How Often Should the Coolant in a Buick Excelle Be Replaced?
1 Answers
Buick Excelle coolant generally needs to be replaced every two years or approximately 40,000 kilometers. Before completely replacing the coolant, a thorough inspection should be conducted to check for any signs of leakage or cracks in the pipelines. The focus should be on inspecting the five-way water pipe, which gets its name from having five connecting interfaces to different parts. The coolant flows through the five-way pipe and is then distributed to various parts of the car to function. If there is any coolant leakage in this section, the water pipe should be replaced or the interface re-secured as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue adding water to the reservoir so that it continuously flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Don’t forget to remove the heater hose and drain the water from the heater core. About an hour after draining, add the new coolant through the radiator hose—this is the quickest way to get the coolant into the radiator. Then, add another container of coolant to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as some air is expelled from the cooling system. Top up the coolant again until it reaches the "MAXT" mark on the reservoir.
