The method to check the date on car glass is as follows: The glass is marked with numbers and black dots indicating the production year and month. The number represents the year, which can be determined based on the vehicle's manufacturing date. The black dots represent the month; if the dots are in front of the number, subtract the number of dots from 7, and if they are behind the number, subtract from 13 to get the month. Some glass may also have a few thick black dots after the production year and month, which are used to specify the week of the month. Relevant information about car glass includes: 1. Introduction: Car glass is an essential part of the vehicle's body accessories, primarily serving a protective function. 2. Classification: Car glass mainly falls into three categories: laminated glass, tempered glass, and zone-tempered glass, which can withstand strong impacts. Car glass is also categorized by its location: front windshield, side window glass, rear windshield, and sunroof glass.

How to Deal with EBD Malfunction?

ebd malfunction handling methods: 1. Reduce vehicle speed; 2. Conduct an inspection when the vehicle is stationary; 3. Turn off the vehicle and let it sit for a few minutes, then restart to check if the malfunction warning persists; 4. Visit a 4S shop or the nearest auto repair shop as soon as possible to have professionals read the fault codes with a computer, identify the issue, and perform targeted repairs. EBD stands for Electronic Brakeforce Distribution system, which ensures balanced braking force between the front and rear axles, prevents tailspin or yaw motion, maintains vehicle stability during braking, optimizes braking efficiency, and significantly reduces braking distance.

What are the symptoms of low automatic transmission fluid?

Automatic transmission fluid low symptoms are: 1. Difficulty starting, when driving in low gear stepping on the accelerator increases RPM but the car has trouble starting; 2. Overheating transmission leading to damage of bearings and gears; 3. Gear shifting feels jerky with unsmooth transitions and abnormal transmission noises; 4. Power loss, when accelerating even if engine RPM rises the car won't speed up and the engine makes loud noises. To avoid transmission fluid shortage, regularly check the transmission dipstick to determine fluid levels. Automatic transmission fluid should be replaced every 2 years or 40,000 kilometers.

What are the differences between 30 and 40 oil viscosity?

40-grade oil has higher viscosity than 30-grade oil. 40-grade oil is suitable for higher maximum temperatures compared to 30-grade oil. 30-grade oil has better fluidity than 40-grade, which can reduce fuel consumption more effectively and dissipate heat from the engine faster. 40-grade oil offers better oil stability under extremely high-temperature conditions in the engine compared to 30-grade. Below are related explanations: 1. Oil grading: The numbers following the oil grade indicate its viscosity specification. For example, in "15W-40, 5W-40," the "W" stands for Winter. The smaller the number before "W," the better the oil's low-temperature fluidity, indicating it can be used in lower environmental temperatures and provides better engine protection during cold starts. For instance, 5W can withstand external temperatures as low as -30°C, while 20W can only withstand -15°C. 2. Letter combinations: Oil grading uses a combination of two letters. The "S" series represents oil for gasoline engines, with specifications ranging from SA to SN (in alphabetical order, but excluding SI). Each subsequent letter indicates improved oil performance over the previous one, with more additives to protect the engine.

What Grade is SN Engine Oil?

SN-grade engine oil is classified as the highest grade of engine oil. Below is relevant information about SN engine oil: 1. Grade of SN engine oil: Engine oils starting with "S" are specifically for gasoline engines, meaning they cannot be used in diesel vehicles. Furthermore, engine oils are divided into twelve grades: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN. With each ascending letter, the performance of the engine oil surpasses the previous grade. 2. Recommendations for using SN engine oil: Although SN-grade engine oil offers the best performance, it is advisable to use the grade specified by the engine manufacturer. However, if the vehicle is frequently driven in congested urban environments, using a higher-grade engine oil can be beneficial (more environmentally friendly and economical).

Can You Drive Without Coolant?

You cannot continue driving without coolant. Here is the relevant introduction to the cooling system: 1. The role of coolant: The function of coolant is to dissipate heat from the engine. Without coolant, the car's engine and radiator lose protection, affecting the heat dissipation of the radiator. The engine temperature will keep rising without effective cooling, and the normal circulation of antifreeze will be disrupted. Continuing to drive under such conditions may cause severe engine damage. In cold climates, it can also lead to the engine or radiator freezing, resulting in engine failure and rendering the vehicle inoperable. 2. The optimal coolant level: The coolant reservoir usually has 'max' (maximum level) and 'min' (minimum level) markings. If the coolant level is below the 'min' mark, it indicates insufficient coolant, and it needs to be replenished promptly. The ideal amount of coolant to add should be between the 'max' and 'min' levels.
