Inspection

I
Check the front and rear pulser for chipped or dam-
aged teeth.
Measure the air gap between tho wheel sensor and
pulser sllthe way around while rotating the pulser.
Standard: 0.4 - 1.0 mm (0.02 - 0.04 in)
NOTE: lf the gap exceeds 1.0 mm (0.04 in), the
probability is a distorted suspension arm which
should be reDlaced.

Remove the self-tapping screws and clamps from
the housing.
3. Carefully separate the housings and remove the
evaporator.
4. lf necessary. remove the expansion valve.
NOTE: When loosening the expansion valve nuts,
use a second wrench to hold the expansion valve or
evaporator pipe. Otherwise, they can be damaged.
Assemble in the reverse order of disassembly.
Make note ot these items:
Replace the O-rings with new ones at each fit-
ting, and apply a thin cost of retrigerant oil (ND-
OIL 8: P/N 38897 - PR7 - A01AH or 38899 - PR7 -
A01) before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage.
Install the expansion valve capillary tube with
the capillary tube in contact with the suction line
directly, and wrap it with tape.
Reinstall the Ay'C thermostat sensor to its original
location.
