Is the Vehicle Title Obtained at the DMV for a New Car?

Yes, the vehicle title for a new car is obtained at the DMV. Introduction to the New Car Green Book: The Green Book is the registration certificate, which is issued to the owner on the spot by DMV staff at the inspection site when the new car is registered. The so-called Green Book refers to the "Motor Vehicle Registration Certificate," which records the vehicle's registration date and manufacturing date and is kept by the vehicle owner. Conditions for Obtaining the Green Book: You can only get the Green Book if you purchase the car in full. If you finance the car, the Green Book must be mortgaged to the lending bank or company. Once the loan is fully repaid, you need to take the Green Book to the DMV to release the mortgage.

Is it necessary to replace a damaged rear wheel liner?

It is necessary to replace a damaged rear wheel liner. Effects of a damaged wheel liner: If the wheel liner is damaged, it can cause noticeable noise while driving and may reduce the vehicle's sound insulation performance. Additionally, after the wheel liner is damaged, dirt such as mud, sand, branches, and leaves can easily accumulate on the chassis during driving. Over time, this can have a significant impact on the chassis. If the wheel liner is severely damaged, it may also increase the vehicle's air resistance, leading to higher fuel consumption. Function of the car wheel liner: The wheel liner (fender liner) helps prevent water and mud from entering, and it also prevents gravel and mud kicked up by the wheels from splashing onto the bottom of the vehicle, reducing damage and corrosion to the chassis.

Is Coating or Crystal Coating Better for New Cars?

Crystal coating is better for new cars. The main differences between the two are: 1. Difference one: Crystal coating forms a solid crystalline layer on the paint surface to protect it, whereas coating and glaze sealing do not form crystals on the paint surface, and their hardness is also lower than that of crystal coating. 2. Difference two: In terms of durability, coating protection lasts about 1 year, while crystal coating can last up to 2 years, offering longer lifespan and more stable performance. 3. Difference three: Crystal coating is more stringent and involves a complex application process in a dust-free environment. The products used in coating, although they can form a layer on the paint surface, do not crystallize or harden. Over time, they react with oxygen in the air, eventually decomposing and being washed away by water.

Why Do Cars Drip Water in Summer?

It is quite normal for a car's exhaust pipe to drip water, which indicates that the engine is working properly, with complete combustion and good atomization effect. Reasons: The dripping water from the car's exhaust pipe is due to the fact that after the gasoline is completely burned, it produces water and carbon dioxide. Water at high temperatures is in the form of water vapor, which is colorless and transparent. However, when the temperature drops below 100 degrees, the water vapor condenses into water. If the condensed water droplets are very small and suspended in the air, the water vapor appears as white gas. When the ambient temperature is low, the white smoke from the exhaust pipe is water vapor. If the condensed water droplets accumulate, they turn into water. Minimum conditions for exhaust pipe dripping: The mixture ratio of gasoline and air is correct. The engine's cylinder pressure is normal. The exhaust pipe temperature is low.

What to Do When the Front Windshield Is Frozen?

Solutions for a frozen front windshield are as follows: 1. Warm up the car sufficiently to allow the engine coolant temperature to rise. When there is frost on the front windshield, do not use the wipers to scrape the ice. Instead, let the car idle to warm up, and avoid driving slowly to warm it up. 2. Use the heater to blow warm air on the front windshield. Once the engine coolant temperature has risen, turn on the heater and set it to blow upward onto the windshield at the highest setting. 3. Use a car defroster spray. If you want to melt the frost on the windshield faster, you can use a specialized car defroster spray. 4. Methods to prevent frost on the windshield. If you open the windows when parking at night to equalize the temperature inside and outside the car before closing them, the car glass will not frost over the next day.

Why are car refrigerant pipes not wrapped?

Car refrigerant pipes are not wrapped because they need heat dissipation. The functions of an air filter include the following 3 points: 1. Provide fresh air: It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the cabin, preventing passengers from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: It keeps the cabin air clean and free from bacterial growth, effectively separating solid impurities such as dust, core powder, and grinding particles from the air; it effectively blocks pollen, ensuring that passengers do not experience allergic reactions that could affect driving safety. 3. Adsorb harmful substances: It adsorbs moisture, soot, ozone, and odors from the air, with strong and durable moisture adsorption capabilities.
