When the large reservoir is filled to approximately 4kg and the small reservoir to around 2kg, start the engine and turn on the heater to expel any moisture and air. While keeping the engine running, continue adding coolant until it reaches the normal operating level. Do not add the coolant too quickly. Monitor the process dynamically while filling to prevent spills or leaks.

Why Does a Car Always Have Electricity?

Generally, a car only uses the electricity from the battery during the starting phase. Once the engine is running, whether the vehicle is idling or in motion, the generator remains operational, continuously charging the battery. Precautions for using a car battery are as follows: Keep it clean: Maintain the battery clean and dry, ensuring the vent holes are unobstructed. If oxides appear on the plates or terminals, clean them and apply a small amount of grease to prevent corrosion. Avoid continuous use of the starter: Each use should not exceed 5 seconds, with a 10~15-second break between two starts. In severe winter, the battery discharge level should not exceed 25%, and in summer, it should not exceed 50%. Regular charging: A battery filled with electrolyte should not be left in a state of insufficient charge for long periods. Regular charging is necessary; otherwise, it may lead to battery failure. Charging standards: When charging the battery, the voltage should not be too low or too high. Typically, the standard charging voltage for a 12V battery is within the range of (13.5~14.5)V, and for a 24V battery, it is within (28~29.9)V.
