What are the disadvantages of having too much antifreeze?

1 Answers

There is no harm in having too much antifreeze. The excess antifreeze will expand due to heat during vehicle operation and overflow from the pressure relief valve, which is not harmful but may leave some stains. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion all year round. In addition to ensuring the engine operates within the normal temperature range, antifreeze also provides anti-corrosion protection for components of the cooling system. It is important to maintain the antifreeze level within the reasonable range in the car radiator, i.e., between the upper and lower limits marked on the radiator.

What is the middle button on a car key for?

The middle button on a car key is for opening the trunk. A typical car key usually has three buttons: unlock, lock, and open trunk. Here's an extended introduction to their functions: 1. Unlock button: This button should be very familiar - pressing it once will open the car doors. There's a hidden feature: pressing the unlock button once only opens the driver's door; pressing it twice unlocks all four doors; holding the unlock button for several seconds will simultaneously open all four windows. On some models, the sunroof will also open. 2. Lock button: Pressing this will lock all four doors. It also has a hidden function - remote window closing. 3. Trunk release button: Holding this button (or pressing twice for some models) will automatically open the trunk. Some vehicles even feature a hands-free trunk opening system where making a kicking motion under the rear bumper (while the key is within range) will automatically open the trunk.

What are the advantages of the Peugeot chassis?

Peugeot chassis adopts the new-generation chassis system developed by the PSA Group, with standardized workmanship, delivering a driving experience of 70% comfort and 30% handling, providing overall smooth and comfortable driving. Below is an introduction to the Peugeot chassis: 1. Smoothness: Peugeot performs well under low to medium speed conditions. At 60km/h, the front/rear seat smoothness is 7.46h/4.19h; at 80km/h, it is 7.46h/3.74h. As speed increases, the front seat smoothness does not weaken. However, at 100km/h, with further speed increase, the smoothness of the front/rear seats begins to decline but still maintains good performance. 2. Comfort: Peugeot's shock absorption effect is closely related to its dual-stage damping design. Under high-frequency small-amplitude vibrations, the damping is softer, absorbing a large amount of vibration. In the case of short-frequency large-amplitude vibrations on rough roads, Peugeot implements stiffer damping, enhancing stronger vehicle support.

How to Remove Adhesive from Car Window Tint Film?

Methods to remove adhesive from car window tint film include: 1. Use a cotton swab to apply vinegar to the residual adhesive. Once the vinegar and adhesive blend, wipe it clean with a cloth; 2. Apply essential balm to the adhesive and scrape it off with a knife; 3. Evenly apply alcohol to the residual adhesive. Once the adhesive is softened by the alcohol, wipe it off; 4. Spray a specialized thermal insulation cleaner on the residual adhesive. It will dissolve quickly, and you can then wipe it clean with a cloth. The functions of car window tint film are: 1. Thermal insulation: Blocks some heat, reducing air conditioning energy consumption for energy-saving effects; 2. UV protection: Effectively blocks ultraviolet rays, protecting the dashboard from radiation and extending its service life; 3. Anti-explosion function: If the car's front windshield is shattered by external force, the fragments will not scatter, ensuring driver safety; 4. Anti-glare: Significantly reduces the intensity of glaring light.

Does the Study and Deduction Policy Affect the Driver's License?

After participating in the Study and Deduction program, you can continue to accumulate demerit points, as it only reduces the existing points on your driver's license and does not affect its usage. The Study and Deduction policy allows motor vehicle drivers to reduce the demerit points for traffic violations by receiving education. Within one scoring cycle, a maximum of 6 points can be deducted. There are three ways to participate in the Study and Deduction program: 1) Online study (accumulating at least 30 minutes over 3 days) and passing the exam can reduce 1 point; 2) Attending on-site study sessions (each session lasting at least 1 hour) and passing the exam can reduce 2 points; 3) Participating in traffic safety public welfare activities (1 hour per session) can reduce 1 point. The Study and Deduction program has a dedicated question bank, covering topics such as safe driving knowledge, highway driving knowledge, civilized driving knowledge, driving psychology, common traffic signs, road markings, and traffic police hand signals. The Study and Deduction exam consists of 20 questions, with a perfect score of 100 points. A score of 90 or higher is required to pass. Accumulating 3 wrong answers will result in exam failure.

How Long Does It Take for a Submerged Car Chassis to Be Affected?

When a car chassis is submerged to the point of accumulating water, it can be affected immediately, as there is no fixed time frame due to varying drainage efficiency among vehicles. Generally, water entering the chassis does not cause significant issues, but if the water level rises above half of the tire, it is crucial to brake first upon exiting the water to expel the moisture and prevent affecting braking performance. Below are the methods to handle water entering the chassis: 1. Accumulated water in the chassis: While there is always a possibility of water entering the chassis, cars are designed to drain it naturally. However, if water accumulates, the chassis must be cleaned. During the cleaning process, it is essential to pay attention to rust prevention, as stagnant water is highly likely to cause rust. 2. Maintenance: The simplest protective measure is to apply a layer of waterproof coating directly onto the chassis, effectively blocking external water from entering the interior. During this maintenance, it is important to check whether the chassis's internal self-draining system is functioning properly. If not, maintenance should be performed accordingly.
