Tightening torque: Nm (kg-m, ft-lb)

T1: 15 - 25 (1.5 - 2.5,11 - 18)
T2: 10 - 20 (1.0 - 2.0, 7 - 14)
T3: 7 - 13 (0.7 - 1.3,5.1 - 9.4)

6. Check to see if the evaporator fins are clogged. If they are, clean them with compressed air. Water must never be used to clean the evaporator.
7. Check parts that have been removed for cracks or scratches, and repair or replace them with new ones, if necessary.
8. Reassemble the evaporator in the reverse order of disassembly. Observe the following points during the reassembly process:

a. Confirm that the 0-ring is inserted in the specified position.
