Idling with the air conditioning on can cause certain damage to the vehicle and wear to the engine, potentially requiring shorter maintenance intervals. If the engine speed is too low to support the air conditioning, incomplete combustion may occur, leading to carbon buildup. Additionally, idling with the air conditioning on can result in poor system cooling, making it easy for the engine to overheat. Precautions for using car air conditioning are as follows: 1. Note 1: The refrigerant continuously expands and absorbs heat in the evaporator, cooling it. The cooled evaporator then cools the air blown by the fan, allowing the car's air conditioning vents to blow cold air. 2. Note 2: The refrigerant used in car air conditioning is R134a. The car air conditioning system requires regular refrigerant top-ups. Prolonged failure to add refrigerant can lead to reduced cooling efficiency and slower cooling speeds. 3. Note 3: Regular cleaning of the car air conditioning system is essential. Otherwise, bacteria can proliferate inside the system. When cleaning the air conditioning or adding refrigerant, always visit a professional service center where experts can perform the task using specialized equipment.

How to Check the Manufacturing Year of Car Glass?

There are two methods to check the manufacturing year of car glass: 1. Number + Dots Format: The number indicates the year, and the dots represent the month. If the dots are in front of the number, it indicates the first half of the year. Subtract the number of dots before the digit from 7 to get the month in the first half. If the dots are behind the number, it indicates the second half of the year. Subtract the number of dots after the digit from 13 to get the month in the second half. This method applies to 80% of vehicle glass on the market. 2. Number + Small Dots + Large Dots Format: The number represents the year, small dots represent the quarter (maximum of 4 small dots for 4 quarters in a year), and large dots represent the month within the quarter (maximum of 3 large dots for 3 months in a quarter).
