Generally, 5 to 6 liters of coolant should be added. Here is some relevant information: 1. Antifreeze: Antifreeze is a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder head. Antifreeze is not only used in winter but should be used all year round. 2. Do not mix antifreeze: Different manufacturers produce antifreeze with different internal additives. Mixing them could lead to chemical reactions that may damage the cooling system. Therefore, when adding antifreeze, it is best to completely drain the old antifreeze before adding the new one.

There's no fixed amount for how much coolant to add—it depends on the specific car model and engine size. Generally, small car systems hold around 5-10 liters, but don't just blindly fill it up. Last time I worked on my old car, the manual said it could take 7 liters, but when actually adding, it's best to check the dipstick when the engine is cold. Only add small amounts if it's at the low mark, no more than 1 liter at a time to avoid issues. Remember to buy the same type of coolant—don't mix different kinds, or you might clog the cooling system. Add a bit more in cold weather for freeze and burst protection, and in hot weather to prevent overheating. Regular maintenance can save you a lot on repair costs.

I think the coolant refill amount shouldn't be rigidly fixed, as it varies for each vehicle. Most family cars' entire cooling systems hold between 6-8 liters when completely filled, but don't top it off during routine top-ups - just follow the level markings: check with the engine cold by opening the cap, add half a liter if it's at the minimum line, then recheck after a few drives. Always use the specified coolant type, never substitute with tap water as it causes rust. Regular inspections can prevent leaks or overheating issues, especially checking before long trips for added safety to avoid annoying breakdowns on the road.

Generally, adding around 5 liters of coolant is within the normal range for cars, but you should check your vehicle's manual for specifics. I prefer to check the coolant level with the engine cold and the cap off, topping up about half to one liter if it's low—avoid pouring it all at once to prevent overfilling. Pay attention to the coolant mixture ratio and buy brands that match your car to avoid corroding the pipes. Regular maintenance saves hassle and extends engine life.

The amount of coolant to add varies by vehicle, typically ranging from 5 to 10 liters in system capacity. I believe the key lies in prevention: always check the fluid level when the engine is cold, with safety as the top priority. If the level is low, add a small amount, such as 0.5 to 1 liter, gradually to avoid overflow or corrosion. Always use the same type of coolant and avoid mixing different kinds, as it protects against freezing and boiling. Pay extra attention during summer and winter, especially for older cars that have been driven for several years. Check the coolant level monthly to maintain the efficiency of the entire cooling system.
