SANDEN
compressors come with refrigerant oil already installed.
Some Land Rover Discovery and Range Rover Sport are built with the same air conditioning compressor. The Original
Equipment Manufacturer Numbers (OEM numbers) are Land Rover 9X23-19D629-DA.
The air-conditioning system of these vehicles was assembled with a
Sanden PXE16 compressor. Manufacturer numbers: Sanden 1656, 1656P.
These
ac units seem to be interchangeable.
