System Compressor and Oil
Handling
Installation of the Compressor
The compressor(s) is mounted on the under side of the engine. The side to side
mounting of the compressor must remain 45 degrees from the horizontal. The
forward and backward angle should be 10 degrees of horizontal. Access to the
air conditioning service ports is under t he driver’s side midway of the vehicle.
Each compressor comes with a standard charge of 5 oz. of PAG compressor oil.
This quantity of oil is enough to install the compressor on a system that has oil
already in it. New systems require that the proper amount of oil be added to the
system.
During normal operation of the system, there is always oil traveling throughout
the system. The oil lubricates all the components in the systems and returns
back to the compressor, and then back into the system.
Major Loss or Refrigerant
In a major refrigerant leak, we can assume that a fair amount of oil will be lost in
the system. The oil level should be verified by following the next steps (checking
compressor oil level).
Checking the Oil Level
Remove the compressor, and drain the oil by removing the drain plug and from
the other ports. Cycle the compressor cylinders by turning the clutch by hand,
and drain the oil again. Repeat until all the oil is drained from the compressor.
Measure the oil in liquid ounces, also, inspect the oil for contamination.
