•

Use a water/soap emulsion for carrying out the leak test.

The following fluid mixture makes an ideal water emulsion: 6 drops of commercially available
soap mixed in 1 liter of tap water.

•

Fill a spray bottle with soapy water.

•

It can take up to 2 minutes to detect a possible leak indicated by air bubbles, depending on the
vehicle.

•

The leak test involves blowing in compressed air. To do this, the compressed air must be set to
max. 8 bar at the pressure reducer for the compressed air supply.
