Can Corroded Car Glass Be Repaired?

If the corrosion area on the car glass is small, it can be repaired at an auto beauty shop. If the corrosion area is large, replacement is necessary. Precautions for replacing car glass: Generally speaking, depending on the quality of the adhesive and seasonal factors, the glass adhesive usually takes one to three days to fully cure. During this period when it is not completely cured, although you can drive, extra caution is required. Classification of car glass: Car glass is mainly divided into the following three types: laminated glass, tempered glass, and zoned tempered glass, which can withstand strong impacts. Car glass is categorized by its location into four types: windshield, side window glass, rear windshield, and sunroof glass.

What Are the Causes of Odors in Car Air Conditioning? How to Eliminate Them?

Odors in the air conditioning system can be caused by mold growth due to humid climates or lack of timely cleaning. Regular cleaning and disinfection of the air conditioning system can help eliminate these odors. Here are the main areas where odors commonly originate in the air conditioning system: Odors from the air conditioning filter: The air conditioning filter is responsible for filtering the air that enters the car cabin. Over time, it can accumulate a significant amount of dust and debris. Odors from the air conditioning evaporator: The evaporator, shaped like thick aluminum fins, can also collect dust. After using the air conditioning, the evaporator, which is where hot and cold air exchange occurs, can accumulate moisture from condensation. This moisture can lead to mold growth and musty odors. Odors from the air conditioning ducts: The air conditioning ducts are another area where dust can accumulate. The cold air flowing through the ducts can cause condensation, leading to moisture buildup, mold growth, and musty smells. Odors from the interior padding near the air conditioning drain: Condensation from the air conditioning system is typically drained through the air conditioning drain pipe. If the drain pipe becomes clogged, moisture cannot be properly drained, potentially contaminating nearby interior components such as floor mats, leading to mold growth and musty odors.

How long will the battery last if the brake lights are on?

If the brake lights are left on overnight, the battery will be drained. Below is a detailed introduction to car lights: 1. Signal lights: These include turn signals (hazard lights) and brake lights. Proper use of signal lights is crucial for safe driving. 2. Turn signals: These are activated when the vehicle is turning and flash intermittently to alert vehicles and pedestrians in front, behind, and to the sides. 3. Brake lights: These are very bright and are used to inform the following vehicle that the front vehicle is slowing down or stopping. Improper use of these lights can easily lead to rear-end collisions. 4. Night driving lights and width markers: Driving lights, commonly known as headlights, should be used appropriately by switching to low beams when meeting another vehicle and promptly switching back to high beams afterward to extend visibility and compensate for reduced visibility during the encounter. Changing between high and low beams should be used to signal when passing through intersections or overtaking. Width markers, commonly known as parking lights, are used at night to display the width and length of the vehicle.

Do New Cars Need Undercoating?

Choose undercoating based on the owner's needs. If you frequently drive on special road sections, it is recommended to install it. Undercoating is a high-tech adhesive rubber asphalt coating that can be sprayed on parts of the car such as the chassis, fuel tank, and underbody panels. These parts are exposed to the air and prone to damage. Undercoating can quickly form an elastic protective layer, providing excellent protection for the car chassis. Advantages of undercoating: 1. Corrosion prevention: The car chassis is exposed during daily use and prone to rust. When driving in humid environments or after washing the car, residual water on the chassis can corrode it over time, leading to rust. Undercoating helps prevent corrosion of the car chassis. 2. Stone chip protection: While driving, small stones can be kicked up by the tires. At high speeds, these stones can cause significant damage to the chassis. Undercoating reduces the impact of these stones, protecting the chassis from being punctured and aiding in its maintenance. 3. Vibration reduction: The car's engine, wheels, and other components are fixed to the chassis, often vibrating at the same frequency, which can reduce comfort. Undercoating helps dampen these vibrations, improving ride comfort. 4. Heat insulation and fuel efficiency: In summer, high ground temperatures can lead to excessive heat inside the car. Undercoating blocks some of this heat, preventing discomfort caused by high surface temperatures and reducing the strain on the car's air conditioning system. By blocking heat transfer and shortening cooling time, undercoating contributes to fuel efficiency. 5. Noise reduction: At high speeds, tire noise and other noises can become noticeable. Undercoating effectively reduces interior noise, providing a more comfortable driving environment.

What maintenance items are included in a 30,000-kilometer major service?

For a 30,000-kilometer vehicle maintenance, the service items include oil change, oil filter replacement, air filter replacement, fuel filter replacement, throttle body cleaning, spark plug replacement, etc. Below is a detailed introduction: 1. Engine oil and four filters: The four filters in engine oil maintenance include: oil filter, air filter, fuel filter, and cabin air filter. We know that the oil filter needs to be replaced every maintenance, while the air filter is recommended to be replaced every 10,000–15,000 kilometers, and the fuel filter is recommended to be replaced every 30,000 kilometers. The cabin air filter is recommended to be replaced every six months. 2. Throttle body cleaning: Throttle body cleaning is not necessary before 30,000 kilometers. After prolonged intake, the throttle body accumulates a lot of carbon deposits at the throttle opening, leading to reduced airflow. The vehicle may exhibit slight idle instability, idle vibration, and poor acceleration, indirectly increasing fuel consumption. At this point, we should inspect components like the throttle body and spark plugs that may cause these issues. 3. Spark plugs: Spark plugs should be replaced at 30,000 kilometers. Although spark plugs at 30,000 kilometers have not completely lost their ignition performance, their ignition capability has significantly degraded. Reduced ignition performance directly affects idle vibration, cylinder misfires, and poor acceleration. The decline in ignition performance increases engine load, which is also a factor affecting fuel consumption. 4. Air conditioning cleaning: Air conditioning cleaning removes dust and dirt from the AC ducts and provides a sterilizing effect. This service is optional.

What are the systems that make up the chassis?

The chassis consists of four major systems: the transmission system, steering system, braking system, and running gear system. Here is a detailed introduction to the four major systems of an automobile chassis: Transmission System: The function of the transmission system is to transmit the engine's power to the driving wheels. The composition of the chassis varies slightly depending on the type of vehicle. For example, in trucks and some sedans, the chassis typically includes the clutch, manual transmission, universal drive assembly, and drive axle. However, modern sedans increasingly use automatic transmissions, where the chassis consists of the automatic transmission, universal drive assembly, and drive axle—replacing the clutch and manual transmission. For off-road vehicles (including SUVs, or sport utility vehicles), the chassis also includes a transfer case. Running Gear System: The function of the running gear system is to support and install various automotive components and assemblies, transmit and withstand loads from both inside and outside the vehicle, ensuring normal operation. It mainly consists of the frame (or body), axles, suspension, and wheels. Steering System: The function of the steering system is to ensure the vehicle can move in the direction selected by the driver. It primarily includes the steering control mechanism, steering gear, and steering linkage. Modern vehicles commonly use power steering systems. Braking System: The function of the braking system is to decelerate the vehicle, bring it to a stop, and ensure reliable parking. The automotive braking system generally includes two independent systems: the service braking system and the parking braking system. Each braking system consists of brakes and braking transmission mechanisms. Modern vehicles' service braking systems are typically equipped with an anti-lock braking system (ABS).
