A/C - Receiver Drier Fuse Plug Elimination

Applicable Model/s (listed below)
Subject ELIMINATION OF FUSE PLUG FROM RECEIVER/DRIER TANK

Bulletin No. 007/90

DESCRIPTION

In order to comply with the SAE standard (J639), a pressure relief valve has been incorporated on the air conditioner compressor for the following models: '88-'91 626/MX-6, '86-'91 RX-7 and '86-'91 B-Series. The pressure relief valve is designed to release refrigerant in order to protect the A/C system if the high side pressure reaches 450 psi.

As a result of this pressure relief valve, the fuse plug previously used as a safety device is no longer needed and will be eliminated from the receiver/drier tank. However, the receiver/drier tank with the fuse plug will still be available as a service part for the models listed below because the A/C compressor used in early production of A/C kits for these models did not have the relief valve.

When replacing the receiver/drier tank during A/C service, check whether the A/C compressor has a pressure relief valve or not.

CAUTION:
The receiver/drier tank without the fuse plug should not be installed on vehicles in which the A/C compressor does not have a pressure relief valve.
