How Many Liters of Antifreeze Should Be Added?
2 Answers
Antifreeze should be added in 5 to 6 liters, divided into two steps. The first step is when the vehicle is static: add the antifreeze while squeezing the rubber tube by hand until the liquid level reaches between Low and High. The second step is after starting the vehicle and driving a certain distance. Observe if the antifreeze level drops. If it does, stop the vehicle and wait for the engine to cool down before adding more antifreeze until it reaches the same level as in the first step. Antifreeze is generally divided into three types: ethanol-water, glycerol-water, and ethylene glycol-water. Ethanol has a freezing point of -114°C and a boiling point of 78.3°C. Ethanol is flammable and evaporates easily, so its content in the mixture should generally not exceed 40%, and it is not suitable for use in diesel engine cooling systems with higher operating temperatures.
The amount of antifreeze actually varies from car to car, so you can't generalize about how many liters to add. My suggestion is that the quickest way is to check your owner's manual, which specifies the exact capacity. Generally, 4 to 5 liters is enough for small cars, while larger vehicles like SUVs may require 6 to 8 liters. When adding, make sure the engine is cooled before opening the cap to avoid being injured by hot liquid spraying out. The liquid level should be between the min and max lines—don't overfill or underfill. Too much can cause expansion and overflow, dirtying the engine compartment, while too little may lead to engine overheating and damage. Also, ensure the colors match, as mixing different antifreeze types can corrode pipes and cause rust. Check the fluid level regularly—if it appears cloudy or drops rapidly, there might be a leak or it's time for a replacement. Replacing it every two years is ideal for keeping your car safe and worry-free.
