Reasons for the Car Not Starting and Dashboard Flashing?

Car not starting and dashboard flashing is due to a dead battery. Here is relevant information about the car not starting: 1. When the engine is not started, the battery supplies power to all electrical devices in the car and is also responsible for starting the engine. 2. After starting the engine, the engine can drive the generator to operate, at which point the generator can charge the battery and also supply power to the car's electrical devices. 3. When starting the engine, the starter needs to operate, the fuel supply system needs to operate, and the ignition system needs to operate—all these systems require electricity to function. 4. When starting the engine, the battery needs to release a large current. If the battery's performance is poor, it may result in difficulty starting the engine or even complete failure to start. 5. The battery is a wearable part that needs regular replacement. As the number of charge and discharge cycles increases, the battery's performance will decline, so it needs to be replaced periodically. 6. Under normal circumstances, a battery can last 3 to 4 years.

How Often Should the Coolant in a Car Be Replaced?

Vehicle coolant generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each car, the replacement should be based on actual usage. Check the coolant level regularly; if it is insufficient, top it up promptly. If suspended particles, sediment, or signs of deterioration or discoloration are found in the coolant, replace it immediately and clean the system. Coolant Replacement Method: Before completely replacing the coolant, conduct a thorough inspection to check for any leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose is named for its five connection points that distribute coolant to different parts of the car. If there are any signs of coolant leakage in this area, replace the hose or reseal the connections as needed. Drain the old coolant and flush the system with clean water. Add water to the coolant reservoir and continue filling until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pink. Continue flushing until the water runs clear. Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, fill the coolant reservoir with another bottle of coolant until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Top up the coolant to the "MAX" mark on the reservoir.

When to Turn the Steering Wheel for Left and Right Turns?

Timing for turning the steering wheel during left and right turns: 1. For a left turn on a narrow road, turn the wheel when the right front corner of the car aligns with the roadside; on a wide road, you can turn slightly earlier. 2. For a right turn on a narrow road, turn the wheel when the left front corner of the car aligns with the roadside; on a wide road, you can turn slightly earlier. 3. Principle for turning the wheel: gentle turns (turn early, turn slowly; return early, return slowly), sharp turns (turn late, turn quickly; return early, return quickly). 4. During turns, be careful not to scrape the right side or have the rear wheels go off the road, and pay attention to the inner wheel difference. 5. If there are obstacles on the roadside, start turning the wheel when the car is almost parallel with the obstacle. Begin returning the wheel when the car is about to straighten but not completely straight after the turn. 6. Do not wait until the car is completely straight to return the wheel; there is a process from turning the wheel to straightening the car.

What to Do If a Car Hasn't Been Driven for a Long Time?

Precautions for a car that hasn't been driven for a long time: 1. Pay attention to protecting the paint surface of the car body: Leaves, dust, broken branches, etc., can damage the paint or even cause rust. Before long-term parking, give the car a thorough cleaning, wash it, and apply wax to protect the paint, which helps prevent corrosion and oxidation. 2. During the idle period, it's best to check the battery every two weeks. For example, check the height of the electrolyte. Generally, the electrolyte level should be 10-15mm above the plates. If it's insufficient, add distilled water promptly. Start the car for 5-10 minutes every one or two weeks to charge the battery, and also check for any other issues with the vehicle. 3. Tires may lose air during long-term parking. There are two main reasons for this: Human factors: In unattended parking lots or residential areas, someone might remove the valve core or puncture the tire. Natural factors: If the tires have been used for a long time, the valve core may age; repaired tires may develop leaks over time; or the wheel rim may be dented, causing a gap between the rim and tire, leading to air loss. 4. Rubber components, such as window seals, drive belts, and some hoses inside the car, are made of rubber. Exposure to wind, sun, and especially sunlight and low temperatures can accelerate rubber aging. Contact with gasoline or oil can cause rubber to swell, loosen, and lose elasticity. 5. When the car is idle for a long time, avoid leaving food or drinks inside. Opened food and drinks can mold within three or four days, causing air pollution inside the car.

How Does a Car Air Conditioner Cool?

Methods for car air conditioning cooling: 1. Press the AC button when cooling, then the compressor clutch will engage, allowing the engine to drive the compressor. 2. To turn on the cold air, adjust the button towards the blue area. Below is relevant information about air conditioning cooling: 1. When the compressor is running, it continuously compresses the refrigerant and delivers it to the evaporator. 2. The refrigerant absorbs heat in the evaporator, cooling it. The cooled evaporator then cools the air blown by the blower, allowing the car air conditioner vents to blow cold air. 3. The car air conditioner filter also needs to be replaced regularly. If not replaced for a long time, it will affect the air quality inside the car. 4. The car air conditioner also needs regular cleaning and disinfection. If not cleaned and disinfected for a long time, many bacteria will grow in the car's air conditioning system, which can harm the health of passengers. 5. It is recommended to regularly clean the car's air conditioning system during normal use.
