Reasons for the engine light on the car dashboard to illuminate: When the battery is dead, not only does the battery indicator light up, but the engine fault light will also illuminate. Newly purchased cars that are not maintained according to regulations will cause the engine fault light to come on. When the engine oil is insufficient, the engine oil indicator light will illuminate, and the engine fault light will also come on. Lack of various fluids such as antifreeze, brake fluid, power steering fluid, etc., will generally cause the engine fault light to illuminate. Sometimes there may be no actual car issues, but the electronic system gives a false alarm, or the fault light remains on due to a previous issue (e.g., missing something) that was fixed but the fault code was not cleared. If the engine fault light is on, it does not necessarily mean the engine cannot operate. First, when the fault light is on, it needs to be checked and repaired. If you happen to be near a repair shop, you can have it checked immediately. It is best to inspect it right away. If you are far from a repair shop and do not have time to go for an inspection, as long as you feel there are no obvious engine issues, you can proceed with your tasks. When the engine fault light is on, if there are no obvious faults, driving cautiously at low speed is usually sufficient. There might be minor issues or no issues at all. However, if the engine exhibits obvious faults, such as severe abnormal noises, significant vibrations, or smoke coming from the engine, do not drive the car. It is best to contact a repair shop and wait for assistance.

What to Do If the Passenger Window Was Left Open During Rain and Water Got Inside the Car?

Methods to handle water ingress in the passenger side are as follows: 1. Minor splashing or water ingress: Remove the wet floor mats, carpets, and seat covers, clean them with automotive-specific detergent, and let them dry. Then, extract any standing water in the car, clean the area again, and let it dry. Check nearby electronic devices for any moisture exposure; if found, dry them thoroughly before testing. 2. Severe water ingress: First, remove the floor mats and floor coverings, then locate the sealing plugs at the bottom of the car's chassis and open them to drain the accumulated water. Clean the floor mats, seat covers, and other interior components as described above. If the seat foam has absorbed water, remove the seats for drying to prevent long-term rotting. After the car has dried, inspect the wiring system and electronic devices for any damage and replace components as necessary.

What are the conditions for wheel balancing of a car?

When a car tire cannot maintain balance in a stationary or moving state, wheel balancing should be performed. The following is a detailed introduction about wheel balancing for cars: 1. Classification: Wheel balancing mainly includes static balance and dynamic balance. When replacing tires, balancing should be performed again. Static balance refers to the mass equilibrium around the tire. Dynamic balance refers to the mass equilibrium along the axial direction of the tire. 2. Others: The tires have already been balanced when the car leaves the factory. However, during the use of the vehicle, the balance system may be disrupted. In addition, when replacing tires, balancing should also be performed. Wheel balancing should be carried out on a specialized dynamic balancing machine.

What Vehicles Are Suitable for Diesel 20W50 Engine Oil?

Diesel 20W50 engine oil is suitable for vehicles that require high viscosity but should not be used in excessively low temperatures. Below are some issues related to selecting excessively high viscosity: 1. Difficulty in cold engine starts: If the engine oil viscosity is too high, its flow becomes sluggish. Although oil pressure may be high, the amount of oil passing through is limited, especially during cold starts when oil cannot promptly reach friction surfaces. This often leads to temporary dry or semi-fluid friction, accelerating component wear. 2. Reduced engine effective power: Higher oil viscosity increases frictional resistance on engine component surfaces. Given the extensive friction areas within an automotive engine, even a slight increase in oil viscosity can significantly amplify frictional power loss when components move at high speeds. Overcoming this increased friction requires additional fuel consumption.

How to Straighten the Steering Wheel After Turning Right?

When the steering wheel is turned to the right, it needs to be corrected. Here are methods to determine if the steering wheel is straightened: 1. Turn the steering wheel 90 degrees left and right while stationary to feel its weight: when the steering wheel is straightened, turning it 90 degrees feels lighter, whereas turning it one full turn and then 90 degrees feels tighter. 2. Use forward or backward movement to check if the steering wheel is straight: after parking, moving slightly forward or backward can help determine if the steering wheel is straight, allowing for timely adjustments while moving. 3. Observe the tire direction: if conditions permit while parking, you can lean out the window to check if the tires are straight. Observing while driving makes it easier to straighten the steering wheel. 4. Look at the steering wheel emblem: whether the steering wheel is turned half a turn or fully, there's no need to worry about the exact degrees when straightening it—simply ensure the emblem returns to the upward position.

Can You Still Drive When the Car ESC Shows a Malfunction?

When the car's ESC malfunctions, it is best to go to a 4S shop or repair shop for inspection. Continuing to drive may pose risks. Here are some relevant details: 1. The ESC system is the car's Electronic Stability Control system, which is part of the driving assistance system. If the ESC system is damaged, the car may lose control under certain circumstances, which can be very dangerous. 2. There are many assistance systems in a car, such as the Anti-lock Braking System (ABS), Brake Force Distribution System (EBD), and Electronic Stability Program (ESP). These systems can help prevent the vehicle from losing control in certain situations. 3. When an assistance system malfunctions, it needs to be repaired immediately; otherwise, it may pose risks under certain conditions. A malfunction in an assistance system may not necessarily be due to the system itself but could be caused by a faulty sensor.
