Why Can't the Spare Tire Come Off After Removing the Screws?

The reason the spare tire doesn't come off after removing the screws is that the jack hasn't been used. Although the tire screws are removed, the tire is still pressed down by the weight of the vehicle itself, preventing it from coming off. Solution: First, connect the jack's power source to the car's main driver's seat power supply. Then, place the jack at the front end of the tire to be removed and wait for the car to be lifted after powering on. Next, attach the electric wrench head to the main body and start pressing the electric wrench's switch to rotate and remove all the screws of the tire. This way, the tire will naturally fall off once all the screws are removed. Methods to Prevent Car Tire Screws from Being Unable to Remove: Tire screws need to be replaced after a certain period of use; otherwise, they may become impossible to remove due to rust. When using an impact wrench to install tires, be careful not to tighten them too much to avoid future difficulties in removal.

What is the difference between upgrading a license and taking a direct test?

The differences between upgrading a license and taking a direct test lie in the start date, probation restrictions, and cycle points. Start Date: For a directly obtained driver's license, the initial issuance date and the effective start date are the same day. In the case of an upgraded license, the initial issuance date and the effective start date will not be the same day. Probation Restrictions: After successfully upgrading a license, driving a small passenger car during the probation period is not subject to probation restrictions. With a directly obtained license, driving any vehicle is subject to probation restrictions. Cycle Points: Upgrading a license requires that there are no records of 12 points in the previous scoring cycle and the current scoring cycle, while there is no such restriction for a directly obtained license.

Can a Car with Exterior Modifications be Transferred?

Whether a car with exterior modifications can be transferred depends on the extent of the modifications. Can be transferred: For modified vehicles that have gone through formal procedures, such as changing the color at the local vehicle management office or re-engraving the engine number, as long as these changes are recorded in the motor vehicle registration certificate, the transfer can proceed normally. Cannot be transferred: For vehicles modified without authorization, whether it involves adding accessories, tire modifications, or other changes, if the modifications significantly deviate from the factory specifications, the vehicle must be restored to its original condition before the transfer. Otherwise, the vehicle will fail the pre-inspection during the transfer process and cannot be transferred.

Does Fast Consumption of Urea Damage the Vehicle?

Fast consumption of urea can harm the vehicle. Urea plays a crucial role in the vehicle's power and fuel consumption. If urea is consumed too quickly in a truck, it needs to be repaired at a 4S shop. The function of adding urea: Adding urea is for vehicles with diesel engines because diesel engines emit harmful nitrogen oxide gases, causing environmental pollution. Vehicles with diesel engines need to add urea to catalyze the conversion of nitrogen oxides into nitrogen and water, which are then emitted, reducing the harm of these gases to the human body. How urea works in vehicles: Urea is injected into the vehicle's exhaust pipe through the urea injection system, where it chemically reacts with the truck's exhaust gases. This process converts the vehicle's exhaust gases into water and nitrogen, achieving energy savings and emission reduction.

Does One Hard Braking Cause Damage to the Car?

Occasional hard braking does not harm the vehicle, but frequent hard braking can cause damage. Occasional hard braking: When you brake hard, the ABS braking assist system and EPS electronic stability system activate to maintain normal vehicle operation. Aside from significant wear on the brake friction pads and tires, as well as slightly increased fuel consumption when restarting, other damages from an occasional hard brake are negligible. Especially for automatic transmission vehicles, braking after releasing the accelerator does not involve harming the transmission or engine. Frequent hard braking: Frequent hard braking causes considerable damage to the vehicle, mainly manifested in tire wear, brake pad wear, impact deformation of the suspension system, and impact damage to the drivetrain. Therefore, hard braking should generally be avoided. However, cars are carefully designed and won't fail immediately due to hard braking, so in emergencies, you should not hesitate to brake hard.

Does a New Car Need Running-in After CNG Conversion?

New cars do require running-in after CNG conversion. Conversion timing: It's advisable to wait until the vehicle completes its running-in period before converting to CNG. The standard running-in period for new vehicles typically ranges between 2,500 to 3,000 kilometers. During this period, engine speed should be maintained around 2,500 RPM to ensure proper contact, friction, and adaptation of all mechanical components. Reasons for post-running-in conversion: Compared to gasoline, natural gas has cleaner composition but is relatively drier. Using CNG during the running-in period may adversely affect gear engagement. It's recommended to wait until after the first 2,000-km maintenance before switching to natural gas fuel, which can effectively extend vehicle lifespan and reduce future maintenance requirements.
