Possible causes of car radiator leakage include: hose rupture, oil emulsification, improperly secured radiator cap, rubber hose joint leakage, cooling tube rupture, and radiator cracking. Here is an introduction to car radiators: 1. The car radiator, also known as the heat exchanger, is a key component in the automotive cooling system. 2. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, then returns to the water jacket in a continuous cycle, achieving temperature regulation through heat dissipation. 3. The radiator is a crucial part of water-cooled engines, absorbing heat from the engine block to prevent overheating. Due to water's high specific heat capacity, its temperature doesn't rise significantly after absorbing engine heat. The engine's heat is transferred through the coolant circuit using water as a thermal conductor, then dissipated via large-area cooling fins through convection, maintaining the engine's optimal operating temperature.

I've been driving for over a decade and often encounter radiator leaks, mainly due to aging or external damage. If a radiator has been used for a long time, the metal inside can rust and corrode, forming small cracks that slowly leak water. For example, a stone flying on the road might puncture it, or an accident could deform or crack the radiator. Another common factor is a loose radiator cap with poor sealing, making it prone to leak coolant when the cooling system pressure rises. Once, my car leaked on the highway because of an aged connector. I had to pull over and add water as an emergency measure, but don't drive for too long like that, or the engine could overheat and get damaged, costing a fortune. For daily prevention, I recommend flushing the radiator every six months to prevent sediment buildup and using antifreeze instead of plain water for better corrosion resistance. If you notice an issue, check it immediately—a simple test is using a flashlight to spot leaks or adding dye to trace them. Fix minor repairs promptly to avoid expensive part replacements later.

What is the method to determine a 30 cm distance between the car body and the roadside?

Methods to determine a 30 cm distance between the car body and the roadside include observing the position of the wiper protrusion and checking in the rearview mirror whether the rear door handle aligns with the sideline. In driving license tests, many scenarios require the distance between the car body and the sideline to be within 30 cm. When parking by the roadside, it is essential to carefully observe the parking space and check for any obstacles in front or behind. In areas with heavy traffic, drivers should always check the rearview mirror for approaching vehicles before opening the door to exit, to prevent collisions. Methods to maintain a 30 cm distance between the car body and the roadside: 1. Observe the position of the wiper protrusion: The wiper is a standard feature on every car, and its protruding part is easily noticeable when flat. During driving tests, you can determine the distance between the car and the sideline by checking if the wiper protrusion aligns with the right sideline. When they align, the distance is exactly 30 cm. 2. Check the rear door handle in the rearview mirror: During tests, when the position of the rear door handle reflected in the rearview mirror aligns with the sideline, the distance between the car and the sideline is exactly 30 cm.

How to Reinspect a Vehicle That Has Not Been Inspected for Three Years?

The vehicle owner needs to personally submit a written application for reinspection to the traffic police department. Required documents include the vehicle license, third-party liability insurance certificate, and the original and copies of the vehicle and vessel tax. During the reinspection, fines must be paid, and 3 points will be deducted from the driver's license. According to the Road Traffic Law, vehicles that have not undergone the mandatory safety technical inspection (annual inspection) on time are not allowed to be driven on the road. Violators will be fined and have 3 points deducted from their license. In case of any traffic accident caused by the failure to undergo the annual inspection, the party involved will bear full or primary responsibility. Moreover, driving without inspection is considered illegal, and insurance will not cover any claims. The "Road Traffic Safety Law Implementation Regulations" stipulate: Article 16: Motor vehicles must undergo safety technical inspections according to the following intervals from the date of registration: passenger vehicles for commercial use must be inspected once a year within 5 years; after 5 years, once every 6 months; trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within 10 years; after 10 years, once every 6 months. Required documents: ID card, vehicle license, compulsory traffic insurance policy, vehicle and vessel tax invoice (it's advisable to bring all relevant materials in case they are needed). The inspection must be conducted within the validity period of the compulsory traffic insurance. If the insurance has expired, it should be renewed before the inspection. All violations must be cleared. Essential items like a fire extinguisher and warning triangle are mandatory. Ensure that lights, brakes, etc., are functioning properly. The vehicle's appearance, including color and logos, must match the registration details. Owners with modifications are advised to remove them before the inspection.

What is the purpose of placing the electric fuel pump inside the fuel tank?

The purpose of placing the electric fuel pump inside the fuel tank is to pump the combustion gasoline from the fuel tank into the fuel line and maintain a certain pressure to supply the fuel injector and cold start valve. Its function is to transport fuel from the fuel tank to the engine in the gasoline or diesel engine fuel supply system. Electric fuel pumps can be divided into roller type, turbine type, rotor type, and side channel type according to their different structures. According to the installation location, they can be divided into built-in type and external type. Principle of fuel pump structural forms: Vane pump (turbine pump) characteristics: The pulsation of oil pressure is small, the operation is smooth, the noise is low, and a pulsation damper is not required in the fuel supply system. It is easy to miniaturize, but the delivery efficiency is relatively low. Positive displacement pump roller type rotor type vane type characteristics: The oil pressure is high, but because the operation is not continuous, the oil pressure pulsation is large. Therefore, a pulsation damper is also required at the outlet end of the fuel pump. The turbine-type electric fuel pump is mainly composed of an electric motor, turbine pump, check valve, and safety valve. When the fuel pump is energized, the motor drives the turbine pump blades to rotate. Due to centrifugal force, the blades around the impeller press against the pump housing, carrying fuel from the inlet chamber to the outlet chamber. As the fuel in the inlet chamber continues to increase, a certain degree of vacuum is formed, sucking fuel from the inlet. The fuel in the outlet chamber continues to increase, and the fuel pressure rises. When it reaches a certain value, the outlet valve opens to output fuel. The outlet valve prevents fuel from flowing back to the fuel tank when the fuel pump is not working, maintaining a certain pressure in the fuel line to facilitate the next startup.

What is Automotive Urea?

Automotive urea is a colorless, transparent liquid stored in a urea tank. When sensors detect nitrogen oxides in the exhaust pipe, it automatically sprays mist-like automotive urea, which mixes with nitrogen oxides and undergoes redox reactions in the SCR reaction tank, ultimately producing non-polluting nitrogen and water for emission. Vehicles have a dedicated urea tank where the urea is filled. As long as the vehicle is running, urea will be consumed, so it needs to be replenished promptly. Generally, about 4 liters of urea are consumed per 100 liters of diesel, depending on factors such as engine displacement, model, and manufacturer.
