How to drive to the Taiyuan internet-famous bridge?

Search for Jinxi Traffic Police Training Base as the destination on the map. Once arrived, continue driving up the mountain along the brand-new main road. The internet-famous bridge refers to the viaduct, which has gained popularity due to its three-tiered bridge structure, serving as the main body of the new Taiyuan Tianlong Mountain Tourist Highway. You can drive there yourself using car navigation to reach the internet-famous bridge. Additionally, please note that random parking is prohibited when visiting the bridge. The traffic police department will deploy specialized officers, establish a "task force", organize dedicated night patrol teams for enforcement, and implement measures combining fixed-point and mobile operations. Illegal activities will be penalized through methods such as turning vehicles away, on-site fines, ticketing with photo evidence, street-sweeping vehicle recordings, and compulsory towing.

Is Engine Maintenance Necessary?

It is necessary. The wiring of a car engine requires maintenance; neglecting it can accelerate wire aging or increase the risk of short circuits. Wire harness aging: Common engine wire harnesses are typically composed of multiple strands of copper wires, wrapped externally with plastic. During daily driving, the engine compartment temperature can become very high. The plastic coating on the wire harness releases plasticizers and other chemicals when heated, which react with the copper wires inside, reducing the plastic's strength and increasing the resistance of the copper wires. This ultimately raises the risk of short circuits due to wire harness aging. The rubber hoses in the engine compartment are made of unsaturated hydrocarbon polymers, which are prone to oxidation as they age, potentially leading to vehicle self-ignition. Extending service life: Over time, issues such as aging, oil contamination, moisture, oxidation, and short circuits can arise. These problems significantly affect the engine's performance and efficiency, leading to abnormal vibrations, increased noise, reduced power, and decreased fuel economy. Such issues can drastically shorten the vehicle's lifespan. Therefore, both the engine and electrical circuits of older vehicles require regular maintenance to extend their service life as much as possible.

Can Elderly Mobility Scooters Be Driven on Public Roads?

There are no specific regulations prohibiting elderly mobility scooters from being driven on public roads. Here are the relevant details: 1. Traffic Management Authorities: Traffic management authorities classify elderly mobility scooters as motor vehicles, requiring drivers to hold a valid license. Manufacturers must meet safety standards for the scooters to be registered and insured. 2. Compliance with Traffic Laws: When driving a mobility scooter, it is essential to obey traffic laws, avoid running red lights, driving in the wrong direction, or speeding to prevent accidents. Ensuring the safety of oneself and others is paramount. Some elderly mobility scooter drivers have weak traffic safety awareness and poor driving skills, often engaging in illegal behaviors such as running red lights, driving in the wrong direction, cutting lanes, and weaving through traffic. This significantly increases the probability of traffic accidents, posing substantial safety hazards on the roads. Consequently, traffic management authorities across various regions have intensified strict supervision of elderly mobility scooters.

Will Small Scratches on the Car Body That Expose the Primer Rust?

Generally, any scratch on a car has the potential to rust, and if the primer is damaged, the likelihood and speed of rusting will increase further. Here is some additional information: 1. Car paint typically consists of four layers, from the inside out: the electrophoretic layer (primer), the middle coat, the color coat, and the clear coat. The so-called "primer" is actually a protective film applied to the metal body through an electrophoretic chemical process, primarily to enhance the body's corrosion resistance. Typically, white cars have black or gray primer, while dark-colored cars have the opposite. 2. The middle coat is sandwiched between the primer and the color coat, serving to bond them together, ensuring the color coat adheres more uniformly and firmly to the surface, enhancing the paint's fullness. The color coat is the layer that gives the car its visible color. The clear coat is transparent and colorless, serving to increase the paint's glossiness and protect the color coat from scratches. There are two types of color coat processes: 1k and 2k. The 2k process includes a built-in protective layer, eliminating the need for a clear coat.

Where to Add Coolant in a Volvo?

On the left side of the engine compartment, there is a plastic reservoir where the red antifreeze is located. To add antifreeze, simply open the plastic cap. It serves two main functions: first, to prevent freezing, and second, to cool. Antifreeze prevents the coolant from freezing and cracking the vehicle's cooling system when parked in cold winter conditions, while in summer, it prevents overheating. There are two ways to check the antifreeze: 1. Check the fluid level: This can generally be done by the owner themselves. You can take a moment during car washing to check the antifreeze reservoir; the fluid level should be between MAX and MIN. The antifreeze should not be too low, nor should it be too high. Generally, vehicles rarely experience a shortage of antifreeze, so there's usually no need to worry too much. 2. Check the antifreeze's freezing point: This requires specialized equipment. Most owners cannot do this themselves and should visit a professional repair shop for inspection. The method to check the antifreeze's freezing point: Test the density by inserting a specialized tool into the antifreeze reservoir, and determine the freezing point based on the density.

Why Does a Car Make Strange Noises After Passing Through a Puddle?

There are many reasons why a car may produce noises after driving through water, mainly including water ingress in the brake pads, foreign objects trapped between the brake pads and calipers, water ingestion in the exhaust pipe, or debris lodged in the chassis. Below is a detailed explanation of the causes of noises after a car drives through water: 1. Water in the brake pads: If the car passes through shallow water and water splashes onto the brake pads, a squealing noise when braking is normal. In this case, simply continue driving normally until the water on the brake pads dries up. 2. Foreign objects on the brake pads: If the car passes through deeper water, foreign objects such as plastic bags, paper, or mud may get trapped on the brake pads, causing noise when braking. In this situation, the brake pads should be cleaned. 3. Water ingestion in the exhaust pipe: If the car passes through deep water and water enters the engine through the exhaust pipe, it can prevent the proper combustion of fuel and air mixture, leading to noise. In this case, the car should be moved out immediately, and the engine should be cleaned. Failure to do so may result in engine damage or even complete failure. If the car stalls in the water, do not attempt to restart it; instead, call a tow truck to avoid further damage to the engine. 4. Debris in the chassis: If foreign objects get lodged in the chassis after driving through water, it can also cause noise while driving. In this case, the chassis should be cleaned thoroughly.
