How Much Antifreeze Is Needed to Fill Up?
2 Answers
It takes 6 to 7 liters to fill up the antifreeze. Here are detailed methods to determine whether the antifreeze is sufficient: 1. Check the antifreeze warning light on the dashboard; 2. Observe the fluid level in the reservoir. Antifreeze, also known as coolant, prevents the cooling liquid from freezing in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Antifreeze offers multiple benefits, including freeze protection in winter, boil-over prevention in summer, and year-round protection against scale and corrosion. Here are detailed guidelines on how to choose the appropriate antifreeze: 1. Select the freezing point based on the ambient temperature conditions of the vehicle's operating environment. The antifreeze grade corresponds to its freezing point, which should be approximately 10 degrees lower than the lowest winter temperature in the local area; 2. Key selection criteria include rust prevention, corrosion resistance, and descaling functions.
Last time I helped my dad change the coolant, I realized there's quite a bit to it. My Corolla takes over 5 liters for a refill, but my neighbor's SUV needed nearly 8 liters to fill up. It mainly depends on the cooling system design - most sedans require 4-6 liters. Remember to do it when the engine is cold - slowly add coolant after unscrewing the expansion tank cap, filling to between the MAX and MIN marks is safest. Once I got lazy and poured too much, and when the engine heated up, the coolant sprayed out from the overflow tube, leaving a sticky mess in the engine bay that took me half an hour to clean. Later I learned my lesson - after filling, let the engine run for ten minutes before checking the level and topping up - that's the most accurate way.
