What to Do When the Car Dashboard Becomes Sticky Due to Aging?

Can a Car Still Be Driven After Being Flooded?

If a vehicle has been flooded, it is recommended not to drive or use it. Here is extended information about the hazards of flood-damaged cars: 1. Electronic Control Systems Inside the Car: Rainwater mixed with contaminants is highly corrosive and can affect the functionality of electrical components, especially in the long term. Most cars are equipped with electronic control systems (e.g., engine ECU, ABS system, SRS system, GPS navigation, etc.). If these systems are exposed to water, it can cause short circuits in the ECU's internal IC circuit board and rust on connector terminals, gradually leading to corrosion of metal parts. This can result in poor contact or even short circuits and burnout in the circuits. 2. Engine: The connecting rod in the engine may deform, shortening the piston stroke and preventing proper compression of gases. Piston rings may lose elasticity or fail to seal, causing gas leakage. Compressed gases may escape into the crankcase. Intake and exhaust valves may not seal properly when closed, leading to compressed gas leakage into the intake and exhaust manifolds.

What is the Maintenance Reminder Light?

Maintenance reminder light indicates when a wrench symbol appears on the car's dashboard. Here is relevant information about the maintenance reminder light: 1. Introduction to the maintenance reminder light: The "SERVICE" symbol on the car's dashboard display is a maintenance cycle indicator. When the ignition switch is in the ON position, the "SERVICE" symbol on the display flashes, and the symbol disappears after starting the engine, indicating that the vehicle requires maintenance. 2. Items of car maintenance: Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

What Causes the Abnormal Noise from the Right Front Wheel of a Car?

There are many reasons for abnormal noise from the right front wheel of a car. The following is a detailed analysis and solution: 1. Severe wear of brake pads: When the thickness of the car's brake pads wears below 5mm, the braking force will significantly decrease, and symptoms such as abnormal noise during turns may occur. In this case, the brake pads should be replaced promptly. 2. Damage to the right front wheel shock absorber: If the shock absorber of the right front wheel is damaged, it can also cause abnormal noise. The car should be lifted for a detailed inspection in this situation. 3. Deformation of the right front wheel hub: Deformation of the right front wheel hub can cause abnormal noise while driving. For safety reasons, it is best to replace the hub. 4. Wear of the right front wheel tire: Excessive wear of the right front wheel tire or punctures from nails, stones, etc., can also lead to abnormal noise. In such cases, further inspection at a repair shop is necessary.

How to Distinguish Between China 5 and China 6 Vehicles?

To distinguish between China 5 and China 6 vehicles, look at the emission standard letters on the rear of the car. China 5 is represented by 'V,' while China 6 is represented by 'VI.' The differences between the two are as follows: Different Emission Standards: China 6 emission standards are more than 30% stricter than China 5. Under the exclusion of working conditions and testing influences, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different Implementation Times: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth phase of national motor vehicle emission standards. The China 6 standard was implemented on July 1, 2019. Different Principles: Under the China 5 standard, diesel and gasoline vehicles had different emission standards. However, China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different Issuing Authorities: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different Letter Representations: China 5 is represented by 'V,' while China 6 is represented by 'VI.' Different Monitoring Requirements for Plug-in Hybrid Electric Vehicles (PHEVs): Compared to China 5, China 6 has improved monitoring requirements for PHEVs, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulatory aspects. China 5 Standard Limits: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b. Details are as follows: China 6a Standard Limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6b Standard Limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM (particulate matter) per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted in normal use (no driving or license plate restrictions), their resale value will be significantly impacted. For truck owners, if they purchase a truck on loan for cargo transport, after paying off the loan, the vehicle's depreciation equates to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, with their longer service life and greater road rights, offer more advantages.

What maintenance items are required at 20,000 kilometers?

Replace engine oil and three filters, replace spark plugs, and clean the throttle body. Here is some extended information about car maintenance: 1. Definition: Car maintenance, also known as vehicle servicing, refers to the regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts as a preventive measure. 2. Includes: Car maintenance mainly includes the servicing of the engine system, transmission system, air conditioning system, etc., with the aim of maintaining a clean vehicle appearance, normal technical conditions, eliminating potential hazards, preventing faults, and extending the service life.

Can I drive on the highway with a driver's license less than one year old?

Drivers with a license less than one year old are not allowed to drive on the highway. During practice, a driver with more than three years of experience must accompany them in the passenger seat. Here are some precautions for new drivers on the highway: 1. Do not change lanes in tunnels: Visibility is poor in tunnels, and the eyes need time to adjust. Additionally, tunnels often have many curves, making lane changes highly prone to traffic accidents, which are difficult to rescue from once they occur. 2. Pay attention to road signs, markings, and warning signs: Be mindful of road signs, markings, and warning signs, as well as strict speed limits. 3. Stay away from large trucks: New drivers should maintain a safe distance when encountering large trucks.
