What Are the Reasons for Antifreeze Loss?

It is normal for antifreeze to have a slight loss, as although the entire cooling system is sealed, the coolant reservoir cap has a pressure relief hole. Methods to determine if antifreeze is insufficient: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to a lack of antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Inspect the water level markings on the antifreeze reservoir. The normal antifreeze level should be between the maximum and minimum marks. To determine if antifreeze is lacking, check the markings. If the antifreeze level is below the minimum mark, it indicates a shortage. Precautions for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connections to different parts. Antifreeze flows through the five-way hose and is then distributed to various parts of the car to function. If there are signs of antifreeze leakage in this section, replace the hose or resecure the connections as needed.

What is the purpose of using a tension pulley in belt drives?

The purpose of using a tension pulley in belt drives is to adjust the initial tension of the belt. More details are as follows: 1. A tension pulley is a follower wheel pressed against the belt to control its tension. It is a tensioning device for belt drives. When the center distance of the belt cannot be adjusted, a tension pulley can be used to tighten the belt. The belt pulley transmits power through friction, so the belt must be tensioned during installation. However, after working for a period of time, the belt may stretch and become loose, leading to slippage, and thus requires re-tensioning. 2. If the center distance between the two drive pulleys cannot be adjusted, a tension pulley must be used to ensure normal transmission and prevent slippage. 3. The tension pulley uses a spring or hydraulic pressure to generate a force that tightens the belt, ensuring the belt applies appropriate pressure on the working pulley. The tension pulley is pressed against the outer side of the slack side. The latter causes the belt to undergo reverse bending, which may reduce its lifespan. This type of device is commonly used in drives where an increased wrap angle is needed or space is limited.

How to Follow Traffic on a Slope During Congestion?

Here are the methods for following traffic on a slope during congestion: 1. When following traffic uphill, the first thing to note is maintaining a safe distance from the vehicle in front. This prevents rear-end collisions caused by sudden acceleration. Also, be cautious to avoid rolling back. Solutions include either firmly pressing the brake pedal or pulling the handbrake tight. As long as the vehicle is in good condition, there's generally no need to worry. 2. Manual transmission vehicles require special attention to stalling. Experienced drivers start on a slope by pressing the brake without using the handbrake. To start, press the clutch, shift into first gear, and when releasing the clutch, quickly release the brake and press the accelerator. 3. For beginners, follow the method taught in driving school: slowly release the clutch until about halfway, when you feel the car noticeably shaking and about to stall. At this point, release the handbrake and the brake (preferably with a bit of accelerator), and the car will slowly climb up. 4. Nowadays, many vehicles are equipped with a hill-start assist system. Simply put, this system automatically holds the brakes during hill starts to prevent the car from rolling back and causing accidents. It also allows the driver to easily switch from the brake pedal to the accelerator without feeling flustered.

How Should the Driver Handle a Rear Tire Blowout?

Here are the steps to handle a tire blowout while driving: 1. Maintain straight-line driving. If the front tire bursts, the car body will suddenly tilt to one side, and the vehicle direction will deviate or sway. At this time, the driver should not panic but firmly hold the steering wheel with both hands to keep the car moving straight. 2. Adjust the car direction gently. When turning the steering wheel, the movements should be gentle, avoiding repeated sharp turns. 3. Slow down gradually. When decelerating, first release the throttle while keeping the gear engaged. When the car's posture is under control, downshift step by step and repeatedly apply light brake pressure to bring the car to a slow stop. 4. Turn on the warning lights. Once the situation stabilizes, activate the turn signals or parking warning lights and allow the car to come to a gentle stop.

Do You Need to Step on the Brake When Starting an Automatic Car?

When starting an automatic car in a stationary position, you do not need to step on the brake. However, if the car is about to move, you need to step on the brake. 1. Stationary Start In this state, the car is usually in the "P" gear, which provides braking force. Therefore, you don't need to step on the brake when starting the car. However, from a safety perspective, stepping on the brake while starting is a good habit. 2. Starting to Move When starting the car at a traffic light or preparing to move, you need to step on the brake. In this situation, the car requires power, and most automatic cars have a lock when shifting from "P" to "R" or "N" gear. You must step on the brake to successfully shift gears. Therefore, you need to step on the brake first when starting the car.

How to Deal with Paint Spots on a Car?

Methods for removing paint spots from a car are as follows: 1. Use banana oil for cleaning: Banana oil, also known as thinner. Banana oil can be used to dilute paint and has a good cleaning effect on paint spots. It is generally available at paint stores, but be aware of its flammable, explosive, toxic, and volatile properties. Banana oil can corrode the paint surface, so it must not be used on the paint surface, but it is safe to use on car glass. 2. Use gasoline for cleaning: Gasoline, a well-known cleaning agent, is essentially equivalent to banana oil in nature. It has a good cleaning effect and does not have the strong corrosive properties of banana oil. It can be applied by wiping with a damp towel. 3. Use essential balm for cleaning: Car owners can use essential balm to remove adhered paint. 4. Use fine sandpaper or a blade to remove: Fine sandpaper, blades, etc., can also remove paint spots with careful operation, but there is a risk of scratching the paint surface. If the scratches are minor, they can be repaired by waxing and polishing without affecting the appearance.
