Compressor Oil Port
1. Recover the refrigerant from the A/C system.
2. Remove the oil filler plug and pour the contents
o f o n e b o tt l e o f f l u o r e s c e n t d ye i n t o th e
compressor.
3. Check the O-ring on the oil filler plug and replace
if necessar y. Reinstall the oil plug on the
compressor and torque to 11 to 18 lb ft (15 to 24
Nm).
4. Evacuate and recharge the A/C system with the
proper amount of refrigerant.
5. Install the dye identification sticker on a clearly
visible area on the compressor body close to the
service ports. This will alert service personnel in
the future to the presence of the dye in the
system.
6. Operate the A/C system for about 15 minutes to
circulate the dye throughout the system. Turn off
the system and use the UV lamp and goggles to
locate leaks. The exact location of the leak will be
shown by a bright yellow/green glow of the dye.
NOTE: The operating time needed for the dye to
penetrate a leak and show will depend on the size of
the leak. A very small leak could take hours or days
of system operation to appear.
7. After repairing the system, use fluorescent dye
cleaner to remove any traces of dye from around
the leak location to avoid false diagnosis in the
future.
