oil capacity CHRYSLER VOYAGER 2005 User Guide

rest of the system must be drained from the replace-
ment A/C compressor. The oil capacity of the system,
minus the amount of oil still in the remaining com-
ponents (refer to the oil capacity chart below) can be
measured and poured into the suction port of the A/C
compressor. When a line or component has ruptured
and oil has escaped, the receiver/drier must be
replaced along with the ruptured component.
Example: On this A/C system the front A/C evapo-
rator retains 50 ml. (1.7 oz.). The A/C condenser
retains 50 ml. (1.7 oz.) of oil, and front A/C system oil
capacity is 180 ml. (6.1 oz.).
180 ml. ± 100 ml. = 80 ml. (2.7 oz.).

VERIFY REFRIGERANT LUBRICANT LEVEL
(1) Recover the refrigerant from the system.
(2) Disconnect the refrigerant lines from the A/C
compressor. Cap open lines to prevent moisture from
entering the system.
(3) Remove A/C compressor from the vehicle.
(4) From the suction and discharge ports on the
A/C compressor, drain the lubricant from the com-
pressor.
(5) Add the system capacity minus the capacity of
the components that have not been replaced. Refer to
the A/C Component Refrigerant Oil Capacities chart.
Add lubricant through the suction and discharge
ports on the A/C compressor.
(6) Install the A/C compressor and connect the
refrigerant lines. Then evacuate and charge refriger-
ant system.
(7) Most reclaim/recycling equipment will measure
the lubricant being removed. This amount of lubri-
cant should be added back to the system. If a new
A/C compressor is being installed, drain the lubricant
from the used compressor, measure the amount
drained and discard the used lubricant. Drain the
lubricant from the new A/C compressor into a cleancontainer. Return the amount of lubricant measured
from the used compressor, plus the amount reclaimed
from the system back into the new A/C compressor.
Refer to the reclaim/recycling equipment manufactur-
ers instructions.
SERVICE PORT VALVE CORE
DESCRIPTION
A/C SERVICE PORT VALVE CORES
The low side valve is located on the suction line
near the A/C compressor. The low side A/C service
port valve core is a serviceable item. The high side
A/C service port valve core is located on the liquid
line fitting attached to the top of the receiver/drier.
The high side A/C service port valve core is not a sep-
arate serviceable item. If the high side service port
valve core is faulty or damaged, the front section of
the liquid line will require replacement.
REMOVAL
WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFORE
PERFORMING THE FOLLOWING OPERATION (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMBING -
FRONT - WARNING - A/C PLUMBING) and (Refer to
24 - HEATING & AIR CONDITIONING/PLUMBING -
FRONT - CAUTION - A/C PLUMBING).
(1) Recover the refrigerant from the refrigerant
system (Refer to 24 - HEATING & AIR CONDITION-
ING/PLUMBING - FRONT/REFRIGERANT - STAN-
DARD PROCEDURE - REFRIGERANT
RECOVERY).
(2) Using a standard Schrader-type valve core tool,
remove the valve core from the low side A/C service
port located on the suction line.
(3) Install a plug in or tape over the opened low
side A/C service port.
INSTALLATION
(1) Lubricate the low side A/C service port valve
core with clean refrigerant oil prior to installation.
Use only refrigerant oil of the type recommended for
the compressor in the vehicle.
(2) Remove the tape or plug from the A/C service
port located on the suction line near the A/C com-
pressor.
(3) Using a standard Schrader-type valve core tool,
install and tighten the replacement valve core into
the low side A/C service port.
