Sprinter 2500 V6-3.0L DSL Turbo VIN 45 (2007)
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Failure to properly adjust the refrigerant
oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to
the refrigerant system.
NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals
may result in a refrigerant system leak.
NOTE: The A/C liquid line is serviced in three sections.
FRONT SECTION
1. Remove the tape or plugs from the opened refrigerant line fittings and condenser ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto the refrigerant line fittings. Use only the specified O-rings as
