Does Every Car Have Scratches?

Vehicle scratches are unavoidable. Here are the relevant methods for dealing with scratches: Light Scratches: Spray water and wipe with a towel. After cleaning, apply a polishing compound to the affected area and use a polisher at low speed, moving back and forth along the direction of the scratch. Move slowly and apply even pressure, ensuring no spots are missed. During polishing, keep the polishing pad and paint surface at room temperature. If the paint surface exceeds 40°C, spray water to cool it down. Stop polishing once the light scratches become invisible, then rinse off any remaining compound with water and dry with a towel. Avoid waxing immediately after polishing. If wax is applied right away, the paint may look glossy for the first few days, but after washing, the gloss will fade. Therefore, use a paint restorer to restore the paint first. Moderate to Severe Scratches: It is recommended to visit a professional auto maintenance facility for repair.

What are the signs of a broken car shock absorber?

When a car's shock absorber is damaged, there are usually signs such as body shaking and abnormal heat. Below is a detailed explanation of these symptoms: Body Shaking: For sedans, shaking the car body can help determine the performance of the shock absorber. Alternatively, you can observe the vehicle's rocking state after emergency braking. If the shock absorber fails, the car will rock significantly more times than under normal conditions. When the vehicle is stationary, forcefully hold the bumper or hood and shake it. When the shaking reaches its maximum amplitude, suddenly release your grip. Abnormal Temperature: The shock absorber converts the mechanical energy of wheel and body vibration into heat, which is then dissipated, thereby reducing vibration. The more vibration energy it absorbs, the higher the temperature of the shock absorber. When the shock absorber's energy absorption reaches saturation, the temperature basically stops rising. Typically, it takes about half an hour to reach a thermal equilibrium state.

Why CVT Transmission Fluid Generally Doesn't Need Replacement

Nissan's advanced CVT transmission can have its specialized fluid replaced every 200,000 kilometers. Many private vehicles may not even reach 200,000 kilometers before being replaced, leading to the viewpoint that CVT transmission fluid may never need replacement throughout the vehicle's lifespan. Transmission Fluid Replacement Intervals: Different vehicle models have varying replacement intervals. Below are the general guidelines for transmission fluid replacement; Manual Transmission: Manual transmission fluid is typically recommended for replacement every three years or approximately 100,000 kilometers; Automatic Transmission: Automatic transmission fluid is generally advised to be replaced every two years or around 40,000 kilometers; Continuously Variable Transmission (CVT): CVT fluid is usually suggested for replacement every two years or about 60,000 kilometers. Hazards of Not Replacing Transmission Fluid: Damage to the transmission's gear shift control mechanism; Abnormal wear of gears and clutch plates within the transmission; Impaired normal operation of the transmission, potentially leading to damage of the transmission valve body.

What does replacement vehicle insurance mean?

Replacement vehicle insurance refers to the coverage for expenses related to a temporary replacement vehicle. Below is an introduction to replacement vehicle expense insurance: Type of Coverage: Replacement vehicle expense insurance is an additional coverage under auto damage insurance. It can only be purchased if the vehicle is already insured under auto damage insurance. During the insurance period, if the insured vehicle is damaged due to an accident covered under the first clause of the auto damage insurance policy, requiring it to be repaired in a workshop, the insurer will cover the rental expenses for a replacement vehicle incurred by the policyholder, up to the limit specified in the insurance contract. Expense Documentation: During the insurance period, the compensation days are calculated cumulatively, with the total compensation days not exceeding the maximum number of days specified in the policy. For partial losses, the compensation is calculated by multiplying the daily compensation amount specified in the policy by the actual number of days from the date the vehicle is sent for repair and handed over until the date it is fully repaired and retrieved. For total losses, compensation is calculated based on the maximum number of compensation days specified in the policy.
