Golf 4 How to Replace the Warm Air Tank

1. Stop the car and turn off the engine. When the coolant temperature drops, open the expansion kettle and fill it with water tank cleaner.

2. Start the engine until the cooling fan works, and then idle for 5- 10 minutes.

3. Turn off the engine and remove the front bumper of the vehicle. When disassembling, make sure that all fixing screws have been unscrewed, and then slowly disassemble from both ends to the middle. Do not break the fixing buckle.

4. Ensure that the coolant temperature is completely cooled, then discharge the tank cleaner together with the coolant, and finally replace it with a new engine coolant.
