APPLICABILITY ALL 1989 MODELS EQUIPPED WITH FACTORY OR

ACCESSORY AIR CONDITIONING SYSTEMS

SUBJECT: SIZE MODIFICATION OF THE A/C HI PRESSURE-DISCHARGE SERVICE VALVE

THIS BULLETIN IS FOR INFORMATION ONLY

Starting with the 1989 MY, all Subaru factory installed A/C systems and all accessory A/C systems will have the pressure-discharge service valve decreased in size from a 7/16" (20 universal national fine thread) to a 3/8" (24 universal national fine thread). The purpose of the decreased size is to distinguish the low pressure suction servicing valve from the high pressure discharge service valve during testing or charging.

NOTE: Wynn's climate systems air conditioner part number SOA329A107 is currently using the 3/8" (24 universal national fine) pressure discharge valve size.

Because most charging and testing equipment use a 7/16" (20 universal national fine) size fittings, an adaptor will be necessary.
Example: Snap-on part number ACT 107A Hi-port side adaptor.
