Can I Change the Antifreeze Myself?

[StPatrick]

You can change the antifreeze yourself. The specific steps are as follows: 1. Before replacing the antifreeze, ensure the car is in a cold state. Open the radiator drain valve to drain the antifreeze. 2. Pour in clean water and keep the engine idling until the water coming out of the radiator is clear. 3. Wait for all the water to drain, then close the drain valve and the engine. Add new antifreeze until the liquid level is between the max and min marks. 4. After idling the engine for two to three minutes, the antifreeze level may drop slightly. At this point, top it up to the appropriate level again. Antifreeze, also known as antifreeze coolant, is a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head.
