Why Does the Car's Cooling Fan Keep Running?

Car's cooling fan keeps running due to faults in the fan assembly, wiring issues, or excessively high water temperature. Below is an introduction to the car radiator and its working principle: Car Radiator: Also known as the heat exchanger, it is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. Working Principle: The radiator is a crucial part of a water-cooled engine. As an essential component of the engine's cooling circuit, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature rise after absorbing the engine block's heat is not significant. Thus, the engine's heat is transferred through the liquid coolant circuit, using water as the heat carrier. The heat is then dissipated via large-area cooling fins through convection, maintaining the engine's optimal operating temperature.

Can I take the Subject 2 driving test if my ID card has expired?

You cannot take the driving test with an expired ID card, but you can use the expired ID to apply for a temporary resident ID card to continue the test. Here is relevant information: Introduction: The driving license, also known as a "driver's license," is a legally required document for motor vehicle drivers. License renewal period: If a driver has not accumulated 12 penalty points in any scoring cycle during the six-year validity period of the license, they can renew it for a ten-year validity period. If they continue to maintain this record during the ten-year validity period, they can obtain a long-term valid driving license.

What to Do If the Motorcycle Stalls After Starting?

If a motorcycle stalls after starting, it may be due to a lack of fuel in the tank. The reasons for a motorcycle stalling are as follows: 1. Reason one: The motorcycle may automatically stop due to the inability to supply fuel normally. During normal motorcycle operation, if fuel is missing, a noticeable decrease in power will be felt before stopping, followed by a gradual halt. 2. Reason two: If the engine temperature is too high, it may also cause stalling. This is because excessive engine temperature leads to poor lubrication of internal engine components, causing wear between the piston and cylinder, which can also result in engine stalling.

What Does Air Suspension Mean?

Air suspension generally refers to the air suspension system. The following is extended information about air suspension: 1. Air suspension is a type of car suspension: It usually consists of an air compressor, an accumulator, a control unit, front and rear axle body height sensors, 3 body acceleration sensors in different directions, and 4 air spring extension acceleration sensors. 2. Its main principle is: The sensors transmit the collected signals to the control unit, which calculates and issues commands to adjust the hardness of the air springs and the damping of the shock absorbers. 3. Achieving the most ideal elastic state, the reflection process only takes a few microseconds: Therefore, the air suspension system responds to every tiny movement of the wheels and takes appropriate action.

Where is the auxiliary battery of Mercedes-Benz located?

Mercedes-Benz's auxiliary battery is located on the right side of the trunk. The auxiliary battery is an important component in the vehicle, responsible for powering all electronic devices in the car and also for starting the engine. When the car's alternator is not generating electricity or the voltage is very low, the electrical energy required by the engine ignition system and the vehicle's electrical equipment is entirely supplied by the auxiliary battery. The battery is a wear-prone component that requires frequent replacement. Avoid sitting in the car for extended periods using electronic devices without starting the engine. When parking overnight in winter, try to avoid leaving the car outside all night. If the car is not driven for a long time, the negative terminal of the battery can be disconnected to prevent battery discharge.

Is Mercedes-Benz's 4matic a four-wheel drive system?

Mercedes-Benz's 4matic is indeed a four-wheel drive system. Models with the 4matic badge on the rear are equipped with this system, which is a full-time four-wheel drive system. Vehicles with full-time four-wheel drive always have power distributed to all four wheels, improving mechanical grip, handling, and driving stability. Part-time four-wheel drive systems are typically used only in rugged off-road vehicles. Vehicles equipped with part-time four-wheel drive have three modes: high-range four-wheel drive, low-range four-wheel drive, and high-range two-wheel drive. When switched to low-range four-wheel drive mode, the vehicle's wheel torque increases, enhancing its off-road capability and ability to escape difficult terrain.
