Can a Flood-Damaged Car Drive on Highways After Repair?

Flood-damaged cars can be driven on highways after repair, but it is not recommended. Here is relevant information: 1. Hazards: For flood-damaged cars, rainwater has caused severe damage, and even after repair, the car cannot fully return to its original condition. There are still risks of unknown faults inside the vehicle. Water entering the engine can cause damage, leading to unexpected stalling during driving; transmission failure can cause the vehicle to slip or shake, resulting in accidents; electrical circuit faults can lead to short circuits and fires. 2. Precautions: If a water-damaged vehicle has been repaired, it can be used. However, during the repair process, it is essential to ensure all necessary repairs are completed. All water-damaged parts should be either replaced or repaired based on their specific conditions. Electrical system connectors and wiring should be thoroughly dried and rust-proofed. Check all vehicle fluids for water contamination—if any moisture is present, they must be replaced.

What is the Difference Between Filing an Insurance Claim and Settling Privately?

Here are the differences between filing an insurance claim and settling privately: 1. Protection: Filing an insurance claim can serve as proof; private settlements offer no protection. 2. Convenience: Filing an insurance claim is time-consuming and labor-intensive, while private settlements can reduce complexity. Below is additional information on what to do if your car is scratched and the culprit cannot be found: 1. Check for cameras: Look around for surveillance cameras to identify the person who scratched your car. 2. Check the dashcam: If your car has a dashcam, review the footage to identify the culprit. 3. Seek compensation from the service area: If your car does not have a dashcam, check if the parking service area can provide compensation. 4. File an insurance claim: If the service area cannot provide compensation, report the incident to your insurance company. If you have insurance, you may receive some compensation.

Is It Harmful for a Car to Be Exposed to the Sun?

Exposing a car to the sun for extended periods can have negative effects. Below is relevant information about car maintenance: 1. First Maintenance: Some manufacturers determine the first maintenance schedule based on time or mileage. The exact timing should be referred to in the vehicle's user manual or warranty manual. The first maintenance is crucial and usually free, so it's important not to miss it, as doing so could affect the vehicle's three-year warranty. 2. Maintenance Items: Key car maintenance items include replacing engine oil, oil filters, transmission fluid, spark plugs, cabin air filters, engine air filters, and brake fluid. However, not all items need replacement in every maintenance session; this depends on their service life. Additionally, maintenance involves inspecting and servicing dozens of components across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.

Is Automotive Antifreeze Conductive?

Automotive antifreeze is conductive. The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances, which give it conductive properties. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. Antifreeze replacement cycle: For vehicles that operate for extended periods, such as taxis, high-quality antifreeze should generally be replaced annually. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned. Can different antifreeze brands be mixed? It is essential to use antifreeze from the same brand. Different brands may have varying production formulations, and mixing them could lead to chemical reactions between additives, rendering them ineffective.

Can You Turn on the Air Conditioning When Driving Through Water?

It is best not to turn on the air conditioning when driving through water, as it may cause water to enter the throttle valve. It is recommended to check the throttle valve. If the car shakes when the air conditioning is turned on, it is clearly due to insufficient air-fuel mixture, resulting in insufficient power, and the engine cannot drive the compressor and electric fan. Below is relevant information: 1. Maximum Wading Depth: The maximum wading depth is the distance between the tire contact point and the engine intake port, known as Wattiefe in English. The maximum wading depth refers to the maximum depth that can be safely traversed under safe driving conditions, also known as the safe depth. It is also an important indicator for evaluating a vehicle's off-road capability. The greater the maximum wading depth, the stronger the vehicle's water-crossing ability. 2. Impact: If the intake port is below the water level during wading, water may be sucked into the engine cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical structure. Therefore, the wading depth must not exceed the height of the engine intake port. Installing a snorkel can also increase the height of the engine intake port, thereby improving the maximum wading depth.

What Causes Knocking Sounds When the Fuel Injector is Faulty?

The reasons for knocking sounds when the fuel injector is faulty are as follows: If it is a diesel electronic fuel injector, it could be due to excessive single-cylinder fuel injection or advanced fuel injection timing. It is recommended to calibrate the pre-injection volume and mid-speed fuel quantity (emission point) for both old and new injectors. A significant deviation in idle fuel quantity can also cause knocking. Additional relevant information is as follows: 1. Cleaning: Fuel injectors should generally be cleaned every 2 years or every 50,000 to 80,000 kilometers, depending on the quality of gasoline in the vehicle's usage area. The cleaning methods for fuel injectors are: non-dismantling cleaning; dismantling cleaning. 2. Note: Cleaning the engine fuel injector is essential, as the performance of the injector fundamentally affects the power output of each engine. Poor fuel quality can lead to injector malfunction, causing severe carbon buildup in the cylinder, accelerated wear of the cylinder liner and piston rings, unstable idle, increased fuel consumption, weak acceleration, difficulty starting, and excessive emissions. In severe cases, the injector may become completely clogged, damaging the engine.
