What Causes the Boiling Water Sound When Starting the Engine?

Because the engine experiences a significant jolt at the moment of starting, impact sounds may occur in areas with excessively small gaps. Adjusting the deformed gaps can eliminate these abnormal noises. The boiling water sound from the engine is considered an abnormal noise and requires repair. Engine abnormal noises can generally be categorized into: Abnormal noises during cold starts, abnormal noises during rapid acceleration, and abnormal noises during idle. Abnormal noises caused by aging or loosening of the engine mounts. Engine mounts, also known as rubber mounts or engine brackets, are typically installed between the engine and the vehicle body, connecting the two and securing the engine in place. Their most important function is to provide cushioning and vibration damping. Once the engine mounts age or become loose, engine vibrations will intensify. During maintenance, the following aspects should be noted: If components such as the fuel filter, oil filter, air filter, hydraulic oil filter, and various filter screens become excessively dirty, the filtering efficiency will decrease, allowing more impurities to enter the oil passages and cylinders, accelerating wear on mechanical parts and increasing the likelihood of faults. Severe clogging can also prevent the vehicle from operating normally. Excessive piston temperatures in the engine can lead to overheating, melting, and cylinder seizure. Overheating of rubber seals, V-belts, tires, and other components can cause premature aging, reduced performance, and shortened lifespan. Overheating of coils in electrical equipment such as starters, generators, and regulators can easily lead to burnout and scrapping. Vehicle bearings should be kept at an appropriate temperature; overheating will cause the lubricant to deteriorate quickly, ultimately leading to bearing failure and vehicle damage.

Is it unnecessary to purchase auto damage insurance after several years?

Whether it is necessary to purchase auto damage insurance depends on the model of the vehicle and the financial situation of the owner. Below are the relevant details: Age limit: Private vehicles older than 8 years are generally not covered. Although it is possible to purchase auto damage insurance for vehicles over 10 years old, the coverage amount will be very low due to significant depreciation. Few insurance companies are willing to cover vehicles over 10 years old, and compensation is provided on a proportional basis. Definition of auto damage insurance: Auto damage insurance refers to the compensation provided by the insurance company within a reasonable range when the insured or an authorized driver causes damage to the insured vehicle during an accident. Coverage scope: This insurance does not cover theft, robbery, standalone glass breakage, standalone wheel damage, etc. Therefore, not all vehicle damages will be compensated by the insurance company after an accident.

Is it okay to register after car modification?

It is okay to register after car modification. Here is the extended information: Relevant regulations: According to Article 10 of the "Regulations on the Registration of Motor Vehicles", if a registered motor vehicle has one of the following circumstances, the owner of the motor vehicle shall apply to the vehicle management office at the place of registration for modification registration: changing the body color, replacing the engine, replacing the body or frame, replacing the entire vehicle due to quality issues, changing the use nature from commercial to non-commercial or vice versa, or the owner's residence moving out of or into the jurisdiction of the vehicle management office. Car modification: The new "Road Traffic Safety Law" clearly stipulates that no unit or individual may assemble a motor vehicle or arbitrarily change the registered structure, construction, or characteristics of a motor vehicle. The structure of the vehicle includes the body color, length, width, height (four rigid standards), and the relevant technical parameters of the engine.

Can a completely flooded car be directly scrapped?

A car that has been flooded may not necessarily be scrapped; it depends on whether the flooded vehicle meets the national mandatory scrapping standards. Whether the car meets the scrapping standards is primarily determined by an insurance company's assessor, who evaluates the extent of the flooding and the damage to the vehicle's components. If the car does not meet the scrapping standards, it can either be repaired or sold directly. According to Article 4 of the "Regulations on the Mandatory Scrapping Standards for Motor Vehicles," registered motor vehicles that fall under any of the following circumstances shall be mandatorily scrapped. The owner must sell the vehicle to a motor vehicle recycling and dismantling enterprise, which will handle the registration, dismantling, and destruction in accordance with regulations and submit the vehicle's registration certificate, license plate, and driving license to the traffic management department of the public security authority for cancellation: (1) The vehicle has reached the prescribed service life as stipulated in Article 5; (2) After repair and adjustment, the vehicle still fails to meet the national safety technical standards for in-use motor vehicles; (3) After repair, adjustment, or the adoption of control technology, the vehicle's emissions or noise still fail to meet the national standards for in-use motor vehicles; (4) The vehicle has not obtained the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection validity period. Levels of flooded cars: Flooded cars can generally be classified into three levels—water-damaged cars, semi-submerged cars, and fully submerged cars. These three levels of flooded cars cannot be completely repaired. This is because a flooded car is highly likely to develop internal engine faults, making it impossible to start the vehicle.

Is It Safe to Store Gasoline in an Iron Drum in the Trunk?

Gasoline requires careful handling no matter where it is stored. While drivers often keep spare gasoline in the trunk, it is generally not recommended. Below are additional details: Composition: Storing gasoline in the trunk, especially in plastic containers, is unsafe. Gasoline stored in plastic containers inside the trunk poses significant hazards. Plastic containers are made from high-molecular insulating materials such as polyethylene and polyvinyl chloride. Reason: Gasoline is classified as a Class A flammable liquid with a flash point below 28°C and a lower explosive limit under 10%. When gasoline is stored in plastic containers, the friction between the gasoline and the container walls during filling, pouring, or vibration can generate electron movement due to contact potential difference, leading to the accumulation of positive and negative charges and the production of static electricity. If gasoline must be stored in the trunk, it should be placed in a sealed iron drum, and the temperature inside the trunk should be monitored.
