How Often Should the Coolant in Geely Emgrand Be Replaced?
1 Answers
Geely Emgrand coolant generally needs to be replaced every two years or 40,000 kilometers. For vehicles that operate for extended periods, such as taxis, high-quality coolant should typically be replaced annually. To prevent excessive foaming, which can reduce the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolant can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, it should be replaced promptly, and the system should be cleaned. How to Replace Coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any leaks or cracks in the pipes, with particular attention to the five-way hose. Coolant flows through the five-way hose and is distributed to various parts of the vehicle to perform its function. If there are signs of coolant leakage 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. 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 is clear. Note: Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, add 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. As some air is expelled from the cooling system, the coolant level will drop slightly. Top up the coolant until it reaches the "MAXT" mark on the reservoir.
