4. Procedure
Subtask 30-72-11-420-051-A ** ON A/C NOT FOR ALL
A. Installation of the Thermostat
   (1) Clean the component interface and/or the adjacent area.
   (2) Do a visual inspection of the component interfaces and the adjacent area.
   (3) Make sure that the surface of the locating stud (6) is clean before you apply the adhesive.
   (4) Apply Threadlocking Adhesive-- Low strength Low viscosity - (Material No.05BAB1) on the locating stud (6).
   (5) Put the thermostat housing (5) onto the locating stud (6).
   (6) Put the washer (8) and the threaded sleeve (9) in position.
   (7) TORQUE the threaded sleeve (9) to between 0.06 and 0.04 m.daN (5.31 and 3.54 lbf.in ) T.
NOTE: A threaded overlap is not necessary.
   (8) Install the thermostat housing cover (3) with the screws (7), the washers (2) and the nuts (1).
   (9) Remove the CAP-BLANKING from each electrical connector and receptacle.
CAUTION: MAKE SURE THAT THE ELECTRICAL CONNECTORS ARE CLEAN BEFORE YOU DISCONNECT OR CONNECT THEM. CONTAMINATION ON THE ELECTRICAL CONNECTORS CAN CAUSE DAMAGE TO EQUIPMENT.
