Can 4S shops do maintenance on Sundays?

"4S shops can perform car maintenance on Sundays because they belong to the service industry, which has staff on duty during weekends and holidays, allowing for maintenance services. Car maintenance primarily involves routine upkeep aimed at keeping the vehicle clean, eliminating potential hazards, preventing component damage, and extending the car's lifespan. Routine car maintenance is divided into two types. One is minor maintenance, which includes changing the engine oil and oil filter, while major maintenance typically involves a comprehensive one-time service for the entire vehicle. Key maintenance items include oil changes, replacing the oil filter, air conditioning filter, spark plugs, and brake fluid. Minor car maintenance is usually performed every 5,000 kilometers, while major maintenance is typically done every 50,000 to 60,000 kilometers. Car maintenance may seem like a minor task, but it not only preserves the vehicle but also extends its lifespan, enhances safety performance, and ensures driver safety. Car maintenance basics: The engine oil change cycle is every 5,000 kilometers. Brake fluid levels should be checked and topped up regularly. Spark plugs should be inspected and replaced periodically. Normal spark plug insulation ceramics should remain in good condition. Tire pressure should be checked regularly and maintained at an appropriate level, neither too high nor too low. "

What does 108H mean for car tires?

Tire 108H refers to the load index of the tire, where H indicates a speed rating of 210 km/h. The speed rating denotes the maximum speed at which the tire can carry a specified load under defined conditions. The number 108 represents a load index of 1000 kg, which is the maximum load a single tire can bear, expressed as a code in kilograms. When replacing tires, it's essential to understand the load index, speed rating, and specifications of the car tires. Tires are typically mounted on metal rims, supporting the vehicle body, absorbing external shocks, ensuring contact with the road, and maintaining driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing capacity, traction, and shock absorption properties. When selecting a tire's load index, it's necessary to calculate based on 1.5 times the vehicle's total weight. For example, a load index of 100 corresponds to 800 kg. A typical passenger car has four tires, multiplying by four gives 3200 kg. Calculating at 1.5 times, four tires with a load index of 100 can support a vehicle weighing up to 2133 kg. The speed rating should be chosen based on actual conditions and the vehicle's performance parameters, and this index is independent of the number of tires.

Can a Car Purchased in the US Be Shipped Back to China?

It is possible to ship a car purchased in the US back to China, and there are four legal methods to do so. Four legal methods: 1. Travel to the foreign country yourself as a tourist or similar status to complete the car purchase process. This method is relatively difficult, as the buyer needs to have a thorough understanding of the local market and conditions. 2. Ask friends or relatives abroad to purchase the car on your behalf. This is the best option for buyers who have acquaintances overseas. 3. Entrust a proxy company abroad to handle the purchase. This is more suitable for those who are not very familiar with the foreign market. 4. The most convenient method is to hire a professional buyer in China or directly place an order with a bonded zone trading company. This eliminates the subsequent steps of finding a shipping company and entrusting an agency to handle customs clearance procedures, allowing you to simply wait at home for the car to arrive at the port. However, the discounts available through this method are limited. Important considerations when purchasing a car abroad: The vehicle should preferably be sourced from Canada or the US, or be your own car. It is recommended that the car be a used vehicle that is at least 3 years old with a mileage of over 40,000 kilometers.
