How to Replace Coolant for Cruze?

[Lee]

To replace the coolant for Cruze, follow these steps: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a special focus on the five-way water pipe. The five-way pipe is named for its five connecting interfaces to various parts. Coolant flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any coolant leakage in this section, replace the water pipe or re-secure the interface as needed. Drain the old coolant and 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. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir will appear slightly pinkish. Continue adding clean water until the drained water runs clear. Note: Remember to remove the heater hose and drain all water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, add another container of coolant to the 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 expelled from the cooling system. Add more coolant until it reaches the "MAXT" mark on the reservoir.
