2. 2 4868451 Saab 9-5 Introduction The basic A/C kit must be fitted at an authorized SAAB service garage with approved equipment for handling refrigerant. The removal of components in connection with gain- ing access to the system, charging the system with refrigerant, fault diagnosis and checking the perfor- mance of the system is described in Service Manual 8:3 Climate. Read all through the fitting instructions before star- ting work on installing the A/C. Supplementing the basic kit A supplementary kit for the car variant concerned must always be fitted in conjunction with the basic kit (400 107 132). Procedure There are two descriptions of the procedure to be followed when fitting the A/C kit: • Brief fitting instructions, page 13. • Fitting instructions, page 18. The brief instructions are for those who have previ- ous experience of installing A/C units. If no previous experience of fitting A/C units in cars of the type concerned has been acquired, the detai- led fitting instructions should be followed. Important R134a refrigerant is used in all Saab 9-5 models. Note the following: • Since the A/C system is highly sensitive to impurities of all kinds, make sure that no dirt and the like get into it. • The receiver and compressor oil both absorb moisture from the air which cannot later be removed. For this reason, all openings must be plugged until the appropriate components are connected to them. • All new O-rings should be lubricated with synt- hetic vaseline, part no. (45) 30 14 286, on assembly. Supplementary kit : Cars concerned: 400 107 157 Mounting kit R4 engine 400 107 173 Evaporator kit LHD 400 107 165 Evaporator kit RHD
15. 48 68 451 15 Saab 9-5 27 Fitting the kit’s multigroove belt: • Turn the right-hand front wheel outwards and detach the power steering fluid pipe from the subframe. • Drive in a wedge between the oil sump and subframe. • Remove the right-hand engine mounting with yoke and hose holder. • Remove the existing multigroove belt. • Fit the new multigroove belt as illustrated and tension it by releasing the belt tensioner. • Check that the drive belt is correctly positio- ned on all pulleys. • Refit the right-hand engine mounting. Tightening torque 50 Nm • Drive out the wedge and mount the power steering fluid pipe on the subframe. 28 Replace the blanking piece on the heating and ventilation control panel with the A/C pushbutton switch. Check the grooves on the switch with the groo- ves in the panel. 29 Affix the warning label. E980A083 27 30 29 WARNING Affix the label on the right-hand side as illustra- ted.
