AA EVAPORATOR INSTALLATION
After installing the evaporator, glue the cut dashboard panel
pad with an adhesive agent.
INSPECTION
Air thermo sensor inspection
Measure the resistance between connector terminals 4 and
5 under at least two different temperatures. The resistance
values should generally match those in the graph.
NOTE
The temperature at the check should not exceed the range
in the graph.

B"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
automatic tensioner, the following operation is required for
removing the drive belt:
1. Insert the 12.7sq. spinner handle into the tool hole of
the automatic tensioner and rotate it counterclockwise
until the automatic tensioner reaches to the stopper.
2. Align hole A with hole B for fixing by inserting the
L-shaped hexagon wrench, then remove the drive
belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.
