10. Check the idler pulley bearing for play and drag,
and replace it with a new one if it's noisy or has
excessive play or drag.
lnstall in the reverse order of removal. Make note of
the following items,
. lf you're installing a new compressor, drain all the
reJrigerant oil from the removed compressor, and
measure its volume. Subtract the volume of
drained oil trom 130 m/ 14 U3 fl'o2,4.6 lmp'oz);
the result is the amount of oil you should drain
lrom the new compressor (through the suction fit-
trngl.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat o{ refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Use refrigerant oil (SP-10) for R-134a KEIHIN spi-
ral type compressors only.
. To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediately after using the oil, replace the cap
on the container. and seal it to avoid moisture
aDsorprlon.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the retrigerant oil con-
tacts the Daint, wash it off immediately.
. Adjust the Ay'C compr'essor b€lt (see psge 22-69)
and the power steering pump belt {see section
17t.
. Charge the system (see page 22-611, and test its
performance (see page 22-56]-.
