If it is a standard model, a 17mm wrench is used. If a valve cover is used as a substitute, a 15mm wrench may be required. The functions of engine oil: Engine oil not only lubricates the engine but also serves to clean, seal, cushion, prevent rust, and dissipate heat. During engine operation, the oil forms a thin film on the surfaces of various components, preventing direct contact and friction between them. Precautions for oil change: If engine components come into direct contact and friction occurs, it will accelerate engine wear. Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failing to change the oil for an extended period will also increase engine wear.

How to Identify Battery Quality

There are several main methods to identify the quality of an electric vehicle battery: 1. Check whether the outer packaging is damaged or has been opened: When purchasing a battery, users should first check whether the outer packaging of the electric vehicle battery is damaged or shows signs of being opened. 2. Inspect the appearance of the battery itself: Open the packaging and examine the battery's appearance to see if there are any scratches or abrasions on the surface. 3. Check for rust on the metal terminals of the positive and negative electrodes: Look for anti-counterfeiting marks on the battery. If any of these criteria are not met, it is likely a refurbished battery or one that does not meet quality standards.

Should You Use Recirculation or Fresh Air Mode When Sleeping in the Car?

When resting in the car with the air conditioning on while parked, it is essential to periodically switch to fresh air mode or leave a slight gap in the window. Continuously using recirculation mode can lead to carbon dioxide poisoning. Here is a brief introduction to car air recirculation and fresh air modes: 1. Recirculation Mode: Recirculation mode is like an air-conditioned room with all doors and windows tightly closed, creating a completely sealed space. While this provides excellent cooling efficiency, prolonged use will make the air feel stuffy. 2. Fresh Air Mode: Fresh air mode is akin to an air-conditioned room with open doors and windows, maintaining air circulation for fresher air. However, the cooling effect will be significantly reduced.

Do tires have a front and back side when installing?

Tires have a front and back side, and owners need to pay attention to the front side markings during installation. The methods to distinguish the front and back sides are as follows: 1. Symmetrical tread tires: There is no distinction between front, back, left, right, inside, or outside during installation, but it is best to place the side with the production date on the outside. 2. Asymmetrical tread tires: During installation, the side with the letters "outside" should be placed on the outside. 3. Unidirectional tread tires: There is no distinction between inside and outside during installation, but it is recommended to place the side with the production date on the outside. Just make sure to install them according to the direction of the arrow, as the arrow indicates the rolling direction of the wheel.

What to Do When a Car Has Difficulty Starting After Being Parked for a Long Time?

If a car has difficulty starting after being parked for a long time, the solution is: first turn the key to the ON position, then briefly return it before turning it to the START position to ignite, allowing the computer to calculate the water temperature and appropriate air intake. Reasons why a car may have trouble starting after prolonged parking: 1. Poor fuel quality; 2. Lack of antifreeze; 3. Excessive carbon buildup in the vehicle. The car's ignition system is designed to ensure the proper operation of a spark-ignition engine by delivering a high-voltage electrical current (approximately 5,000 to 30,000V) to the spark plugs in the correct firing order, generating a strong enough spark to ignite the air-fuel mixture.
