Models Affected:

911 Turbo 1991-on

Concern:
Under certain circumstances, refrigerant loss from the area of the expansion valve pipe connections can be misdiagnosed as a defective expansion valve.
General Information:
As of production date 10/93, a longer bolt has been used in the installation of the A/C lines to the expansion valve. The new bolt is installed as a
precaution to prevent the expansion valve from distorting which could cause a leak at the pipe connections on the expansion valve.
Repair Information:
Use the new bolt, M6 x 30 mm (see Figure A), when repairs to the expansion valve are necessary. The torque specification for the bolt is 10 N-m. Do not
exceed this torque.
