This bulletin has been amended. The publication date has been updated to include current models.
Please discard previous versions of this bulletin.
APPLIED VEHICLES:
All Infiniti vehicles with A/C system
IF YOU CONFIRM
A refrigerant leak at a refrigerant pipe/hose joint location.
NOTE: Follow the leak detection information in the Electronic Service Manual to determine the source of
refrigerant leaks.
ACTIONS
NOTE: The O-ring seal is the most common cause of a refrigerant leak at an A/C joint.
1. Inspect the metal surfaces of the pipe/hose joint for damage or contamination.
NOTE: Do not replace a refrigerant pipe, hose, or other A/C component if an o-ring seal will solve the leak
incident, if it should occur.
2. If no damage is found to the joint metal surfaces, replace the O-ring seal.
CAUTION:
 When replacing O-ring seals, use lint-free gloves.
 Make sure no foreign material is introduced into the system when the joint is open.
 Apply A/C oil to the O-ring before installation.
 After recharging the system, recheck for leaks.
