How to Remove Overspray from Car Body?

For overspray that has not completely dried, you can spray cleaner on the overspray and wipe it off with a towel; for dried overspray, you can use 2000-grit polishing sandpaper to grind off the overspray on the paint surface. Below are specific methods for dealing with overspray on cars: 1. For overspray that has not completely dried, spray cleaner on the overspray and wipe it with a soft towel. After wiping the entire car, use detailing clay to scrub the paint surface. 2. For dried overspray, first wash the car thoroughly, then use 2000-grit polishing sandpaper to grind off the overspray on the paint surface. After that, perform a polishing treatment to restore the gloss of the paint surface, and finally, carry out a full paint surface maintenance. The vehicle's paint consists of four layers: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. The electrocoat layer serves to prevent rust and enhance the adhesion of the paint layers. The primer layer connects the basecoat layer and the electrocoat layer. The clearcoat layer is the outermost layer of the paint, primarily functioning to enhance the paint's gloss, improve texture, protect against UV rays, and prevent minor scratches.

How often should the transmission fluid in the Jade be changed?

The transmission fluid in the Jade should be changed every two years or after driving 40,000 kilometers. The method for changing the transmission fluid in a car is as follows: 1. First, lift the car and place a large container underneath to catch the used fluid. Use an appropriate screwdriver to remove the inner and outer covers of the transmission, being cautious as some transmission fluid may spill out. 2. After a few minutes, when most of the fluid has drained, carefully remove the last oil pan, ensuring to support it by hand as it still contains a significant amount of used fluid. Upon removal, you will notice residue at the bottom of the oil pan. 3. Carefully remove the transmission fluid filter, which will clearly reveal the solenoid valve controlling gear shifts. 4. Remove the oil pan gasket and clean the surrounding area. If there are hard-to-reach spots, use tools for thorough cleaning. Over time, the rubber on the gasket may stick to the machine edges, requiring a small scraper and carburetor cleaner for easier and more thorough removal. 5. Wipe all cleaned transmission fluid filtration components with cotton cloth and reinstall them. Filters are generally for one-time use, so replace them along with the new fluid and gasket during the oil change.

Is it necessary to clean the three-way catalytic converter of the New Transit?

The three-way catalytic converter generally does not need cleaning. The failure rate of the three-way catalytic converter is very low, and cleaning is typically done using a no-disassembly method similar to an IV drip. Usually, the three-way catalytic converter should be inspected and cleaned as needed every 30,000 kilometers. It is advisable to clean the three-way catalytic converter whenever the fuel injectors, throttle, and intake tract are serviced. Additionally, it is best to clean the three-way catalytic converter before the annual vehicle inspection to ensure smooth passage of the emissions test. When fuel quality is poor, sulfur, phosphorus, lead, and manganese-containing anti-knock agents in the fuel can form chemical complexes inside the three-way catalytic converter after combustion. Due to its honeycomb structure, the three-way catalytic converter is prone to clogging. The use of manganese-containing anti-knock agents in fuel, sulfur- and phosphorus-containing antioxidants in lubricants, and traffic congestion can easily lead to poisoning, failure, or clogging of the three-way catalytic converter. As a critical component of automotive exhaust treatment, the three-way catalytic converter significantly reduces pollutants in vehicle emissions, and all exhaust gases must pass through it. If the three-way catalytic converter is damaged or clogged, it is similar to a blocked exhaust pipe, resulting in a noticeable decrease in vehicle power, increased fuel consumption, and severe exhaust pollution.

What Does the Number of Axles on a Vehicle Mean?

The function of the number of axles on a vehicle is to bear the load of the vehicle and maintain its normal operation on the road. Vehicles are categorized by the number of axles: single axle, double axle, front four rear four, front four rear eight, semi-trailer for more axles, two-axle tractor with three-axle trailer, three-axle tractor with three-axle trailer. Below are the applications of vehicle axle counts: 1. Ordinary family cars generally use a single axle. 2. For highway transport vehicles with a total mass less than 19 tons and vehicles not subject to road or bridge axle load limits, such as mining dump trucks, a simple and cost-effective two-axle configuration is typically used. 3. Highway transport vehicles with a total mass between 19-26 tons adopt a three-axle configuration, while vehicles with even greater total mass should use four or more axles. 4. Generally, three-wheeled trucks have a capacity of 2 tons; low-speed trucks (four wheels with a maximum design speed less than 70 km/h) 4.5 tons; two-axle trucks 17 tons; three-axle trucks 25 tons (27 tons for vehicle combinations consisting of a two-axle vehicle and a one-axle trailer); four-axle trucks 35 tons; five-axle trucks 43 tons; six-axle and above trucks 49 tons.

Why is the car navigation screen very dark and almost invisible?

If the car's central control screen becomes dark, it may be due to damage to the display and require replacement. Here is the relevant introduction: 1. Purpose: The uses of the car's central control display screen include providing a visual reversing image, playing DVDs, and navigation; all navigation technologies involve positioning the navigator's location by comparing it with known positions or patterns. 2. Navigation: This is a field of study that focuses on monitoring and controlling the process of moving a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aerial navigation, and space navigation. It is also an art term used for the professional knowledge that navigators employ to perform navigation tasks.

Can a temporary license plate be used in another city?

During the use of a local temporary license plate, the vehicle is not allowed to leave the city, while an out-of-town temporary license plate permits travel outside the city. Relevant information is as follows: 1. Introduction to temporary license plates: A temporary license plate serves as an interim plate before a new vehicle obtains its official license plate. During this period, the temporary license plate must be used for driving on the road, and it holds the same legal effect as an official license plate. Once the official license plate is obtained, the temporary license plate becomes invalid. 2. There are four types of temporary license plates: Temporary license plates within the administrative jurisdiction (for new cars sold within the city), temporary license plates across administrative jurisdictions (for new cars sold to other cities), temporary license plates for test vehicles (test cars, engineering prototypes, etc.), and temporary license plates for special vehicles.
