How Often Should Engine Coolant Be Added?

Automotive antifreeze only needs to be replenished every two to three years. Methods for draining antifreeze: There are three locations where it can be fully drained: the lower part of the radiator; the lower part of the engine; and the small heater core inside the vehicle. It is important to note that after draining, the vehicle should be started for 5 seconds and then turned off (when the engine is cold). Precautions for replacing antifreeze: Generally, when replacing antifreeze, if the new antifreeze is of the same type (either ether or ethylene glycol), there is no need to worry about completely draining the old one. If switching to a different type of antifreeze, after draining the old antifreeze, you can add clean water 1-2 times, run the engine, and then add the new antifreeze. This minimizes the residual content of the old antifreeze. Even if some water remains, it won't cause any issues since all antifreeze contains water. After replacing with new antifreeze, be sure to check its specific gravity, as levels that are too high or too low are not ideal.

What is required to change the location of a driver's license?

To change the location of a driver's license, you need to bring your ID card, driver's license, and three one-inch color photos with a white background to the local vehicle management office to complete the transfer procedure for an out-of-town driver's license. For non-local residents, a residence permit is required, provided that the driver's license is in a normal status. Legal provisions: According to Article 58 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," if a motor vehicle driver's household registration is moved out of the jurisdiction of the original vehicle management office, they should apply for a license replacement at the vehicle management office of the new location. Detailed method: Motor vehicle drivers residing outside the jurisdiction of the issuing vehicle management office can apply for a license replacement at the vehicle management office of their residence. When applying, they should fill out an application form, submit the motor vehicle driver's identity proof and motor vehicle driver's license, and declare their physical condition.

Will driving in the wrong direction on the highway definitely be captured by cameras?

Driving in the wrong direction on the highway will definitely be captured by cameras. Generally, one-way road sections are equipped with surveillance cameras or electronic monitoring devices. Once a violation of driving in the wrong direction occurs, the probability of being captured is very high, almost 100%. Judgment when just entering the wrong direction: If you can promptly judge upon entering the wrong direction that it is a one-way road and you are going against traffic, you should make a U-turn as quickly as possible without affecting other vehicles and proceed in the correct direction. This may give you a chance to avoid being captured. (On highways, driving in the wrong direction, reversing, or making a U-turn is absolutely prohibited; you must proceed directly to the next exit.) Handling the situation if driving in the wrong direction: If you realize you are accidentally driving in the wrong direction on the highway, you should immediately pull over to the emergency lane while ensuring traffic safety, turn on the hazard lights, move to a safe area outside the guardrail, place a warning triangle 100 meters in front of the vehicle, and then contact the traffic police. Cooperate fully with the authorities when they arrive at the scene.

What kind of paint won't peel off when sprayed on plastic?

Plastic sprayed with air-drying acrylic paint won't peel off. This is commonly known as plastic paint. Air-drying acrylic coatings are mainly used in architectural coatings, plastic coatings, electronic coatings, road marking paints, etc. They have the advantages of rapid surface drying, easy application, and obvious protective and decorative effects. The disadvantages are that the solid content is not easy to be too high, hardness and elasticity are difficult to balance, a thick coating film cannot be obtained in one application, and the fullness of the coating film is not ideal. Characteristics of automotive paint: Automotive paint must not only have good mechanical properties, good fullness, and high gloss, but also have good adhesion, high hardness, and strong scratch resistance. At the same time, it must have good weather resistance, scratch and wear resistance, gloss durability, and excellent resistance to gasoline, alcohol, acid, alkali, and salt spray. Function of automotive paint: Automotive paint coating involves applying a film on the car's paint surface to protect the gloss of the paint from fading and to provide a physical protective film on the paint surface, thereby achieving the purpose of protecting the paint.

What Causes Low Oil Pressure at Idle Speed?

The reasons for low oil pressure at idle speed include: Malfunctioning oil pump: Insufficient oil level in the crankcase. The oil does not meet the required specifications, with viscosity being too low, meaning the oil is too thin. Effects of overly thin oil: The oil fails to meet specifications due to excessively low viscosity, or the oil level in the crankcase is too low. When the engine is idling, if the oil pressure is too low, it can lead to semi-dry or dry friction between the surfaces of moving parts, accelerating wear and tear, increasing clearance between components, and even causing bearing alloy to melt or peel off, resulting in abnormal noises. Introduction to engine idle: The oil pressure gauge reading during engine idle represents the idle working pressure of the fuel supply system, typically 0.25MPa or as specified by the vehicle's technical requirements. When testing idle working pressure, removing the vacuum tube from the fuel pressure regulator should cause the oil pressure to rise to 0.3MPa; otherwise, the oil pressure regulator should be replaced.

What is the reason for the failure of the spring brake after being flooded?

The reason why the spring brake cannot be used after being flooded: Generally, it is caused by the adhesion of the brake disc and brake pads, or rust at the fixed pin position of the brake caliper. Introduction to air brakes: Air brake is a braking method. On automobiles, a series of specialized devices used to apply a certain force from the external environment (mainly the road surface) to certain parts of the automobile (mainly the wheels), thereby imposing a certain degree of forced braking, are collectively referred to as the braking system. Automobile braking systems can be divided into service brakes (air brakes), parking brakes, emergency brakes, and auxiliary brakes according to their functions. Parking brakes can be further divided into central disc brakes and spring brakes, with the spring brake commonly known as the "spring brake". Composition of air brakes: A standard air brake system consists of the brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake, and air compressor. The brake control mechanism includes the brake pedal, pedal hanger, etc.; the dual-circuit brake mechanism includes the air reservoir, brake valve, low-pressure alarm, pressure regulator, brake pipe, directional valve, relay valve, safety valve, and drain valve; the central disc brake mechanism includes the parking brake control handle, brake cable, and central disc brake.
