Difference Between 91V and 91W Tires

What are the effects of water entering the clutch and causing difficulty in shifting gears?

Water entering the clutch and causing difficulty in shifting gears may not have a significant impact on driving in the short term, but over time, it could damage the clutch's three-piece set. Therefore, if you notice any abnormalities after water ingress, it's best to take the vehicle to a repair shop for inspection. When a vehicle drives through deep water, it can potentially lead to various malfunctions. Below is an introduction to the function of the clutch: 1. Clutch location: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power from the engine to the transmission. 2. Basic requirements for the clutch: Smooth engagement, rapid and thorough disengagement; easy adjustment and repair; compact size; lightweight; good wear resistance and sufficient heat dissipation capacity; easy and effortless operation. Commonly, clutches are divided into two types: jaw-type and friction-type. The clutch is installed between the engine and the transmission and is the assembly directly connected to the engine in the vehicle's drivetrain.

Must You Keep Windows Closed for Three Days After Tinting?

After tinting, you must wait for three days or even longer before opening the windows. The applied window film needs to dry completely to ensure normal use. Opening the windows prematurely may cause the film to peel or bubble, affecting its long-term performance. Here are additional precautions to take after tinting: 1. Avoid Washing the Car: Refrain from washing the car within three days after tinting to prevent moisture from causing the film to detach. 2. Defroster Lines: Avoid using the rear window defroster for a week. After tinting, you may notice a foggy appearance due to water vapor, which is normal as the film dries. Excess moisture can also negatively impact the defroster lines. Use a damp towel, sponge, or soft cloth to gently clean the film surface after installation.

Can the headlights of Volkswagen Santana Zhijun be replaced with LED lights?

The headlights of Volkswagen Santana Zhijun can be replaced with LED lights. The original headlights of Santana Zhijun are standard halogen headlights. The front headlights include low beam and high beam, which can be upgraded to LED lights; they also include turn signals and position lights. Below are the related details: Benefits of replacing headlights with LED lights: Long lifespan: Lasting 50,000 to 100,000 hours, generally requiring no replacement during the vehicle's lifetime; Cost-saving: Original bulbs are incandescent, consuming 21 watts each, while LED lights consume only 1 watt; Avoid fines: Due to the ultra-long lifespan of LEDs, the risk of receiving fines due to sudden bulb failure is eliminated; Circuit safety: The current in the vehicle's lighting circuit reduces from over ten amperes to less than one ampere, significantly lowering the risk of circuit fires. Introduction to car headlights: Car headlights include high beam and low beam, both designed to illuminate the road ahead. The difference lies in their range—one illuminates a shorter distance, while the other reaches farther. Typically, low beams illuminate a distance of about 30-40 meters with a coverage of approximately 160 degrees, whereas high beams focus the light more intensely, providing brighter and longer-range illumination.

What does FM on the car mean?

FM/AM refers to the radio function in the car. Here is some relevant information: 1. FM stands for Frequency Modulation band: The broadcast frequency range is 87.5~108MHz. Due to the different audio signal modulation methods used, the restored sound quality is clear, far better than the effect of amplitude modulation. For example, in wireless TV signals, the image uses amplitude modulation, while the sound uses frequency modulation. 2. Amplitude Modulation (AM) broadcasting: AM broadcasting modulates the audio signal onto the "amplitude" of a high-frequency carrier wave and transmits it into the air. The radio receives the AM radio signals in the air through a magnetic antenna or an external antenna, and then demodulates the audio signal through high-frequency tuning → intermediate frequency amplification → detection circuit. The audio signal is then amplified by the audio amplification circuit to restore the radio program content.

Can a Locked Vehicle Undergo Annual Inspection?

Locked vehicles can undergo annual inspection. Relevant details are as follows: 1. Vehicles displaying a locked status can be inspected annually: When a court imposes seizure, impoundment, or other protective measures on a vehicle, the purpose is to prevent the debtor from mortgaging or transferring the vehicle, which could affect ownership. These court-ordered protective measures do not interfere with the vehicle's annual inspection. 2. Annual inspection includes: (1) Checking whether the engine, chassis, body, and related equipment are clean, complete, and functional; whether the paint is uniform and aesthetically pleasing; whether major assemblies have been replaced; and whether they match the initial inspection records. (2) Verifying whether the vehicle's braking performance, steering control, lighting, exhaust emissions, and other safety features comply with the "Technical Requirements for Safe Operation of Motor Vehicles." (3) Confirming whether the vehicle has undergone modifications, redesigns, or alterations; whether the license plate, registration certificate, and vehicle records match the actual condition of the vehicle; and whether any changes have been properly approved and documented. (4) Inspecting the license plate, registration certificate, and enlarged license plate markings on the vehicle for damage, tampering, illegible text, or the need for replacement.

Are Car Batteries Lithium Batteries?

Car batteries are lead-acid batteries. Here is some related information about batteries: 1. Working principle: A battery, also known as a storage battery, is a type of cell that converts chemical energy into electrical energy. Typically, when people refer to a battery, they mean a lead-acid battery. This is a type of battery primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Maintenance methods: Avoid storing the battery in a discharged state. A discharged state refers to when the battery is not recharged promptly after use, which can easily lead to sulfation. Lead sulfate crystals can form on the electrode plates, blocking the ion channels and causing insufficient charging, which reduces the battery's capacity. The longer the battery remains in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan.
