Volkswagen Golf Service & Repair Manual / Air conditioning system with refrigerant R134a / General information on refrigerant circuit / Evacuation and charging valves for quick-release couplings of air conditioner service station on refrigerant circuit

Special tools and workshop equipment required
Torque wrench -V.A.G 1783- (2…10 Nm) with 1/4" ratchet adapter -VAS 6234-
  WARNING
Danger of freezing injuries.
If refrigerant circuit has not been evacuated, refrigerant will escape.
Extract refrigerant before opening refrigerant circuit. If the refrigerant circuit is not opened within 10 minutes after it has been evacuated, pressure may develop in coolant circuit due to re-evaporation. Extract refrigerant again.
Only valves and connections resistant to R134a refrigerant and the related refrigerant oils may be used.
The connectors for the high-pressure and low-pressure sides are different (outside diameter).
Always screw on sealing caps.
Arrangement within the vehicle.
