For maintenance and repairs, it is advisable to choose a 4S shop as it offers better after-sales service. For vehicles out of warranty, maintenance can be done outside at a lower cost. However, it is recommended to replace transmission oil, differential oil, and fuel filters at a 4S shop for better assurance. Advantages and disadvantages of 4S shops and repair shops: 1. 4S shops: They are more professional and can provide comprehensive solutions, but there may be cases where a small faulty part leads to the replacement of the entire component. 2. Repair shops: They are cheaper and more experienced in handling minor issues. They often specialize in certain car models, ensuring a certain level of professionalism and offering solutions that are relatively official. However, their skill levels vary, and they may lack the expertise and professional equipment for certain car models, resulting in poor after-sales service.

I've been driving for over a decade and always felt that 4S shop maintenance is reliable but too expensive. For my old clunker, an oil and filter change at the neighborhood auto repair shop costs just 300 yuan, while the 4S shop charges double. But let me remind you, for anything involving the engine or transmission, it's better to go to the 4S shop—they have all the computer equipment and can read model-specific fault codes. Last time I got a timing belt replaced outside, the mechanic almost damaged a sensor, which would have been more trouble than it's worth.

Why Does the Brake Pad Smell Burnt During Continuous Downhill Driving?

Here is the relevant introduction to why the brake pad smells burnt during continuous downhill driving: 1. High Resistance: Because the brake pad is subjected to greater resistance than usual during downhill driving, it is prone to damage, carbonization, and significant wear. When the brake pad ages, it can easily wear out the carbon lining completely, leaving only metal-to-metal friction. It's important to note that metal-to-metal friction is minimal, which can lead to slipping and brake failure. 2. Vaporization Phenomenon: Additionally, high temperatures can cause the brake fluid to vaporize, which is intended to expel air from the brake lines. During brake adjustment, bleeding the brake lines to remove air is also a crucial step. Another reason is that prolonged downhill braking causes the brake pad temperature to rise rapidly, leading to high-temperature deformation and reduced contact area, which can also result in brake failure.

Is it serious if fully synthetic oil has run for 12,000 kilometers?

Fully synthetic oil that has run for 12,000 kilometers needs to be replaced promptly. Generally speaking, the service life of fully synthetic oil is around 10,000 kilometers. If the vehicle is in good operating condition, running it for 12,000 kilometers is acceptable, but it is recommended that the owner replace the oil in a timely manner. Below is relevant information about automotive engine oil: 1. Types: There are three types of engine oil used in vehicles, namely mineral oil, semi-synthetic oil, and fully synthetic oil. Compared to mineral oil and semi-synthetic oil, fully synthetic oil has a more stable molecular structure, uniform molecular size, and offers excellent lubrication and oxidation resistance. 2. Functions: The primary role of engine oil is lubrication, reducing the friction coefficient between internal engine components during operation. It also repairs minor damage caused by friction and carries away metal particles generated by the friction between components.

What are the impacts of a damaged car crash beam on the vehicle?

The primary function of a crash beam is to provide a certain level of protection for the vehicle during low-speed collisions, acting as a buffer to reduce the extent of vehicle damage. In other words, the main role of the crash beam is to prevent vehicle damage, and it has limited effect on improving the safety of occupants inside the car. A damaged car crash beam should be replaced promptly. Below is an introduction to car crash beams: 1. Front bumper crash beam: During low-speed collisions such as rear-end accidents on urban roads, the front bumper crash beam plays a role in protecting components like the fenders, radiator, hood, and lights. 2. Rear bumper crash beam: The rear bumper crash beam helps reduce damage to areas such as the trunk, tailgate, and rear light assemblies.

Where is the fuel pump relay of Wuling Zhiguang?

The fuel pump relay of Wuling Zhiguang is located in the fuse box under the instrument panel. The following is an introduction to the principle and structure of the fuel pump relay: Working principle of the fuel pump relay: When the fuel pump relay is working, the electromagnet is energized to pull the armature down, making D and E contact and closing the working circuit. When the electromagnet is de-energized, it loses its magnetism, and the spring pulls the armature up to cut off the working circuit. The relay is a switch that uses an electromagnet to control the on and off of the working circuit. Structure of the fuel pump relay: Electromagnetic relays generally consist of an iron core, a coil, an armature, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, generating an electromagnetic effect, which drives the moving contact of the armature to close with the static contact.
