Draining refrigerant

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

To empty the system the ambient temperature should be above 20°C. Running the engine a short time (five minutes) before starting work will speed up the draining process.

Drain at the service valve.
The A/C system will empty in approximately 25 minutes.
Check the amount of oil (if any) that has run out when draining the refrigerant.

NOTE:

When fault-tracing:

There are no high/low pressure connections on the compressor. Thus is it only possible to check the operation of the low pressure switch (Pressostat). Connecting to the service valve.
