Brake fluid definitely needs to be replaced. Here is the relevant information: 1. When braking, water molecules are generated under high temperatures. Additionally, brake fluid is a high-concentration liquid with strong moisture absorption capability, so its water content will inevitably increase over time, affecting the vehicle's braking performance. 2. Regular replacement of brake fluid is crucial. As for the replacement interval, it's generally recommended every 2 years or 40,000 kilometers. Of course, the most direct method is to check the brake fluid's water content - replacement is needed when it exceeds 3%.

Is the Tiguan L four-wheel drive?

The Tiguan L is available in front-wheel drive and front-engine four-wheel drive configurations. Here is more information about front-wheel drive and front-engine four-wheel drive: 1. Front-wheel drive (FF) means the engine is positioned at the front and drives the front wheels. The advantages include a simple mechanical structure, good engine cooling conditions, spacious interior, easy layout, reduced vehicle weight, better fuel efficiency, and convenient maintenance. The disadvantages are that since the front wheels handle both steering and driving, high-speed stability is relatively poor, the drive wheels are prone to slipping when climbing hills, and the vehicle is more likely to roll over during high-speed descents. 2. Front-engine four-wheel drive means the engine is positioned at the front and all four wheels drive the vehicle. Since all four wheels have power, compared to designs that rely solely on front-wheel or rear-wheel drive, front-engine four-wheel drive offers superior handling performance. The advantages of front-wheel drive are all related to the drivetrain—since front-wheel drive vehicles lack a driveshaft connecting to the rear wheels, the components are fewer and more concentrated, resulting in direct power transmission. Therefore, front-wheel drive vehicles are cost-effective, efficient, spacious, lightweight, and fuel-efficient.

How to Deal with Oxidized and Whitened Red Car Paint?

Through grinding and polishing to remove the oxidized layer of the paint, the vehicle can regain its luster, temporarily restoring the color to its original state when it was new. Followed by coating. Coating involves applying a protective film over the car's surface to isolate and protect the paint. This film itself is not affected by external oxidation. Repainting is a common method to restore the gloss of car paint. However, repainting is often constrained by factors such as raw materials, spraying equipment, and construction techniques. The coating material contains silicone, rich in blemish cream and titanium dioxide, both of which are extremely stable in nature, forming a protective layer on the car paint surface that lasts up to three years.

What to do if the driver's license expires within one year?

If the driver's license has been expired for less than 12 months, you can proceed with the renewal as usual. When the driver's license expires, you should go to the vehicle management office to apply for a replacement. You need to bring the identity proof of the vehicle owner and standard photos of the vehicle, etc. If the driver's license has expired, it is as if you do not have a driver's license, and the vehicle cannot be driven on the road. If caught by traffic police, the owner will be detained. In insurance contracts, a vehicle with an expired driver's license is considered unqualified. If a vehicle insurance accident occurs, no claims will be paid.

How to Test the Engine Oil Level Sensor?

Disconnect the wiring harness plug of the engine oil pressure sensor and remove the sensor. Screw the hose connector of the oil pressure gauge into the threaded hole of the oil pressure sensor. Place the oil pressure gauge in a location where it will not come into contact with rotating or high-temperature engine components. Start the engine and check for any oil leaks at the oil pressure gauge connection. If leaks are found, turn off the engine and retighten the connection. Run the engine until it reaches normal operating temperature, then check the oil pressure gauge readings at both idle and 2000 r/min.

How to Remove and Replace the Low Beam Headlight of the New Sylphy?

Open the engine compartment cover, locate the rear cover of the headlight at the headlight position, unplug the connector, and unscrew the bulb. More related information is as follows: 1. The low beam headlight is designed for close-range illumination, with a large coverage area (160°) and a short illumination distance, and the focus cannot be adjusted. The low beam must be turned on in the following situations: driving in areas without streetlights at night, driving at dusk when it is relatively dark or at dawn when the light is just appearing; if encountering heavy fog, snow, or heavy rain that obstructs visibility, the low beam must be turned on even during the day; on some roads where there are lighting facilities but the brightness is insufficient, the low beam should also be turned on. 2. Although the low beam has an illumination distance of about 30 meters, it has a very noticeable beam cutoff line. Most car low beams have an illumination distance of 30-40 meters, with the beam cutoff line at about 12-18 meters. The area in front of the beam cutoff line is brightly lit, allowing clear identification of objects, and a clearly visible illuminated area of 2-3 meters in diameter can be seen on the ground. The area from behind the beam cutoff line to 30-40 meters mainly relies on ground-reflected light sources. In this area, brightly colored objects can be distinguished, but dark-colored stationary objects on the road are not easily noticeable.

How to Remove the Gear Knob of Geely Borui?

Most manual transmission gear knobs are screwed on, and there may be one or two fixing screws. Remove the fixing screws and rotate the gear knob counterclockwise to take it off. Some models have gear knobs connected with dust boots. In this case, you need to loosen the dust boot first and pry it out with a trim panel tool. Since the replacement here is not an original gear knob, you need to install the included fixing bolt. Put the fixing bolt on the gear lever and tighten it clockwise. Finally, screw the new gear knob on.
