VOLUNTARY SERVICE CAMPAIGN
2011 TITAN AND ARMADA A/C RECEIVER / DRYER
This bulletin has been amended to update the OWNER’S LETTER.
Please discard all previous versions of this bulletin.

CAMPAIGN I.D. #: PC117
APPLIED VEHICLES: 2011 Titan (A60)
2011 Armada (TA60)
Check Service Comm to confirm campaign eligibility.

INTRODUCTION
Nissan is conducting a Voluntary Service Campaign on certain model year 2011 Titan and
2011 Armada vehicles to replace the air conditioning system receiver/dryer and, if
necessary, the expansion valve (or expansion valves, as it applies) at no charge for parts
or labor. On some vehicles affected by this campaign, the air conditioning system may
have poor cooling performance because of improperly assembled receiver/dryer
components.

IDENTIFICATION NUMBER
Nissan has assigned identification number PC117 to this campaign. This number must
appear on all communications and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY
Dealers are to correct each vehicle falling within the range of this campaign that enters the
service department. This includes vehicles purchased from private parties or presented by
transient (tourist) owners and vehicles in a dealer’s inventory.

SERVICE PROCEDURE
Remove Receiver/Dryer
1. Discharge (evacuate) the A/C system’s refrigerant.
•

Refer to the operator’s manual of your refrigerant recovery and charging equipment.

2. Remove the radiator as follows:
WARNING: Never remove the radiator cap when the engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from the radiator.
CAUTION: Perform when the engine is cold.
a. Turn the ignition ON, and then set the temperature control lever to the highest HOT
setting or temperature position.
• Wait 10 seconds, and then turn the ignition OFF.

b. Remove the engine undercover or
skid plate.

OR

NOTE: These four (4) skid plate bolts
are T50 TORX bolts.

c. Remove the engine room cover (if
equipped).

i. Disconnect the in-radiator A/T fluid
cooler hoses.
NOTE: Cap or plug the opening(s) to
prevent fluid from spilling.
j.

Disconnect the radiator lower hose
from the radiator.
CAUTION: Do not allow coolant to
contact the drive belt.

k. Remove the lower radiator shroud.
• Release the three (3) lower tabs,
pull the lower radiator shroud
rearward, and then down to remove.

L. Disconnect the radiator upper hose
and the coolant reservoir hose from
the radiator.
CAUTION: Do not allow coolant to
contact the drive belt.
m. Unfasten the coolant reservoir and
bypass cooler hoses from the upper
radiator shroud’s clips.

Hose clips

n. Remove the upper radiator shroud:

r. Tilt the radiator toward the engine, and then remove the external A/T oil cooler bolts.
s. Lift and then move the external A/T oil cooler away from the radiator.
t. Remove the radiator.
CAUTION: Do not damage or scratch the condenser, external A/T oil cooler, or
radiator core when handling.
3. Remove the condenser as follows:
a. Disconnect the high-pressure flexible hose and the high-pressure pipe from the
condenser.
CAUTIONS:
¾ When loosening the bolts, secure the threaded flange with a suitable tool to
avoid twisting the metal piping.
¾ Cap or wrap the joint of the hose and pipe with a suitable material such as
vinyl tape to avoid the entry of air or contamination.
