Is It Normal for Car Wheels to Rust?

Wheel rust is certainly not normal. First, you need to confirm whether it's the wheel that's rusting or if it's the brake disc. Rust on the brake disc is normal. Reasons for Car Brake Disc Rust: Car brake discs are generally made of cast iron, so they will gradually rust when the vehicle is parked or stored for a period of time. This is normal and does not indicate a problem with the brake disc's quality. If the rust on the brake disc is minimal, no special treatment is needed because the slight rust will be removed by braking during driving. If the rust is more severe, it may cause vibrations or shaking during braking, such as brake pad vibration, steering wheel vibration or shaking, or body vibration. Severe rust is difficult to remove through braking, and even if the rust is removed, uneven thickness of the brake disc can cause braking vibrations. Therefore, it is necessary to perform maintenance on the brake disc every two months to prevent further rust development. Methods for Removing Rust from Wheels: Rinse the wheel's steel rim with clean water to wash away any dirt. Spray an appropriate amount of rust remover evenly onto the rust spots. Wait for a while, then use a sponge to repeatedly scrub the surface of the steel rim. The rust spots attached to it will disappear. Rinse with clean water to finish.

Does Overfilling Car Antifreeze Affect the Vehicle?

Overfilling with a reputable brand of antifreeze generally has no significant impact. The excess antifreeze will expand due to heat during vehicle operation and overflow through the pressure relief valve, leaving only minor stains. However, it is advisable to use a syringe to remove any antifreeze above the maximum fill line. In contrast, low-quality antifreeze produced by substandard manufacturers may be corrosive. Not only can it damage the cooling system, but the overflow of excess antifreeze may also harm electrical wiring and other components in the engine bay. In severe cases, it can corrode the radiator and leak into the engine. Vehicle antifreeze typically requires replacement every 2 years or 40,000 kilometers, though this is only a general guideline. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement schedule should be adjusted based on actual usage. Regularly check the antifreeze level and top it up promptly if low. If suspended particles, sediment, discoloration, or deterioration are observed, replace the antifreeze immediately and flush the system. Methods to determine if antifreeze is low: 1. Monitor the antifreeze warning light on the dashboard. If illuminated, it likely indicates low antifreeze, though it could also signal excessive engine temperature. 2. Inspect the antifreeze reservoir. If the level is below the minimum (MIN) mark, do not continue driving and refill promptly. 3. Check the level markings on the antifreeze overflow tank. The normal level should be between the MAX and MIN lines. If it falls below MIN, the antifreeze is insufficient.

How to Solve the Problem of Stuck Car Window?

Here are the solutions for the problem of stuck car window glass: 1. Clean the accumulated dust: The stuck window during lifting is caused by a large amount of dust in the rubber guide channel of the window. Simply wet a cloth with water and clean the dust. 2. Rubber aging: The aging of the window rubber may also cause the window to lift and lower unsmoothly. In this case, just use lubricating oil to deal with it. Spray it on the rubber, which can lubricate on one hand and maintain the toughness of the rubber on the other hand, reducing the occurrence of dry cracking. While solving the aging problem, it also plays a certain preventive role.

Do new cars come with a spare tire when purchased?

Most new cars come equipped with a spare tire, but some brands do not include one. Detailed information about spare tires is as follows: 1. A spare tire is an additional tire installed in a vehicle for emergency use. When a car tire encounters issues, the spare tire plays a crucial role by replacing the faulty tire, allowing the vehicle to continue driving safely. New cars typically come with a spare tire and the necessary tools. The spare tire is usually located in the trunk and there is only one. In case of a flat tire, the corresponding tools can be used to replace it. 2. Not all cars have a spare tire; some brands do not include one. For example, BMW and Mercedes-Benz vehicles—BMW's entire lineup and most Mercedes-Benz models—do not come with a spare tire. These cars use run-flat tires instead. Run-flat tires allow the car to continue driving at up to 80 km/h for a maximum of about 80 kilometers after a puncture, which is sufficient to reach the nearest repair shop or gas station for a tire replacement. Therefore, BMW and Mercedes-Benz do not provide spare tires. Additionally, the absence of a spare tire reduces the vehicle's weight, thereby improving handling. 3. Run-flat tires can continue to operate safely even after losing pressure. After a puncture, the thick sidewalls of run-flat tires provide strong support, preventing the vehicle from rolling over. Moreover, cars with run-flat tires do not need a spare tire, as they can continue driving after a puncture without requiring immediate replacement. This offers convenience and increases trunk space.

What are the consequences of not displaying the annual inspection sticker?

Failure to display the annual inspection sticker and other required decals will result in a fine and a deduction of one point. Below are the requirements for displaying vehicle annual inspection stickers: 1. Display location: According to Article 13 of the "Regulations for the Implementation of the Road Traffic Safety Law," the annual inspection compliance sticker, compulsory traffic insurance sticker, and green environmental protection sticker must be affixed to the upper right corner of the vehicle's front windshield. 2. Punching requirement for the inspection sticker: Punching the annual inspection sticker was an early method to identify the vehicle's inspection date. Along the edge of the upper part of the sticker, there are 1 to 12 punchable positions representing the 12 months. For example, if the inspection date is in June, a hole will be punched at the number 6.

What are the common lubrication methods for engines?

There are three common lubrication methods for engines: pressure lubrication, splash lubrication, and gravity lubrication. Pressure lubrication: Uses an oil pump to deliver lubricating oil under pressure to the friction surfaces of components, forming an oil film of sufficient thickness to withstand mechanical loads, ensuring reliable lubrication. This method primarily serves components with high relative speeds and significant mechanical loads in the engine. Splash lubrication: Utilizes oil droplets splashed by rotating components such as the crankshaft and camshaft during engine operation or sprayed from oil holes in the connecting rod big end to lubricate friction surfaces. This method is used for components like cylinder walls, cams, and piston pins. Periodic lubrication: Involves the regular application of grease for lubrication, primarily targeting components such as the generator, starter motor, and water pump bearings.
