How many liters of coolant does the Envision require?

The Envision requires 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 in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. How to replace coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. Coolant is distributed to different parts of the car through the five-way hose to perform its function. If there is any leakage of coolant in this area, replace the hose or resecure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows 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 will have a faint pink tint. Continue adding clean water until the outflowing water is clear. Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose. Then, pour another container of coolant into the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant until it reaches the "MAXT" mark on the reservoir.
I've been driving the Buick Envision for several years. The coolant capacity is generally around 8 to 10 liters, depending on your vehicle's model year and engine displacement. For example, the 1.5T version might be closer to 8 liters, while the 2.0T could reach 10 liters. I remember the manual explains it quite clearly, so I recommend checking your vehicle's owner's manual first. The replacement interval is usually recommended every two years or 30,000 kilometers. Over time, the fluid can degrade and affect engine cooling. I've changed it once myself—you need to use a coolant compatible with Dex-Cool and avoid mixing brands, as it can clog the cooling system. It's best to regularly check the fluid level to ensure it stays between the MIN and MAX marks. If you notice the level dropping quickly, check for leaks and fix them promptly to prevent engine overheating. Such small maintenance tasks can extend your car's lifespan, saving you money and giving you peace of mind.
