Can antifreeze only be used in the winter?

Antifreeze is commonly associated with winter use by many users. However, despite its name, antifreeze serves not only to cool the engine system but also possesses excellent properties such as resistance to low and high temperatures, as well as corrosion prevention. Therefore, it plays a crucial role in the summer as well.

The full name of antifreeze is antifreeze coolant, which is a liquid composed of antifreeze additives and additives that prevent metals from developing rust and corrosion, and water. It needs to be antifreeze, corrosion resistant, thermally conductive and non-deteriorating.

Antifreeze is commonly used in engine cooling systems. It not only prevents freezing in winter, but also helps to cool and prevent heating in summer. It also has the function of preventing water scale and corrosion, providing protection for the engine and cooling system. Its main function is to protect the engine in all weather conditions.

When the cooling system of the engine lacks coolant, the coolant temperature warning light will emit a warning signal. At this point, it is necessary to immediately drive to the side of the road, turn on the hazard lights, stop the car, turn off the engine, and open the engine hood. Check the coolant reservoir in the engine compartment, where there are markings for MAX (maximum) and MIN (minimum). If the coolant level is below the minimum mark, it indicates the need for additional coolant. Add coolant until it reaches the middle of the marked range (wait 5-10 minutes before opening the cap to avoid scalding from steam).

Additionally, it is important to note that different brands or colors of coolant should not be mixed, as it can result in a weakened cooling system and severely affect the normal operation of the engine.

The general replacement cycle for coolant is every 2 years or 40,000 kilometers (whichever comes first). However, in practical use, the replacement cycle may vary for different brands and types of coolant. It is also necessary to consider the specific usage conditions of the vehicle for determining the appropriate replacement schedule.

Furthermore, it is important to note that in regions with low temperatures, it is crucial to select coolant with a lower freezing point. Failure to do so may affect the normal operation of the engine and potentially lead to accidents.
