Checking Pressure
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.
- Connect filling point low pressure side (blue hose) to service valve.
- Start the engine and allow to run 1500-1600 RPM.
- Place blower fan switch in the lowest active manual position.
- Place air conditioning (A/C) switch to on.
- Place REC-switch to on.
Check that the compressor switches in and out within the specified values:
The compressor should switch to at 295-325 kPa (42.8 - 47.1 psi).
The compressor should switch out at 150-170 kPa (21.8 - 24.7 psi).
Does the compressor switch in and out at the specified values?
- YES
Refer to Fault-Tracing Information
- NO
- Connect filling point low pressure side (blue hose) to service valve.
- Start the engine and allow to run 1500-1600 RPM.
- Place blower fan switch in the lowest active manual position.
- Place air conditioning (A/C) switch to on.
- Place REC-switch to on.
Check that the compressor switches in and out within the specified values:
The compressor should switch to at 295-325 kPa (42.8 - 47.1 psi).
The compressor should switch out at 150-170 kPa (21.8 - 24.7 psi).
The following alternatives are available:
- The compressor runs constantly above 325 kPa (47.1 psi). Refer to Checking A Missing Component .
- The compressor switches on too high (above 325 kPa (47.1 psi)), or off too low (under 150 kPa (21.8 psi)). Refer to Replacing Component .
- The compressor switches in and out within the specified values. Refer to Checking For Leakage .
- The compressor switches in and out within the specified values, but is shut off for a long period of time. Refer to Checking Blocked Expansion Pipe .
