1. 19 mm socket
2. 19mm wrench
Instructions:
1. Park your car on level ground and ensure the engine is off.
2. Craw underneath the car and find the oil pan drain plug. On the 1.8L Passat, it is a 19 mm bolt. The oil drain plug is located on the bottom of the oil pan, facing downward.
3. Place the oil pan under the drain plug and make sure it is large enough to hold the oil.
4. Use a 19 mm wrench or socket to loosen and remove the oil drain plug. Be careful, as the oil may be hot.
5. Allow all of the oil to drain out into the oil pan. This may take several minutes.
6. Once all the oil has drained out, replace the oil drain plug. Tighten the plug securely using a 19mm wrench or socket.
7. Dispose of the old oil properly. Take the used oil to a recycling center or auto parts store.
