Seat Leon >> Removing and fitting the evaporator

WARNING

Danger from refrigerant escaping under pressure! Freezing of skin and other body parts.

  • Evacuate the refrigerant and then open the refrigerant circuit immediately.
  • If more than 10 minutes have elapsed since evacuation and the coolant circuit has not been opened, evacuate the refrigerant again. Pressure builds up in the coolant circuit as a result of secondary evaporation.
