Bulletin No. T-88-160
File in Group 1
Number 54
Corp. Ref. No. 811210
Date July '88
SUBJECT: COMPRESSOR HOSE ASSEMBLY REFRIGERANT LEAK

MODELS AFFECTED: 1988 DE VILLES AND FLEETWOODS


Some 1988 DeVilles and Fleetwoods may experience a service A/C light due to a refrigerant leak from the compressor hose assembly. BCM diagnostic codes F46, F47, and F48 may also accompany the refrigerant leak. This condition may be caused by a mispositioned or bent center compressor suction hose bracket restricting the movement of the hose.

FIGURE 1 - COMPRESSOR HOSE ASSEMBLY BRACKET:




To repair this condition after replacing the compressor hose assembly, if necessary loosen the center retaining bracket nut and reposition the bracket, then bend the bracket outward to the shape shown in Figure 1, maintaining constant clearance to valve cover.
For warranty purposes use Labor Operation T6321 at .2 hour to reposition and/or shape the center compressor suction hose bracket.
