Should the Rubber on the Crankshaft Pulley Be Replaced if It's Aged?

If there are abnormalities, it should be replaced. Even if the belt wear is not severe, the engine belt idler pulley should also be replaced. Correct mistakes promptly: Some engines use flat-shaped fan belts. When installing them on the pulley, check the fit between the belt and the pulley. The flat-shaped belt should fit well with the pulley; otherwise, the belt's service life will not be long. Some models use V-belts, and if any errors occur, they should be corrected promptly. Risks of not replacing: If not replaced in time, driving may sometimes cause excessive idler pulley wobbling, accelerating belt wear. In some cases, the idler pulley may seize and grind the belt down completely, or the pulley itself may detach, causing the belt to disengage. This results in the loss of power to the engine's generator, water pump, power steering pump, air conditioning pump, and other components that rely on engine power, leading to vehicle breakdown and inability to operate normally.

How many points can a new driver deduct in the first year?

During the first-year probation period of a C1 driver's license, a maximum of 11 points can be deducted. For C-class licenses and motorcycle driver's licenses, as long as the points do not reach 12 during the probation period, there will be no issues, and the probation period will not be extended. However, if 12 points are accumulated during the probation period, the license will be directly revoked, and the driver will need to retake the driving test from scratch to legally drive again. Therefore, it is crucial for C-class license holders not to accumulate 12 points during the probation period—the maximum allowable is 11 points. No other adverse consequences: If a new driver accumulates 6 points, as long as the traffic violation fines are paid, the 6 points will be cleared and will not carry over to the next scoring cycle, nor will they result in any other negative consequences. Probation period extended by one year: However, for large passenger vehicles, tow trucks, city buses, medium-sized passenger vehicles, and large truck driver's licenses, if 6 or more points (but less than 12) are accumulated during the one-year probation period, the probation period will be extended by one year.

What are the troubleshooting steps for a complete power loss in diesel vehicles?

The car's generator may have malfunctioned or there could be an issue with the electrical circuit. Below is relevant information about diesel vehicles: Precautions: Pay attention to excessively high engine coolant temperature. First, move the vehicle to a ventilated and shaded area. Open the engine hood and wait for the coolant temperature to decrease. If it's necessary to open immediately, use a large towel soaked in water to cover the coolant reservoir cap, then attempt to slowly open it. When steam emerges, quickly move your hand away and wait until the steam completely dissipates before finally opening the reservoir cap to add coolant. Scrapping timeline: When the mileage reaches 600,000 kilometers, mandatory scrapping is enforced, but the specific condition of the vehicle should also be considered. For commercial vehicles, the scrapping period is 8 years. Each vehicle has its own scrapping timeline from the date of purchase, as stipulated by national transportation authorities through a regulatory system that specifies safety inspection requirements based on seating capacity and usage duration during the vehicle's operational life.

Why Are Gas Lamps So Bright?

Because gas lamps use vaporized kerosene to burn efficiently at extremely high temperatures, heating a mesh made of various rare earth elements to emit light, thereby achieving a brightness that flames alone cannot match. Below is an introduction to related car lighting content: Halogen Headlights: Halogen headlights are currently the most commonly used type of car headlight source by major automakers across various vehicle models. Due to their relatively low cost, they are very suitable for more economical, lower-priced vehicles. Xenon Headlights: Xenon lamps are stimulated by high-voltage current to emit light, resulting in a longer lifespan and better energy efficiency compared to halogen lamps. Moreover, their brightness is significantly improved by 300% over halogen lamps. LED Headlights: LED headlights are increasingly entering people's field of vision. While LEDs may often bring to mind stylish daytime running lights, this type of light source, with its numerous advantages, has become the choice for more and more car headlight illumination.
