Can the Headlight Cover Be Replaced Separately?

The headlight cover cannot be replaced separately. Reasons why it cannot be replaced separately: Generally, individual headlight covers are not available for purchase; replacing them requires replacing the entire headlight assembly. Additionally, replacing just the outer lens may result in poor sealing, leading to water ingress inside the headlight, which can affect the internal wiring harness. While standalone headlight covers are not sold, some car modification shops may offer headlight customization if they have access to used headlights. However, this option is not widely available, and the cost may not be low. For non-luxury vehicles (such as Mercedes-Benz or BMW), replacing the entire assembly is often more practical. Material of headlight covers: Typically, the glass covers of front headlights and taillights are made from high-grade polycarbonate (also known as PC, the same material used for resin eyeglass lenses) through injection molding. Polycarbonate is known for its high hardness, strength, toughness, UV resistance, and excellent light transmission. As a result, these covers maintain their color and clarity even after prolonged use.

How to Charge a Car Key?

Car keys typically use small batteries that generally cannot be recharged. Instead, the battery should be replaced directly. You can have it replaced at a 4S store or do it yourself. If the key uses a coin cell battery, the owner can replace it at an after-sales service point or purchase a battery with the same specifications online and follow the key's manual to replace it. Emergency solutions for a dead car key battery are as follows: 1. First, remove the mechanical key from the smart key, use it to open the car door, then press the side of the key with the logo against the ignition button to start the vehicle. Finally, remember to replace the smart key's battery. 2. The battery life of a smart key varies depending on usage, but it generally lasts around 2 years. Therefore, car owners should develop good habits and replace the smart key battery regularly. 3. Typically, a smart key losing power is a gradual process. Before it completely fails to unlock the door, the smart key may start malfunctioning. At this point, owners should promptly replace the battery.

Does Interior Color Change Affect Vehicle Inspection?

Interior color change does not affect vehicle inspection, but changing the exterior color of the car requires filing and registration with the vehicle management office. The items inspected during annual inspection include: 1. Checking whether the engine, chassis, body, and their accessories are clean, complete, and functional, whether the paint surface is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records; 2. Verifying whether the vehicle's braking performance, lighting, exhaust, and other safety features comply with relevant regulations. Circumstances that disqualify a vehicle from inspection include: 1. Discrepancies between the vehicle's condition and the records on the driving license or archives; 2. Damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; 3. Vehicle modifications, alterations, or technical transformations without undergoing approval and change procedures; 4. Failure to spray the unit name and enlarged license plate characters as required; 5. Improper installation of alarms or signal lamps.

Why is the coolant level low?

There are several reasons for coolant loss, including natural consumption, coolant leakage, or coolant entering the combustion chamber to participate in combustion, such as cylinder block cracks, cylinder head gasket burning or corrosion deformation, etc. Natural consumption: Various fluids in a car inevitably experience consumption. Since coolant is responsible for cooling the car engine and is often in a high-temperature state, it is normal for coolant to lose about 10%-36% in a year under normal circumstances. Coolant leakage: If the coolant needs frequent replenishment, it indicates there is a leakage. Rubber-metal pipes and fittings, often exposed to high temperatures, may age due to thermal expansion and contraction, leading to tiny gaps through which coolant can seep. Common leakage-prone areas include the radiator hoses, air conditioning heater hoses, thermostat, and water pump seals. Regularly inspecting sealing glue, tightening clamps, and timely maintenance can ensure driving safety and prevent breakdowns or accidents. Coolant entering the combustion chamber to participate in combustion, such as cylinder block cracks, cylinder head gasket burning or corrosion deformation, etc.: In this case, you can check the oil dipstick to see if the engine oil has emulsified (oil emulsification means the oil turns into a milky liquid, appearing milky white or milky yellow, resembling stirred flour paste with bubbles). This happens because the cylinder block has oil and water passages. Once the cylinder head gasket is damaged, the water passage cannot be sealed, allowing coolant to flow into the oil passage. The solution is to replace the cylinder head gasket.

What is the engine model of Borgward?

Borgward uses a self-developed engine, equipped with a 1.8T turbocharged direct injection engine. Its highlights include a lightweight body, featuring high performance, high comfort, low fuel consumption, and low emissions. This engine employs direct injection technology and lightweight mechanical control turbocharging, delivering an impressive torque of 280 N·m at a low speed of 1,750 rpm, showcasing excellent performance. Below is relevant information: 1. The turbocharged direct injection engine allows fuel to be injected directly into the cylinder via a high-pressure injector. Due to the piston top's recessed bowl-shaped design, the fuel forms a spiral mixture in the cylinder. This type of engine is also widely recognized as the best diesel engine currently available. 2. The engine is the heart of a car, and engine oil is the heart of the engine. Therefore, during regular car maintenance, it is essential to change the engine oil periodically to protect the engine. The engine radiator often suffers from rust and scaling, which reduces its cooling efficiency and causes the engine to overheat. Thus, it is necessary to regularly clean the rust and deposits from the engine radiator to maintain its cleanliness.

How to repair car paint chipped by stones?

There are mainly the following methods for paint repair: 1. Generally, the front bumper, rear bumper, and fuel tank cover of a car are made of plastic, and the paint surface is relatively thin. If it gets scratched and you don't want to repair it, you can purchase a touch-up pen for treatment. 2. If the damage is on other parts of the vehicle, such as the door panel, then it depends on the type of paint. If it is a solid color paint, a touch-up pen can also be used for treatment, and it usually won't be noticeable under normal circumstances. 3. If it is metallic paint or pearlescent paint, it will look very obvious. In this case, you need to go to a 4S shop for spray painting. And 4S shops usually perform spray painting on the entire panel.
