REMOVAL AND INSTALLATION (Continued)
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 13).
(2) Remove instrument panel. Refer to Group 8E,
Instrument Panel and Systems for Removal and
Installation procedures.
(3) Remove actuator retaining screws. Pull actua-
tor straight off recirculation door shaft. Upon
removal, note the shaft position of the actuator,
because the shaft on this motor is keyed. When
installing new actuator, its shaft must be positioned
in the same location.

INSTALLATION
For installation, reverse the above procedures.

SERVICE PORT VALVE CORES

The 3.2 / 3.5L service port valve cores are located
on the top of the manifold (High Side) and front side
of the manifold (Low Side) (Fig. 29). The 2.7L service
port valve ports are located on the A/C liquid line
(high side) (Fig. 27) and suction line (low side) (Fig.
31).
REMOVAL
(1) Remove the valve caps. Remove refrigerant
from A/C system using a refrigerant recovery
machine.
(2) Using a standard valve core tool, remove the
valve core. Be careful to prevent any dirt/debris
from entering the valve core opening or getting
on the replacement valve core.
CAUTION: A valve that is not fully seated can lead
to damage to the valve during evacuation and
charge. This can result in system refrigerant dis-
charge while uncoupling the charge adapters.
INSTALLATION
For installation, reverse the above procedures.
Evacuate and charge the A/C system.
NOTE: When assembling the new valve core into
the manifold, the core should be oiled with clean
ND8 PAG compressor oil.
