One of the reasons why you may need to add engine coolant is because the engine coolant warning comes on. It should not be necessary to add coolant frequently since the cooling system is a closed system.
If you need to add engine coolant regularly or have to add coolant all the time, see an auto mechanic.
- Park the Volkswagen on level ground. Turn off the ignition and set the parking brakes.
- Pull the hood release under the dashboard. Go to the front of the vehicle, release the hood latch, and lift up the hood. Secure the hood with the hood rod or ensure the hood stays up on its own.
- Locate the engine coolant reservoir on the left side and note the circular reservoir with a blue or black cap.
- Check the engine coolant level by looking at the side of the reservoir. Most Volkswagens have a translucent coolant reservoir, and you should be able to check the current engine coolant level without removing the cap but simply by looking at the side of the reservoir.
- If the coolant level is below the MIN level mark, turn the cap counter-clockwise and remove it.
- Add engine coolant. Use the recommended OEM Volkswagen coolant, which for most models is Volkswagen G12 or G13 coolant. The antifreeze/coolant is typically mixed 50/50. Add the necessary coolant to bring the level at or near the maximum.
- Reinstall the lid. Start the vehicle and ensure the engine coolant light is turned off.
If the engine coolant light remains on or the engine is overheating, do not continue to drive. Ensure the vehicle is diagnosed by a mechanic.
What coolant to use on a Volkswagen?
The OEM Volkswagen coolant typically is G12, or G13 VW coolant mixed 50% antifreeze and 50% distilled water.
While you don't have to use Volkswagen coolant, it is required to use coolant that meets the specifications mixed 50/50 with antifreeze and distilled water.
- Warning! The engine may be hot and can potentially cause burns. Allow the engine to cool down before you check or add engine coolant on a VW.
