Engine leak detector spray G 001 800 A1
Notes:
The vacuum in the intake system will cause the
leak detector spray to be drawn in with outside
air. The leak detector spray reduces the
ignitability of the mixture. This leads to a drop in
engine speed and to a significant increase of
the CO content.
Observe safety precautions listed on the
container.
