How to Replace Coolant in a Sedan?
1 Answers
Method for replacing coolant in a sedan: 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. The five-way hose gets its name from having five connections to different parts of the car. The coolant flows through the five-way hose and is then distributed to various parts of the vehicle to perform its function. If there are signs of coolant leakage in this section, replace the hose or resecure the connections as needed. Drain the old coolant and then flush the fluid channels with clean water. Add clean water to the coolant reservoir and continue filling the reservoir with water until it 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 may have a faint pink tint. 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. 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 purged from the cooling system. Top up the coolant to the "MAXT" mark on the reservoir.
