Why Doesn't the Negative Terminal of a Car Battery Have a Cover?
1 Answers
The car's negative terminal is connected to the vehicle body, making the entire body act as the battery's negative terminal, so there's no risk in connecting the battery to the body. However, the positive terminal must never come into contact with the body, hence it is covered for protection. Below are specific details about car maintenance: 1. Engine oil level check: Park the vehicle on a level surface. Pull out the dipstick to check the oil level; if it's between the F and L marks, it's within the normal range. 2. Brake fluid level check: If the brake fluid is near or below the lower limit, it may indicate a leak in the system or excessive wear of the brake pads, and you should promptly visit a service station for inspection. 3. Battery maintenance check: Ensure the battery is securely fastened, and the electrolyte level is between the upper and lower limits. If it's close to the lower limit, promptly top up with electrolyte or distilled water to the upper line. Maintain good contact of the battery's positive and negative cables, and keep the battery clean and dry. 4. Tire check: Check the tire pressure monthly at normal temperature. If the pressure is below the standard, promptly inflate the tires. The pressure should not be too high or too low, as it affects driving safety.
