How many liters of antifreeze are generally needed?
2 Answers
Generally, 6-7L is required. Antifreeze, also known as antifreeze coolant, refers to a coolant with antifreeze functionality. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. How to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; promptly add antifreeze. Check the water level markings on the antifreeze bottle. The antifreeze level should normally be between the maximum and minimum marks. To determine if antifreeze is low, observe the markings. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
Last time I went to change the coolant for our family SUV, the mechanic said it needed 6 to 8 liters. Actually, the amount varies quite a bit between different models - generally 4 to 6 liters is enough for compact cars, while larger SUVs or pickup trucks require more. It's best to check the vehicle manual first since that gives the accurate specification. When I had it changed at the dealership, they used professional equipment to completely drain the old fluid before adding new coolant, and the actual amount used was about the 8 liters specified in the manual. A reminder to everyone: don't randomly top it up yourself. Coolants come in different colors, and mixing them can corrode the pipes. After refilling, have the mechanic check for leaks in the system, then start the engine to circulate the coolant and verify the fluid level - this is crucial since it directly affects engine lifespan.
