O-RINGS:
EVAPORATOR BLOCK FITTING:
All 1985 Cadillacs and the 1984 Cimarron use "captured"-type O-rings at refrigerant hose and tube connections. All other past model Cadillacs use the "standard type" O-ring configuration. The A/C compressor ports to hose assembly continues to use a special O-ring. A new O-ring, specifically for the 3/4" tube of an evaporator/condensor block fitting, has been released. The 1/2" tube of the evaporator/condenser block fitting and the 3/8" tube of the condenser block fitting will continue to use the previous captured O-ring.
The torque specification for the evaporator block fitting bolt (1) has been revised to:
Evaporator Block Fitting Bolt (1), 17 N.m (12 ft. lbs.)
Condenser Block Fitting Bolt (1), 12 N.m (9 ft. lbs.)
Replacement O-rings are available from GMWDD under the following part numbers:
