What items are included in the second maintenance?

The second maintenance for a car includes changing the engine oil, air conditioning filter, oil filter, air filter, as well as inspecting the engine and tire conditions. Additionally, a comprehensive cleaning of the vehicle will be performed. Below is a detailed explanation: 1. Changing the engine oil and filter: The second maintenance will definitely involve changing the engine oil. The oil typically replaced by 4S shops is semi-synthetic, which is of lower quality compared to fully synthetic oil. If desired, you can request fully synthetic oil, though this will require an additional cost. Along with the oil change, the condition of the oil filter will also be checked, and it will be replaced if necessary. 2. Inspecting the engine and other components: The second maintenance will also include checking the engine's working condition, such as whether the pipe connections are normal, if there are any leaks, if the engine sounds normal, or if there are any unusual noises. Furthermore, the vehicle will be lifted to inspect the undercarriage for any scratches or corrosion, as well as to check the braking system, suspension system, and the inner side of the tires to ensure safety for future use.

Here are the steps to loosen the negative terminal of a car battery: 1. Unscrew the two fastening buttons of the heat insulation cover, then lift the red and black insulation caps on the positive and negative terminals (red for positive, black for negative). 2. Use a wrench to loosen the fastening nut on the negative terminal of the battery, then gently pry open the fastening block with a flat-head screwdriver to remove the negative terminal. Here is some related information about car batteries: 1. The negative terminal of the car is connected to the car body, which is made of metal. The entire car body acts as the negative terminal, meaning the car body itself can be considered the negative terminal. 2. Most disassembly tools are made of metal. If a metal tool touches a metal part of the car body, the positive and negative terminals may directly connect, forming a circuit. This can cause the electrode to melt, potentially damaging the battery or even leading to a fire.
