What is the method for bleeding air from a car radiator?

Car radiator air bleeding method is to start the engine and let it warm up. Wait until the electric fan turns on and the coolant level drops, then top up the coolant and close the radiator cap. The car radiator, also known as the heat exchanger, is a key component in the automotive cooling system. Its function is to dissipate heat - the coolant absorbs heat in the water jacket, flows to the radiator to release the heat, then returns to the water jacket in a continuous cycle, achieving temperature regulation. Car radiator maintenance methods include: 1. Preventing engine overheating; 2. Immediately stopping and opening the engine hood for cooling if smoke appears from the radiator; 3. Regularly replacing coolant; 4. Never using tap water as a substitute for coolant; 5. Periodically cleaning the radiator to remove rust and scale deposits.
Having air in the radiator is no small matter, as it can easily cause engine overheating. Let me teach you a practical method: First, wait until the car has completely cooled down and park it on level ground, then open the radiator cap—be very careful not to burn yourself. Start the engine and let it idle while you observe the coolant level; you'll see small bubbles slowly rising. When the temperature gauge reaches the midpoint, add some distilled water to keep the level near the MAX line. After securing the cap, take a 20-minute drive to let the cooling system circulate and expel the air. Check the coolant level again when you get home, and top it up with coolant if it's low. Remember, never open the cap when the engine is hot—the steam that shoots out is no joke.
