What are the reasons for coolant leakage?

The reasons for coolant leakage include: 1. Sealing issues in the cooling system: The connection between the coolant reservoir and the radiator is not tightly sealed, leading to coolant leakage; 2. Pipe problems: Aging or cracked rubber pipes cause coolant leakage; 3. Radiator issues: Corrosion of the radiator results in coolant leakage. The main areas where coolant leaks occur are around the radiator. You can check the exterior of the radiator and the pipe connections for any signs of liquid. Significant coolant leakage will cause the engine temperature to rise, and the car's dashboard will display a temperature warning. It is advisable to inspect and repair the issue as soon as possible to prevent damage. Coolant, also known as antifreeze coolant, primarily functions to prevent freezing, cool the engine, resist corrosion, and prevent scaling. Coolant is colored to distinguish it from other liquids, making leaks easier to detect.

Do New Cars Need Gasoline Additives?

New cars do not require gasoline additives. The main functions of gasoline additives are: 1. Cleaning carbon deposits: Carbon deposits are byproducts of incomplete gasoline combustion and are particularly severe in direct-injection engine models. Severe carbon buildup in engine cylinders may cause abnormal engine vibrations, increased fuel consumption, and reduced power. 2. Engine maintenance: Reducing carbon deposits in the engine to ensure normal operation. Although gasoline additives do have certain benefits, new car engines are in good working condition with minimal usage time, so carbon deposits are unlikely to accumulate. Additionally, fuel from gas stations is already required to contain a certain amount of gasoline additives, making it unnecessary to add extra for new cars.

Where to Place the ETC on the Windshield?

The installation position of the ETC for small cars is generally in the upper middle part of the windshield horizontally, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters in height, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or later-added anti-explosion films, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave skylight zone. Here are the precautions for ETC installation: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large backward tilt angle, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power, but generally, it does not need to be charged or have its battery replaced because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may easily block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Notes for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic payment for the vehicle ahead. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to payment failure. When using a debit card to bind with ETC, insufficient balance will also cause payment failure.

What does the N gear in an automatic transmission car mean?

The N gear in an automatic transmission car stands for Neutral, which can be used during startup, when parking without leaving the vehicle, or when towing. When the gear lever is in this position, the transmission idles, and the engine power cannot be transmitted to the drive wheels, having no driving or restraining effect on the wheels. It is not advisable to coast in Neutral (N gear) in an automatic transmission car. Some drivers shift to N gear while driving at high speeds or going downhill to save fuel, but this can damage the transmission. You can shift to N gear when waiting at traffic lights or for parking stops longer than 30 seconds, aiming to cut off the power transmission between the input and output shafts inside the transmission. If parked on a slope, remember to press the brake or engage the electronic handbrake to prevent the car from rolling.

What is the speed limit for small cars on highways?

Highway speed limit for small cars is 120 kilometers per hour. When driving normally on highways, the minimum speed for motor vehicles should not be lower than 60 km/h. Small passenger vehicles must not exceed 120 km/h at maximum speed, while large buses and trucks must not exceed 90 km/h, and motorcycles must not exceed 80 km/h and are prohibited from carrying passengers. When the speed displayed on traffic signs or road signs differs from the above regulations, the signs or markings should be followed. Highways are multi-lane roads exclusively designed for directional and lane-separated vehicle traffic with full access control. The annual average daily traffic volume for highway design should exceed 15,000 passenger car equivalents, with a design speed ranging from 80 to 120 kilometers per hour.
