What is the purpose of polishing?

1 Answers

Polishing is aimed at vehicle paint surfaces that have oxidation, dullness, or scratches, removing oxides and corrosive substances to restore the cleanliness of the paint surface. Here are some relevant details: 1. During the car detailing process, polishing is performed before waxing, sealing, or coating. This is because sealing and coating require prior polishing, and only a finely polished car can achieve a mirror-like finish. This step is essential for sealing. Without polishing, the paint surface remains uneven, causing the sealant to last only a short time and fail to provide long-term adhesion, making it no different from waxing. 2. Full-car polishing should not be done frequently, as excessive polishing can damage the paint. New cars should avoid full-car polishing within the first two years, while minor localized scratches can be addressed. Older cars may undergo full-car polishing depending on their condition. The key is regular waxing—it is recommended to wax once a month for cars parked outdoors or for those who are particularly meticulous about car care.

What are the battery specifications for Subaru vehicles?

Subaru Outback uses Q85R, and the start-stop battery is 90D23R. Battery principle: A battery is essentially a storage battery. During charging, external electrical energy is used to regenerate the active materials inside, storing electrical energy as chemical energy. When electrical energy needs to be released, the chemical energy is converted back into electrical energy for output. Precautions: When Outback owners inspect the battery and battery fluid level, if they find that the battery fluid level is below the lower limit or there is a leakage issue, they should promptly visit an authorized Subaru service center for inspection. Alternatively, owners can add distilled water to the upper limit themselves. If distilled water is not added, the positive and negative plates of the battery will be exposed to air. Prolonged exposure will cause oxidation with the air, affecting the battery's lifespan and capacity.

How many turns of the steering wheel are appropriate for a right-angle turn?

It is generally appropriate to turn the steering wheel two full turns for a right-angle turn. First, ensure the vehicle body is properly aligned before making the turn. If the body is tilted, you are likely to cross the boundary line during the turn, resulting in failure during the test. Regular practice is essential to recognize when the vehicle body is properly aligned. Here are some key points about right-angle turns: 1. Right-angle turns can be either left or right turns. For a left right-angle turn, steer slightly to the right (as turning right tends to bring the vehicle closer to the right boundary line, so it's advisable to stay slightly to the right). For a right right-angle turn, steer slightly to the left. 2. When the front of the vehicle (engine hood) reaches the corner, pay close attention to the right-side mirror to ensure it remains parallel with the boundary line.

What is the reason why the BYD Qin cannot switch to pure electric mode?

BYD Qin's inability to switch to pure electric mode may be due to low battery power or low voltage in individual battery cells of the battery pack, or faults in the battery sampling wires or collectors. Below is relevant information: 1. Introduction: EV mode is essentially pure electric drive. When the vehicle's battery power is insufficient, the vehicle will automatically start the engine to drive and simultaneously charge the battery. Once the vehicle's battery reaches a usable level, the engine will automatically shut off, and the vehicle will continue to operate in pure electric mode. 2. Advantages: EV mode offers three major advantages: environmental friendliness, energy efficiency, and simplicity, replacing traditional fuel engines and eliminating the need for a transmission during driving. In urban use, it can save fuel, and the engine does not produce any noise. Hybrid vehicles, compared to pure electric vehicles, have certain advantages, with extended range making vehicle use more convenient.

How Often Should Tires Be Replaced Normally?

Tires should be replaced every 3 years. If the vehicle is driven 20,000 kilometers a year, replacement can be considered in 2 to 3 years. If the annual mileage is around 10,000 kilometers, replacement should be considered in 4 to 5 years. Relevant information about car tires is as follows: 1. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures while driving. Therefore, they must have relatively high load-bearing performance, traction performance, and cushioning performance. 2. At the same time, they are also required to have relatively high wear resistance and flex resistance, as well as relatively low rolling resistance and heat generation. 3. According to their usage, tires can be divided into: passenger car tires, light truck tires, truck and bus tires, construction machinery tires, off-road vehicle tires, and agricultural and forestry machinery tires.
