the new one. Different colors and brands of antifreeze may have different formula components. Mixing them may cause chemical reactions between the various components, which can affect the antifreeze's performance. Method for Replacing Antifreeze: Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir, then continuously pour water into the reservoir to allow it to flow through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir will have a faint pink color. Continue adding clean water until the outflowing water is clear. Note: Do not forget to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose. This allows the antifreeze to flow quickly into the radiator. Then, add another bottle of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is purged from the system. Add more antifreeze until the reservoir reaches the "MAXT" mark.

Which Type of Rear Spoiler is Allowed for Installation in China?

Which Type of Rear Spoiler is Allowed for Installation in China?_58 Auto All types of rear spoilers are allowed for installation. After installation, it is necessary to complete the registration procedures at the vehicle management office or the traffic management department of the public security authority. Only then can the motor vehicle be legally driven on the road without any issues, and it can also undergo the normal annual inspection procedures. Reducing Lift at the Rear of the Vehicle: It can reduce the lift at the rear of the vehicle and is part of the car's aerodynamic kit. It can be installed by the owner. The spoiler can also be called a rear wing, a rear spoiler, or a deflector. Made from materials such as carbon fiber or aluminum alloy, high-end spoilers can even automatically adjust their angle, which is quite impressive. Body Kit Modifications: As long as the modifications do not exceed certain length and width limits of the vehicle body, they are permissible. For example, installing small body kits from the top trim or sport versions is allowed. However, overly exaggerated large body kits may not pass the annual inspection.

What Do Road Traffic Markings Mean?

Road traffic markings include warning signs and directional signs. Warning signs are yellow in color, serving to warn or prohibit, while directional signs are white, providing guidance. The specific explanations are as follows: Warning Signs: Double Yellow Solid Line: Mostly found in the middle of the road, it can be considered as a wall, prohibiting vehicles from crossing the double yellow line. Double Yellow Dashed Line: Mostly located in the middle of the road, particularly at intersections, used to remind drivers that they can overtake or make a U-turn along the line if road conditions permit. Double Yellow Imaginary Line: Composed of a solid line and a dashed line. Vehicles can turn from the dashed side to the solid side but not from the solid side to the dashed side. Single Yellow Solid Line: If located in the middle of the road, it primarily serves to divide lanes. If the yellow solid line is on the roadside, its main purpose is to prohibit parking along the line. Directional Signs: Left Turn, Straight, Right Turn: Informs drivers about the lane conditions. Diamond Pattern Indicator Line: Reminds drivers to slow down. Rectangular Indicator Line Near Bus Stops: Reminds drivers not to park online. Double Dotted Diamond Pattern: Alerts drivers to road conditions, allowing overtaking across the line when conditions permit.

What is the Function of an Automotive Vacuum Pump?

The function of an automotive vacuum pump is to generate negative pressure, thereby increasing braking force. For vehicles powered by diesel engines, since the engine uses compression ignition, it cannot provide the same level of vacuum pressure at the intake manifold, necessitating the installation of a vacuum pump to supply the vacuum source. The vacuum pump is primarily used for power assistance. On one side, it continuously extracts air (approaching a vacuum, though absolute vacuum is impossible), while on the other side, it maintains atmospheric pressure. This creates negative pressure, generating a suction force or a pushing force, thus achieving power assistance. Introduction to Vacuum Pumps: A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and achieve a vacuum. In simpler terms, a vacuum pump is an apparatus that improves, generates, and maintains a vacuum in a sealed space through various methods. A vacuum booster pump is a large-diameter chamber, mainly composed of components such as the pump body, rotor, slider, pump cover, gears, and sealing rings. Note: Inside, there is a diaphragm (or piston) with a push rod in the middle, dividing the chamber into two parts—one connected to the atmosphere and the other linked to the engine intake manifold via a pipe. Working Principle of Automotive Vacuum Pumps: For vehicles with gasoline engines, which generally use spark ignition, a relatively high vacuum pressure can be generated at the intake manifold, providing sufficient vacuum source for the vacuum-assisted braking system. However, for vehicles powered by diesel engines, because the engine uses compression ignition, the intake manifold cannot provide the same level of vacuum pressure, requiring the use of a vacuum pump to supply the vacuum source. Additionally, some engines designed to meet certain automotive emission and environmental requirements also need a vacuum pump to provide adequate vacuum source to ensure the vehicle operates properly. The vacuum pump primarily outputs the pressure generated by the power servo system. However, in cases where the vacuum pump fails to function normally, the hydraulic system can still be manually operated to provide power assistance.
