Why Should Coolant Be Replaced?
1 Answers
During long-term use, coolant inevitably deteriorates, leading to reduced performance in functions such as antifreeze and cooling. Additionally, failure to replace the coolant can cause corrosion of the car's metal pipes and even lead to radiator corrosion and leaks. The method for replacing coolant is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with particular attention to the five-way water pipe. Coolant flows through the five-way pipe and is then distributed to different parts of the car to perform its functions. If there are signs of coolant leakage in this section, replace the water pipe or reseal the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continuously inject water into the reservoir so that it 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 may have a faint pink tint. Continue adding clean water until the outflow is clear. Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, add the new coolant through the radiator hose. 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. During this time, the coolant level will drop slightly as air is purged from the cooling system. Add more coolant until the reservoir reaches the maximum mark "MAXT".
