Antifreeze level decreases after some time of use because the engine's operating temperature is too high, causing some of the antifreeze to evaporate. It could also be due to cracks in the cylinder head gasket or cylinder block, allowing antifreeze to enter the engine and burn off. Another possibility is a leak in the cooling system, causing continuous antifreeze loss. When this happens, it's essential to check what is causing the antifreeze to decrease and repair the issue once the cause is identified. The full name of antifreeze is antifreeze coolant, and its primary function is not to prevent freezing but to cool the engine. When the engine is running, the antifreeze continuously circulates within the engine to dissipate excess heat, ensuring the engine operates within a reasonable temperature range.

Why Does the Brake Become Hard and the Car Won't Start?

Reasons why the brake becomes hard and the car won't start: 1. Dead battery: This may be caused by leaving the headlights on for an extended period, resulting in a drained battery, or the battery may have reached the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit malfunctions. 2. Lack of antifreeze: Some car owners use water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions, leading to engine block cracks. This prevents the car's water pump from functioning, making it impossible to start the engine and potentially damaging other engine components. 3. Wrong gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) when starting. If the gear is left in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars also won't start if the clutch is not depressed.

Can a Modified Grille Pass the Annual Inspection?

After the implementation of the "Motor Vehicle Inspection Work Regulations (GA801-2019)", grille modifications that comply with the regulations can pass the annual inspection. Compliance with the regulations means that the length and width of the vehicle body do not change after the grille modification. Generally, the grille does not alter the vehicle's width, but changes in the vehicle's length are more likely to occur and require attention. When replacing the grille, the following issues need to be considered: 1. Ensure air circulation in the engine compartment: Guarantee that the engine can smoothly intake air and provide cooling for the radiator, intercooler, and condenser. 2. Protect the engine: The grille must serve to protect the engine. In poor road conditions, a grille with good impact resistance can give the owner more peace of mind.

Is it allowed to drive without a spare tire?

Driving a car without a spare tire is not a violation of regulations, as there are no relevant traffic laws requiring a spare tire for road use. Below is relevant information about spare tires: 1. Full-size spare tire: Compared to non-full-size spare tires, full-size spare tires are more reliable, with the same tire width as regular tires. 2. Non-full-size spare tire: The driving speed with a non-full-size spare tire should not exceed 80 kilometers per hour. 3. Run-flat tires: These serve the same purpose as spare tires and are safer than regular tires. They allow driving up to approximately 80 kilometers at a maximum speed of 80 km/h after a tire blowout, providing sufficient distance to reach the nearest service center for repairs.

Do Leather Seats Need Seat Covers?

Leather seats do not require seat covers. The specific reasons are: 1. Stain resistance: Leather seats are more stain-resistant than regular fabric seats, and common dust and stains can be easily wiped off with a clean cloth. 2. Safety impact: Seat covers can interfere with the deployment of side airbags, affecting the safety functions of the seats to varying degrees. 3. Poor ventilation: A drawback of leather seats is their lack of breathability, and adding seat covers can make them even less breathable, shortening the lifespan of the leather seats. 4. Low environmental friendliness: Most seat covers have an odor, and when temperatures rise, more odor molecules are released into the air, making the smell stronger.

Otherwise, it may cause damage to the wiper motor. Additional Information: Types of Windshield Wipers: 1. Traditional Intermittent: This is the most common type of wiper, with three to four settings, allowing the driver to adjust based on rain intensity and visibility. 2. Rain-Sensing: This type is increasingly used in mid-to-high-end vehicles in recent years. It features heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, close fit to the windshield, reduced motor load, low noise, strong water repellency, and soft material that won't scratch the windshield, ensuring clear visibility.
