11. Record the compressor discharge pressure. If the reading is higher than the pressure shown in the Compressor
Discharge Pressure Chart, the system could be overcharged. If the reading is equal to, or lower than the pres-
sure shown in the chart, continue with this procedure.

EXAMPLE: The ambient temperature is 21° C (70° F). The evaporator inlet tube temperature is 12° C (54° F) and
the evaporator outlet tube temperature is 10° C (50° F). Subtract the inlet tube temperature from the outlet tube
temperature. The difference is -2° C (-4° F). With a -2° C (-4° F) temperature differential at 21° C (70° F) ambient
temperature, the system is fully charged.
12. Add enough refrigerant to bring the refrigerant system up to a full charge.
13. Remove the jumper wire from the low pressure cycling clutch switch wire harness connector and plug the con-
nector back into the switch.
A/C COMPRESSOR
DESCRIPTION - A/C COMPRESSOR
The Air Conditioning System uses a Nippondenso, double-acting swash plate-type compressor. This compressor
has a fixed displacement of 170 cubic centimeters (10.374 cubic inches). A label identifying the use of R-134a refrig-
erant is located on the underhood fuse panel cover.
The A/C system uses 1.97 Lbs. (0.88 Kg.) of R-134a type refrigerant.
OPERATION - A/C COMPRESSOR
After the Electromagnetic Clutch has produced the frictional connection between the engine and the compressor, the
drive shaft (1) drives the swash plate (3). The rotation of the inclined swash plate (3) causes the pistons (4) to move
