Should the Coolant Be Replaced After Changing the Water Pump?
1 Answers
Replacing the coolant is necessary after changing the water pump because the coolant must be drained during the water pump replacement. Method for replacing the coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way hose. The five-way hose gets its name from having five connections to different parts of the vehicle. The coolant flows through the five-way hose and is distributed to various parts of the car to perform its function. If there is any leakage of coolant in this section, the hose should be replaced or the connections should be re-secured 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 it until the water 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 appear slightly pinkish. Continue adding clean water until the water runs clear. Note: Do not 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. This method allows the coolant 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.
