How much antifreeze should be added to a car?
2 Answers
The amount of antifreeze added to a car should be between the max and min levels, which can be checked at the antifreeze filler port. It is recommended to replace the antifreeze every 2 years, with a replacement volume of 4 to 5 liters. After replacement, the cooling system should be purged. Using antifreeze can effectively reduce the corrosion of the coolant on the engine, prevent scale formation, and extend the service life of the cooling system. Antifreeze is added to the car's radiator, also known as the heat exchanger, which is a key component of the car's cooling system. Its function is to dissipate heat: the coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to complete the temperature regulation cycle. It is an integral part of the car's engine.
I've been driving for over a decade, and when it comes to coolant, I believe the quantity depends on the vehicle model. Each car's cooling system has a different capacity - new cars may hold four to five liters, but you should check your owner's manual or ask the dealership for specifics. I regularly check the level in the expansion tank, which has Min and Max markers - I fill it to near the Max line and stop there, never exceeding it. Overfilling can cause the fluid to expand and leak, corrode components, or even damage the engine. Coolant isn't just for winter; it also prevents boiling and rust in summer. I check the level every six months and top it up if low, but always using the manufacturer-recommended 50/50 premixed solution. If you're unsure, have a professional mechanic check it to avoid unnecessary repair costs.
