How many liters of coolant does a BMW X1 need?

The BMW X1 requires 5.5 to 6 liters of coolant. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It offers excellent performance characteristics such as freeze protection in winter, boil-over prevention in summer, and year-round protection against scale and corrosion. How to replace coolant: Before completely replacing the coolant, conduct a thorough inspection to check all pipelines for any signs of leakage or cracks, with particular attention to the five-way water pipe. Coolant is distributed to different parts of the vehicle through this five-way pipe to perform its functions. If there's any coolant leakage in this section, replace the water pipe or resecure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add water to the coolant reservoir and continue filling until clean water circulates continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pinkish. Continue adding clean water until the outflow runs clear. Remember to disconnect the heater hose and drain all water from the heater core. About one hour after draining, add new coolant through the radiator hose. Then, pour another container of coolant into the reservoir until it's nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the fluid level will drop slightly. Add more coolant until it reaches the "MAXT" mark on the reservoir.
I have experience with adding coolant to the BMW X1. My car has been running for several years, and generally, it requires about 6 to 7 liters, depending on the engine model and year. My own 2.0T model needs approximately 6.5 liters. Coolant isn't something you just add casually; its role is to prevent freezing, overheating, and protect the engine from rust. If the level is too low, you can temporarily top it up with distilled water, but don't use it as a long-term substitute—it's best to use the original coolant that matches the color. I change mine every two years to avoid corrosion in the system. Checking it yourself is simple: when the engine is cold, open the hood and ensure the level in the reservoir is between the min and max lines. If you notice frequent leaks, get it fixed promptly to avoid engine overheating and potential breakdowns. From discussions in car owner groups, climate in different regions also affects the amount needed.
