What is the reason for the abnormal noise in the left front wheel of the Lavida?

What are the consequences of continuously using the service brake on a long downhill slope?

Continuously using the service brake on a long downhill slope can cause the brake temperature to rise, leading to a sharp decline in braking effectiveness. Here are the consequences of continuously using the service brake on a long downhill slope: 1. If the brakes are continuously applied on a long downhill slope, the brake pads will overheat, resulting in reduced braking force. 2. There is a risk of losing braking ability, leading to brake failure. Therefore, it is recommended to use a lower gear and employ engine braking on long downhill slopes. Here is an introduction to engine braking: 1. Engine braking refers to lifting the accelerator pedal without depressing the clutch, utilizing the compression resistance generated by the engine's compression stroke. This creates internal friction and intake/exhaust resistance, which act as braking forces on the drive wheels. 2. Engine braking is essentially "coasting in gear"—keeping the gear engaged without supplying fuel. In this state, the engine no longer provides traction to the vehicle. Instead, the rotation of the wheels drives the transmission system, and the idling engine generates a counteracting resistance. The higher the gear, the less resistance the engine exerts on the vehicle, and vice versa.

Can the original owner cancel the insurance after the vehicle is transferred?

Vehicle transfer can cancel the insurance. Normally, after the vehicle is transferred, there are two ways to handle the vehicle insurance: one is to apply for changes to the policy information of the vehicle. This requires providing materials such as the policy invoice, the original insurance label, the vehicle transfer transaction invoice, the property registration certificate or driving license, and the ID cards of both parties involved in the transaction. These documents should be submitted to the original insurance company's business outlet for processing. It is important to note that both the original owner and the new owner (or their authorized agents) must be present in person. The other option is for the original owner to apply for cancellation of the vehicle insurance policy. The original owner can take the insurance policy to the original insurance company's business outlet to cancel the insurance. However, this situation is generally applicable to commercial auto insurance. After the contract is terminated, the insurance company will only charge premiums for the period from the start date of the insurance to the cancellation date on a pro-rata basis, and the remaining premium will be refunded accordingly. Article 38 of the "Insurance Law of the People's Republic of China": Before the commencement of insurance liability, if the policyholder requests to terminate the contract, they shall pay the insurer a handling fee, and the insurer shall refund the insurance premium. After the commencement of insurance liability, if the policyholder requests to terminate the contract, the insurer may collect the insurance premium for the period from the commencement of insurance liability to the termination of the contract, and the remaining portion shall be refunded to the policyholder. Article 39: The insured value of the subject matter of insurance may be agreed upon by the policyholder and the insurer and specified in the contract, or it may be determined based on the actual value of the subject matter of insurance at the time of the insured event. The sum insured shall not exceed the insured value; any portion exceeding the insured value shall be invalid. If the sum insured is lower than the insured value, unless otherwise stipulated in the contract, the insurer shall bear the liability for compensation in proportion to the ratio of the sum insured to the insured value. Process for canceling insurance after vehicle transfer: Visit the business office in person. Required materials include: an application for cancellation, the policyholder's ID card, a copy of the bank card, the insurance policy, and the premium invoice. Authorize an agent to handle the process at the business office. Required materials include: an application for cancellation, a power of attorney, the policyholder's ID card, a copy of the bank card, the insurance policy, and the premium invoice. However, it is important to note that if the auto insurance has already been purchased, canceling it now will result in certain financial losses, especially if the cancellation is not done properly, which may lead to greater risks of loss. Types of auto insurance: Compulsory Traffic Insurance (CTI): [Full name: Motor Vehicle Traffic Accident Liability Compulsory Insurance] is the first compulsory insurance system implemented by national law in China. The "Regulations on Motor Vehicle Traffic Accident Liability Compulsory Insurance" [hereinafter referred to as the "Regulations"] stipulate that CTI is a compulsory liability insurance where the insurance company compensates the victims [excluding the vehicle occupants and the insured] for personal injury, death, or property damage caused by road traffic accidents within the liability limits. Vehicle Damage Insurance: This covers losses to the insured vehicle caused by natural disasters (excluding earthquakes) or accidents within the scope of insurance liability. The insurer compensates according to the terms of the insurance contract. Unlike third-party liability insurance, this covers the insured's own vehicle. If you value your car, you should purchase this insurance. Comprehensive Theft Insurance: Full name: Motor Vehicle Comprehensive Theft Insurance. This insurance covers losses due to the entire vehicle being stolen, robbed, or seized, as well as reasonable repair costs for damages or missing parts and accessories during such events. Documents required from the original owner for a used vehicle transfer include: the registration certificate, driving license, and ID card.

Why is it said that air conditioning water corrodes car paint?

Air conditioning water is the moisture condensed from the air by the evaporator. It is pure water and non-corrosive, having no effect on car paint. Specific reasons for the increase in car air conditioning water: Because the car cooling system is located inside the dashboard, equipped with an evaporator: when the air conditioning is turned on, the surface temperature of the evaporator is very low, and the moisture in the hot air inside the car will condense on the heat-absorbing fins of the evaporator. The plastic housing of the evaporator collects the water droplets and drains them out of the car through pipes. If the vehicle stops and restarts after a period of driving, a pool of very clean and transparent water can be seen on the ground under the car, which is the water discharged by the car air conditioning. When using car air conditioning in summer: sometimes the compressor located in the engine compartment (low-pressure area) can also condense moisture from the air, dripping onto the ground (sometimes the amount of water is even greater than the drainage from the evaporator). If the low-pressure pipes of the car air conditioning are not wrapped with insulating foam: the surface of the pipes can easily condense moisture from the air, and water droplets will also condense and accumulate at the lowest point of the pipes, dripping down.

Park in Neutral or First Gear?

When parking, you can choose either neutral or first gear. For short-term parking, neutral gear is suitable; for long-term parking, you must engage the P (Park) gear. Regardless of the gear selected, always remember to engage the handbrake. Additionally, parking in first gear is also an option. Using first gear won't harm the car and is suitable for specific scenarios. The following situations are appropriate for parking in first gear: 1. For older vehicles, the internal springs and cables of mechanical handbrakes may experience wear and fatigue, affecting braking performance or even causing failure. In such cases, using first gear along with the handbrake reduces the load on the handbrake, extending its lifespan. 2. When parking on an uphill slope, using first gear + handbrake can prevent the car from rolling backward.

Is it necessary to change from water cooling to oil cooling for cars?

It is not necessary to change from water cooling to oil cooling for cars, and the reasons are as follows: Currently, there are three main types of coolant used in cars: ethylene glycol antifreeze, waterless antifreeze, and cooling oil. The vast majority of cars use ethylene glycol antifreeze because it is cost-effective and performs well, making it widely adopted. If you switch to oil cooling, the first issue is the higher cost, and for ordinary cars, it is unnecessary. Unless there are specific cooling requirements, there is no need to make the change.
