Where to Add Antifreeze in Audi Q7?
1 Answers
Method for replacing antifreeze: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze. 2. Insert a rubber hose connected to a tap into the radiator filler port, turn on the tap to allow tap water to continuously flow through the engine cooling system. During the flushing process, keep the engine idling and continue the operation until clear water flows out of the radiator. 3. Turn off the tap, wait until all the water in the cooling system is drained, then close the radiator drain valve. 4. Add antifreeze from the radiator filler port until the radiator is full. Unscrew the reservoir cap, add antifreeze up to the "Max" mark, being careful not to exceed it. 5. Replace and tighten the radiator cap and reservoir cap.
