How to Replace Coolant in Volkswagen Tiguan?
1 Answers
Volkswagen Tiguan Coolant Replacement Method: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines. Pay special attention to the five-way hose, which gets its name from the five connections it has to different parts of the car. The coolant flows through this hose and is distributed to various parts of the vehicle to perform its function. If there are signs of coolant leakage in this area, replace the hose or re-secure 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 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 may appear slightly pinkish. Continue flushing with clean water until the drained water runs clear. Remember to disconnect the heater hose to drain all 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, fill the coolant reservoir with another batch of coolant until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the coolant level will drop. Top it up again until it reaches the "MAXT" mark on the reservoir.
