Should the Positive or Negative Terminal Be Removed First When Disconnecting a Car Battery?

Remove the negative terminal first. Below are the relevant steps for battery removal: 1. Before replacing the battery, check if it is completely depleted. If the battery is cracked, replace it immediately. If not, inspect both terminals first. Sulfate buildup can corrode the battery terminals. Use a brush dipped in a mixture of baking soda and water to clean them. 2. Turn off the engine before replacement. Carefully loosen the battery screw connected to the negative terminal with a wrench and remove the cable clamp from the terminal. Repeat the same process for the positive terminal. Firmly grasp the battery and remove it from the vehicle. After removal, clean the clamps and battery tray with soda water. 3. During installation, carefully place the new battery in the battery tray. Ensure the positive and negative terminals are correctly positioned, then secure the battery by tightening the bracket. Attach the cable clamps to the positive and negative terminals. Finally, close the hood.

What are the causes of idle vibration in new cars?

New car idle vibration can be caused by poor fuel combustion, insufficient ignition energy due to spark plug failure, air leakage in the intake system or low fuel pressure, poor fuel injector atomization, improper idle adjustment, malfunctioning idle control valve or bypass air valve, carbon buildup on valves and intake ports, etc. Here is the relevant content introduction: Intake manifold or various valve leaks. When unwanted air, gasoline vapor, or combustion exhaust enters the intake manifold, it can cause the air-fuel mixture to become too rich or too lean, leading to abnormal engine combustion. When the leakage affects only individual cylinders, the engine will experience more severe vibration, which has a greater impact on new car idle conditions.

Is Engine Oil the Same as Transmission Fluid?

Engine oil and transmission fluid are not the same. Here are the relevant details: 1. Engine oil is the lubricant for the engine system, possessing properties such as oxidation resistance, wear resistance, and corrosion prevention. Transmission fluid, on the other hand, is primarily used to keep the gear system clean, ensuring the transmission operates normally and extending the lifespan of the transmission components. 2. Transmission fluid is an oil-based product designed to maintain the cleanliness of the gear system, ensuring proper transmission function and prolonging the service life of the transmission components. Most transmission fluids are compatible with automatic transmissions on the market. However, each automatic transmission design has unique technical requirements. Even the same model of transmission configured in different vehicle models may differ in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluid. Different transmission fluids can significantly impact shift quality.
