What items are required for the second car maintenance?

The items required for the second maintenance include: replacing the engine oil and oil filter, replacing or cleaning the air and cabin air filters, and inspecting and maintaining dozens of items across multiple systems such as the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Precautions for car maintenance are as follows: 1. Regularly check whether antifreeze, brake fluid, windshield washer fluid, etc. are sufficient. Antifreeze ensures normal driving in winter and prevents freezing. Brake fluid is an essential component of the braking system. Windshield washer fluid is used to clean the windshield. All these must be kept at adequate levels to ensure the vehicle operates properly. 2. Perform wheel alignment regularly. 3. Regularly inspect the brake pads. Check the wear level of the brake pads and clutch plates periodically. When driving on the road, the brake pads and clutch plates are constantly wearing out. They need to be replaced once they reach a certain level of wear; otherwise, there will be significant safety hazards.

When Should Car Brake Pads Be Replaced?

Here are the methods to determine when car brake pads need replacement: 1. Check the thickness. A new brake pad is generally about 1.5cm thick, and its thickness gradually decreases with continuous friction during use. When visual inspection shows that the brake pad thickness is only about 1/3 of the original (approximately 0.5cm), the owner should increase the frequency of self-inspection and be ready to replace them at any time. Of course, due to wheel hub design reasons, some car models do not allow visual inspection and require tire removal to complete the check. 2. Listen for sounds. If a 'metal-on-metal' squealing sound accompanies light braking (which could also be the effect of initial break-in after installation), the brake pads must be replaced immediately. This is because the wear indicators on both sides of the brake pads are already directly rubbing against the brake disc, indicating that the brake pads have exceeded their limit. In such cases, while replacing the brake pads, it is necessary to inspect the brake disc as well. Often, when this sound occurs, the brake disc has already been damaged. Even after replacing the new brake pads, the noise may persist, and in severe cases, the brake disc may need to be replaced. 3. Feel the resistance. If braking feels unusually strenuous, it is possible that the brake pads have largely lost their friction. In this case, they must be replaced immediately to avoid serious accidents.

What are the symptoms of oil emulsification?

The symptom of oil emulsification is the appearance of some white milky substances on the engine oil filler cap. The following are the hazards of oil emulsification: 1. When emulsified oil leaks water at places like the bearings of mechanical equipment, it is likely to destroy the oil film. 2. The emulsified liquid contains liquid water, which stays on the surface of mechanical parts, leading to rusting of equipment components and affecting the normal operation of the unit. 3. Emulsified oil deposits in the lubrication system, affecting the normal circulation of lubricating oil, resulting in insufficient oil supply to mechanical equipment and causing mechanical failures. 4. If emulsified oil is not treated in time with equipment such as oil filters, it will accelerate the overall aging of the oil. At the same time, the aged oil will produce harmful substances such as naphthenic acid soap and colloid, further accelerating the emulsification of healthy oil. 5. After the engine oil is emulsified, the lubricating effect of the engine oil is greatly reduced, increasing the friction coefficient among various mechanical equipment components. During the operation of mechanical equipment, bearings are very likely to be damaged due to overheating.

What is the numerical range for wheel alignment?

The standard data for wheel alignment are: the range of wheel camber angle is ±10 degrees; the range of toe angle is ±6 degrees; the range of caster angle is ±15 degrees; the range of kingpin inclination angle is ±20 degrees. However, since the size and chassis height of each vehicle are different, there is no exact value for the normal range of wheel alignment data. The best method is to check with an instrument. The instrument displays green as normal and red as abnormal. Wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure good driving performance and a certain level of reliability. The functions of wheel alignment include: maintaining the optimal driving angle between the tires and the body; reducing wear on the tires and steering components during driving; keeping the vehicle stable in straight-line driving and making steering easier; ensuring that the rear wheels or front wheels can automatically return to the correct position after steering. The following situations indicate that the vehicle needs wheel alignment correction: When driving, the vehicle is moving straight, but the steering wheel is tilted, or you feel heavy steering, shaking, or non-returning, then wheel alignment is needed; abnormal tire wear, such as wave-like wear, block wear, or uneven wear on one side, requires wheel alignment; if you feel floating, bumping, or swaying while driving, wheel alignment is needed; after repairing or replacing the suspension or steering system, wheel alignment should also be performed. When the wheel alignment data is abnormal, correction is necessary, especially if the vehicle frequently drives on bumpy roads, as the wheel alignment data is more likely to become inaccurate. Generally, it is recommended to perform wheel alignment every 10,000 kilometers or once a year to ensure driving safety and extend the lifespan of the tires.

How to Handle a Car Radiator Boiling Over?

Immediately park the car on a flat and safe area without obstructing traffic. Place a safety warning sign 50 meters behind the vehicle, or 150 meters if on a highway. Allow the engine to idle and open the hood to enhance heat dissipation. Once the temperature drops, add sufficient water to the radiator. Use a damp towel as a cushion when adding water.

Should You Press the Brake When Starting an Automatic Car?

Starting an automatic car requires pressing the brake. Here is the relevant information: 1. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, an automatic transmission has six gear positions, arranged from top to bottom as: P, R, N, D, S, and L. 2. Driving an automatic car primarily involves using the Park (P), Reverse (R), Neutral (N), and Drive (D) gears, which are sufficient for normal driving conditions. However, in certain special driving environments, other functional gears may be required. Therefore, by choosing the correct control method, an automatic car can perform even better than a manual transmission vehicle.
