How Much Antifreeze Should Be Added to a Car?
2 Answers
Generally, the antifreeze reservoir will have a max (maximum) water level mark and a min (minimum) water level mark. The car antifreeze should be added to a level between the max and min marks. Typically, family cars require 4-6 liters of antifreeze for a change, depending on the vehicle. Methods 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, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level marks on the antifreeze reservoir. The antifreeze level should normally be between the maximum and minimum marks. To determine if antifreeze is low, observe the marks. If the antifreeze is below the minimum mark, it indicates a shortage of antifreeze.
I drive quite often, and I remember one time when I was adding coolant in a fluster and filled the expansion tank to the brim. As a result, the engine overheated halfway and triggered a warning alarm. It cost me over 500 yuan to fix it. Since then, I've learned my lesson—now I always check the markings on the tank and only fill it to the midpoint between MIN and MAX, never exceeding or falling short. The expansion tank is usually located under the front hood; just use a wrench to unscrew the cap, and you'll see it. It's best to check it every few months, especially before seasonal changes, as the fluid level naturally evaporates a bit. This simple routine protects the engine and requires little effort. Since making it a habit, my car has had fewer issues, and I feel more at ease while driving.
