Draining the coolant
Note. To drain the system the ambient temperature should be higher than 20°C (68°F). If the engine is left running for a while (five minutes) before draining, the draining will be faster.
Scheme 315
- Draining is done via the service valve on the front
- The A/C system is drained in approximately 25 minutes
- Check for oil which may have run out when draining the coolant.
Note. When trouble-shooting: There are no high-pressure/low-pressure connections on the compressor. Therefore it is only possible to check if the pressure sensor works. Connection on vehicle service valve.
