It depends on the situation, as the antifreeze has a service life of approximately two years. If it has been more than two years, it is recommended to directly replace it with new antifreeze. If it has not yet reached two years, you can top it up appropriately. Below is relevant information about antifreeze: Composition: Antifreeze is mainly composed of ethylene glycol and water, meaning it is an aqueous solution of ethylene glycol with certain conductivity. Function: Antifreeze prevents the coolant from freezing and expanding in cold winter conditions when the vehicle is parked, which could crack the radiator or damage the engine cylinder block or head. Antifreeze is not just for winter use; it should be used all year round. Regardless of the color of the antifreeze, it should maintain a certain level of transparency. A cloudy product is not a good one.

How much battery degradation in the BYD Tang qualifies for a free replacement?

BYD Tang's power battery experiences significant degradation after 2-3 years of use, and after three years, the level of degradation can affect normal operation. Therefore, the manufacturer offers free replacement when the battery degrades to a certain extent. Below is additional information: Car battery: A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. Typically, what people refer to as a car battery is a lead-acid battery, which is mainly composed of lead and its oxides, with sulfuric acid solution as the electrolyte. The electrodes of a standard battery are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; the disadvantages include low specific energy (the amount of electrical energy stored per kilogram of battery), short service life, and frequent maintenance requirements.

How to Remove a Car Wheel?

Method for removing a car wheel: First, prepare the necessary tools, then remove the screw caps and loosen the screws. After that, use a jack to lift the car and the tire can be removed. Note that you should not lift the car at the beginning of the removal process. When loosening the fixing screws, pay attention to the direction of force—counterclockwise to loosen the screws and clockwise to tighten them. After loosening all the screws one by one, use the jack to partially lift the vehicle. Car tires are one of the important components of a car. Tires are the parts that come into contact with the road surface and interact with the car's suspension to absorb shocks generated during driving, ensuring a comfortable and smooth ride. Car tires are consumables; prolonged contact with the ground causes wear. When the wear reaches a certain level, the tires need to be replaced promptly. Additionally, always monitor the tire pressure during daily use to ensure it remains within the normal range, maintaining the car's optimal working condition.

What to Do If Someone Is Locked Inside a Car?

Open the central locking system inside the car to unlock the doors. Here are the corresponding solutions if someone is locked inside a car: 1. Have a phone: If you have a phone with you, call 119 for emergency assistance. Calling 110 also works. 2. Break the window: Don't break any window randomly, as the cost varies for each piece of glass—some are expensive, and some are cheaper. For sedan windows, the price from highest to lowest is as follows: triangular window, sunroof glass, front windshield, rear windshield, and the four side windows (the rear side windows are slightly cheaper than the front ones). 3. Use a wire to hook the central lock: Generally, 4S shops or professional auto repair shops have a tool similar to a balloon (only the principle is like a balloon, but it is completely different). First, insert it into the door gap, then inflate it to widen the gap, allowing the wire to be inserted. Afterward, just restore the door to its original state.

Why does a car stall while driving?

Stalling caused by carbon deposits, especially at the electronic throttle, which is an intake system fault. Here is a related introduction about stalling: 1. Reasons for stalling: The use of inferior fuel (many gas stations sell impure fuel for huge profits) leads to engine carbon deposits and stalling, or due to spark plug or ignition coil failure, causing one or more cylinders to misfire, resulting in stalling. 2. Solutions: Stalling at idle: When the vehicle is idling, the speed is not very fast, and you only need to restart the engine after stalling. For automatic transmission vehicles, you must shift the gear to park or neutral before restarting the engine.
