Refrigerant Connection: Installation

WARNING: This page is about a different car, the 2013 Infiniti FX50. However, it is still accessible from the selected car via links, so may be relevant.

Clean piping connection points, and insert male-side piping into female-side piping.
Push inserted male-side piping harder so that female-side piping flare stretches garter spring.

Garter spring seats on flare if inside diameter of garter spring becomes larger than outside diameter of female-side piping flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor piping connection point.
NOTE: When garter spring seats on flare, and fits in between male-side piping cage and female-side piping flare, it clicks.
CAUTION:
- Female-side piping connection point is thin and easy to deform. Slowly insert the male-side piping straight in axial direction.
- Insert piping securely until a click is heard.
- After piping connection is completed, pull male-side piping by hand to make sure that connection does not come loose.
