When Does the Car Fan Turn On?

The radiator fan in a car operates based on the coolant temperature, typically activating when the temperature reaches around 80-90 degrees Celsius. The reasons why a car radiator fan may not turn on are as follows: 1. Whether the coolant temperature meets the requirement: With the continuous advancement of automobiles, many car radiator fans now operate electronically based on temperature control. During driving, the radiator fan will only turn on when the coolant reaches the required temperature. If the coolant temperature in the radiator does not meet the requirement, the fan will not operate, indicating that the fan is not faulty but that the coolant temperature needs to be checked. 2. Relay failure: If inspection shows that the coolant temperature has reached the threshold for the fan to operate, but the engine's radiator fan still does not work, it may be due to a faulty relay. A malfunctioning relay cannot transmit signals, preventing the radiator fan from operating. 3. Thermostat switch issue: If all the above components are confirmed to be functioning properly, the thermostat switch should be inspected. A faulty thermostat switch can also disrupt the normal operation of the radiator fan.

What is the Difference Between Parking Lights and Brake Lights?

Parking lights and brake lights differ in brightness, power consumption, wattage, and function. The specific details are as follows: Brightness: Brake lights are brighter than parking lights. Additionally, parking lights and brake lights do not use the same bulb. Brake lights have a larger surface area and stronger light penetration, similar to fog lights. Power Consumption: Parking lights consume very little power (not the same as the light setting before turning on the headlights). They illuminate during nighttime parking to prevent other moving objects from colliding with the car and require manual activation. The method to activate parking lights varies by car manufacturer. Wattage: Brake lights have high wattage and are red in color. They only illuminate when the vehicle is braking and are controlled either by linkage with the brake pedal or automatically by braking force. Function: Parking lights serve as warning lights under conditions where the car is equipped with them. They provide a safety reminder to the surrounding environment, such as other vehicles and pedestrians, when temporarily parked and the engine is off, to indicate the car's position.

What does a yellow light with an 'a' inside a circle on the dashboard mean?

A yellow light with an 'a' inside a circle on the dashboard indicates that the engine auto start-stop system is active. In this state, the car may shut off, and releasing the brake will automatically restart the engine, allowing normal driving to resume. The auto start-stop system activates under the following conditions: when the coolant temperature is too low after a cold start (below 70 degrees Celsius); when the outside temperature is below 5 degrees Celsius, or when the interior temperature is below 20 degrees Celsius after turning on the heater; when the battery charge is insufficient (typically below 60%); when the steering wheel angle exceeds 30 degrees; when the front seat belts are not fastened; or when parking on a slope. The auto start-stop function activates automatically each time the car is started, provided the above conditions are met, the vehicle speed exceeds 3 km/h, and the condition persists for about 4 seconds, without requiring any additional driver input. However, the auto start-stop function must be turned off in the following situations: during water fording; when driving on a slope (most cars are typically set to automatically disable it in this scenario); and when refueling, as the engine must be completely shut off and the power turned off before refueling.

What are the advantages of a multifunction steering wheel?

The benefits of a multifunction steering wheel lie in the fact that the driver can directly operate some of the vehicle's electronic devices from the steering wheel itself, eliminating the need to search for various buttons on the center console. This allows the driver to focus more on the road ahead, enhancing driving safety. Although most functions are limited to audio control, it provides considerable convenience and enjoyment for family cars. When installing a multifunction steering wheel, pay attention to the following: Airbag: Never tamper with parts marked with 'airbag' or similar labels, as this is the driver's airbag, typically located in the center box of the steering wheel. The additional components of a multifunction steering wheel are usually control buttons. If installation is necessary, refer to the configuration of higher-end models of the same type, which typically have controls on the decorative strips on either side of the airbag. When installing on the original steering wheel, ensure that wiring does not interfere with the airbag's detonation line. As long as the airbag boundaries remain untouched, normal deployment should not be an issue. Do not replace the steering wheel: The original airbag, steering wheel, steering column, and even the vehicle body's protective effects in a collision are all nationally certified. Replacing them voids this guarantee. Do not assume that having an airbag means the steering wheel is irrelevant in a collision. In crash tests, it is common to see steering wheels bent after airbag deployment, serving to absorb energy and mitigate impact.

What Does the Car's Internal Circulation Mean?

Internal circulation refers to the state of a car's air system where the air exchange channels between the inside and outside of the vehicle are closed. When the fan is off, the air inside the car does not circulate; when the fan is on, the airflow drawn in comes solely from within the vehicle, creating an internal air circulation loop. The primary function of internal circulation is to promptly and effectively prevent external dust and harmful gases from entering the car. It helps warm up the car faster in winter and cool it down more quickly in summer when the air conditioning is on. It can also be used during smoggy days. Essentially, internal circulation keeps the air inside the car recirculating, maintaining the interior temperature more effectively. While it aids in faster heating or cooling, it's important to note that internal circulation should not be used for extended periods while driving. The car cabin is a relatively sealed environment, and prolonged use of internal circulation can reduce oxygen levels inside, leading to fatigue and drowsiness, which can compromise driving safety. When to Choose Internal vs. External Circulation: Consider road conditions: On highways, use external circulation. Firstly, due to wind resistance and high speeds, opening windows is impractical. Prolonged use of internal circulation can cause brain hypoxia, impairing reaction times and judgment, which is highly dangerous. Secondly, air quality on highways is generally good, with low exhaust concentrations, making external circulation a viable option. In congested urban areas or during rush hours, where vehicle exhaust levels are high, it's advisable to switch to internal circulation. Consider the car's condition: New cars often contain higher concentrations of toxic gases like formaldehyde. For the first three to six months after purchasing a new car, it's recommended to use external circulation along with opening windows to enhance air circulation and dilute the toxic gas levels inside. Consider air quality: In regions where PM2.5 pollution is severe (PM2.5 levels above 50), and air quality is not good, it's best to use internal circulation to avoid inhaling excessive PM2.5 particles. The Role of External Circulation: External circulation ventilates the car, expelling stale, oxygen-depleted air and bringing in fresh air. In winter, if the heater is on, remember to switch to external circulation to prevent dizziness and chest tightness.
