Is It Necessary to Replace Coolant When Changing the Radiator?
1 Answers
Replacing the radiator necessitates changing the coolant. When replacing, drain the old fluid completely, clean the cooling system thoroughly, and then refill it with new coolant. How to Replace Coolant: Before performing a complete coolant replacement, conduct a comprehensive inspection to check for any signs of leaks or cracks in the pipelines, with particular attention to the five-way hose. Coolant flows through the five-way hose and is distributed to different parts of the vehicle to function. If there is any leakage of coolant in this section, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add water to the coolant reservoir and continue filling until clean water circulates continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to allow the water to circulate. Initially, the water draining from the reservoir may appear slightly pinkish. 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. 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 air is purged from the cooling system, the fluid level will drop. Top up the coolant until it reaches the "MAXT" mark on the reservoir.
