How Often Should the Coolant in a Buick Excelle Be Replaced?
1 Answers
Generally, the coolant in a Buick Excelle should 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 pipes, with particular attention to the five-way hose. The five-way hose gets its name from having five connections to various parts, and the coolant is distributed to different sections of the car after flowing through it. If there is any leakage of coolant in this area, the hose or connections should be replaced or resealed as necessary. Drain the old coolant, then flush the fluid channels with clean water. Add 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 have a faint pink tint. Continue adding clean water until the outflow is clear. Remember to disconnect 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 to allow it to flow quickly into the radiator. Then, pour another container of coolant into the 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. Top it up again until it reaches the maximum mark "MAXT" on the reservoir.
