Does a car need waxing?

It is necessary to wax a car. Waxing can provide waterproofing and protection against acid rain, as the wax reduces the amount of water droplets adhering to the car body. For a brand-new car, it is recommended not to wax it within the first 5 months, as the new car already comes with a layer of wax, and additional waxing may damage the paint. Functions of car waxing: Waterproofing: Car wax can reduce the attachment of water droplets on the car's paint surface by 60%-90%. High-end car waxes can further flatten the remaining water droplets on the paint surface, minimizing the formation of dark spots, erosion, and damage caused by the focusing effect of intense sunlight. High-temperature resistance: The high-temperature resistance of car wax effectively reflects incoming light from different directions, preventing the light from penetrating the transparent paint surface, which can cause the base paint to age and discolor, thereby extending the lifespan of the paint. Anti-static effect: The anti-static effect of car wax mainly prevents static electricity on the car's surface. The principle is to block the friction between dust and the metal surface of the car. Depending on the thickness of the wax layer and the adhesion ability of the wax itself, the anti-static effect varies. Generally, anti-static car waxes are better at preventing friction between dust and the paint surface compared to regular car waxes. UV protection: The UV protection function of car wax works alongside its high-temperature resistance. UV-protective car waxes are designed to minimize the damage caused by UV rays to the car's surface. Polishing effect: Polishing is the most basic function of car wax. A waxed car will have an improved shine, restoring the vehicle's original bright and beautiful appearance.

What are the length, width, and height of the Highlander?

The 2021 Highlander's length, width, and height dimensions are 4965mm/1930mm/1750mm, which are official data. The length of the 2021 Highlander refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The Highlander is equipped with a 2.0-liter turbocharged engine with the model code 8AR-FTS. This engine has a maximum power of 162 kW and a maximum torque of 350 Nm. The engine's maximum power output is achieved at 5200 to 5600 rpm, and its maximum torque is available from 1800 to 4000 rpm. This engine features VVT-iW technology and hybrid injection technology, and it uses an aluminum alloy cylinder head and block. The engine is paired with a 6-speed automatic transmission (6AT). The 6AT transmission offers relatively better reliability and stability, and its gear-shifting smoothness is also commendable. The state has relevant regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include the side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, the significance of vehicle width data in the national standard is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the national standard stipulates that the total width of a vehicle must not exceed 2.5 meters to meet the requirements of public road usage.

What transmission is used in the Geely Emgrand?

Geely Emgrand's transmission is supplied by Punch Powertrain, a Belgium-based company headquartered in Sint-Truiden. Punch Powertrain is a provider of energy-efficient powertrain systems, with over 50 years of experience in the design and production of continuously variable transmissions (CVT). The company also specializes in the development, production, and supply of hybrid powertrains (48V and plug-in hybrid PHEV) and dual-clutch transmissions (DCT), along with their components. The CVT transmission in the Emgrand is the Punch VT2 automatic transmission, which can handle a maximum power of 98 kW and a maximum torque of 170 Nm. This transmission is widely used, with five product variants (VT1-VT5) designed for different torque capacities. It is employed by several domestic brands, including Geely Emgrand, Soueast Motor, Haima Automobile, and Hawtai Motor. When using the Geely Emgrand's transmission, the following points should be noted: 1. Do not delay transmission fluid changes for extended periods. While many modern transmissions claim to be maintenance-free, this does not mean the fluid never needs replacement. Prolonged use without changing the fluid can damage internal components such as bearings and housings. 2. Avoid coasting in neutral for long durations. While "experienced" drivers of manual transmissions may coast in neutral, doing so in an automatic transmission can cause overheating. Additionally, shifting back into Drive (D) from neutral may result in harsh engagement. 3. Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers attempt to showcase "smooth" operation by shifting gears prematurely, but this practice can severely damage transmission gears and lead to grinding or other failures over time. 4. Avoid frequently climbing steep slopes in Drive (D). Automatic transmissions may overheat under high loads or upshift prematurely, reducing climbing power. In such situations, use manual mode to lock in lower gears or switch to sport mode to protect the transmission. 5. Do not tow the vehicle over long distances. If the automatic transmission vehicle breaks down, use a flatbed tow truck to transport it while in Neutral (N). Towing with a rope or dragging the vehicle directly is not recommended.

Should You Use Cold or Warm Air to Defog Car Windows?

Both cold and warm air can be used to defog car windows, but warm air is slower than cold air. The most effective method is using cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing and achieving defogging. The method of using warm air is similar to cold air defogging, but it's important to note that warm air should not be used on rainy days as it may initially worsen the fog. When defogging car windows, the external air circulation should be turned on. The reason for car window fogging: There is a temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the side with the lower temperature will have a lower saturation vapor pressure on its surface compared to the surrounding environment, causing water vapor to accumulate on the glass surface in the form of tiny droplets, forming fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car without turning on the air conditioning promptly, the high humidity from exhaled breath can quickly cause the windshield to fog up. Turning on the air conditioning to blow cold air onto the windshield and using the dehumidification function can quickly remove the fog. If the humidity is too high and the air conditioning is not effective, slightly opening a window can quickly reduce the humidity inside the car. Combining both methods can yield faster results. Air Conditioning Heating: Use warm air to reduce the temperature difference and remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the front windshield, reducing the temperature difference between the inside and outside surfaces and preventing heavy fogging. However, the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. The temperature control should not be set to the coldest position, as this can cause the outer surface of the windshield to fog up over time. Applying Anti-Fog Spray: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains. This leaves a thin transparent protective film on the glass, effectively preventing water vapor from condensing and forming fog, especially useful in cold winters. Alternatives to anti-fog spray include dish soap, soapy water, glycerin, alcohol, or saline solution. After applying and letting it dry, wipe off any excess with a chamois or soft dry cloth to ensure the windows remain fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, opening the side windows can create airflow between the inside and outside of the car, reducing the temperature difference and gradually eliminating the fog. The principle is the same as using cold air from the air conditioning. However, this method has obvious drawbacks and cannot be used during rain, snow, on highways, or when the fog is heavy. Rear Window Heating: Most cars are equipped with a rear window heating function, though the button location may vary. Turning on the rear window heating switch will usually clear the fog within about a minute.

Where is the 9-digit engine number located?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number, like a person's ID number, represents each vehicle and contains crucial information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static brake power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer, model, and production number of the engine. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the vehicle engine number: Prefix: Includes product series code, generation symbol, and regional or corporate code, which are selected by the manufacturer as needed and must be approved and filed by the industry standardization unit. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Comprises symbols for structural features and usage characteristics. Suffix: Distinguishing symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol, and the rear section and suffix can be separated by a hyphen. Methods to check the vehicle engine number: Check the vehicle registration certificate; inspect the engine number on the motor vehicle registration certificate; look for the engine number on the purchase invoice; the factory certificate includes the engine number; the operation certificate of commercial vehicles can be used to query the engine number; check the vehicle insurance card. The engine number, composed of the prefix, middle section, rear section, and suffix, is an identification code assigned by the engine manufacturer according to relevant regulations, corporate or industry practices, and the attributes of the engine. It indicates the specific model of the vehicle, the exact production time, and the origin code information of the vehicle.
