Removal
NOTE: Make sure the suction and discharge ports are plugged with caps.
1. Remove the relief valve cover, relief valve, and 0-ring.
NOTE: Be sure to use the right 0-rings for HFC-134a (R-134a) to avoid leakage.
CAUTION: Be careful not to spill compressor oil, and make sure there is no foreign matter in the system.
Installation
1. Clean off the relief valve mating surface.
2. Replace the relief valve 0-ring with a new one and apply a thin coat of refrigerant oil (SP-1O: P/N 38899-P13-AO1) before installing it.
NOTE:
^ To avoid contamination, do not return the oil to the container once dispensed and never mix it with other refrigerant oils.
^ Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
^ Do not spill the refrigerant oil on the car; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
3. Tighten the relief valve.
4. Put the cover on the relief valve so that the arrow points downwards as shown above.
