If the compressor is marginally operable, run the engine at
idle speed, and let the air conditioning work for a few minutes, then
shut the engine off.
2.
Disconnect the negative cable from the battery.
3.
Recover the refrigerant with a recovery/charging station.
4.
4. Loosen the drive belt.
(Refer to EM group - "Drive belt")
5.
Loosen the mount bolts and then remove the under cover (A).
6.
Remove the bolts, then disconnect the suction line (A) and
discharge line (B) from the compressor. Plug or cap the lines
immediately after disconnecting them to avoid moisture and dust
contamination.
7.
Disconnect the compressor clutch connector, and then remove mounting bolts and the compressor(B).
Installation
1.
Make sure of the length of compressor mounting bolts, and then tighten it A>B>C>D order.
Tightening torque :
20.0~32.9N.m (2.04~3.36kgf.m, 14.7~24.3lbf.ft)
2.
Install in the reverse order of removal, and note these items.
–
If you''re installing a new compressor, drain all the
refrigerant oil from the removed compressor, and measure its volume,
Subtract the volume of drained oil from 120cc(4.20 oz.) the result is
the amount of oil you should drain from the new compressor (through the
suction fitting).
–
Replace the O-rings with new ones at each fitting, and apply a
thin coat of refrigerant oil before installing them. Be sure to use the
right O-rings for R-134a to avoid leakage.
–
To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
–
Immediately after using the oil, replace the cap on the container and seal it to avoid moisture absorption.
–
Do not spill the refrigerant oil on the vehicle; it may
damage the paint; if the refrigerant oil contacts the paint, wash it off
immediately.
–
Adjust the drive belt (Refer to HA-14)
–
Charge the system and test its performance.
Inspection
Field Coil
[Operation]
1.
Remove the compressor.
2.
Check operation of the magnetic clutch. Connect the
compressor connector terminal "3" to the battery (+) terminal and the
ground battery (-) terminal to the compressor body. Check the magnetic
clutch operating noise to determine the condition.

ECV (-)
[Resistance]
1.
Disconnect the ECV connector from the compressor.
2.
Measure resistance between compressor body and terminal "3" of the ECV connector.
Resistance Specification : 2.8 ~ 3.2?
ECV resistance may be slightly higher or lower than the specification, depending on the temperature of the ECV.
•
Be aware of ECV Bent Pin.
•
Plug / Unplug the connector carefully.
Compressor Field Coil check procedure (Only Clutch Type)
Electronic Control Valve Compressor Inspection (Tester)
1.
Disconnect the ECV connector from the compressor.
2.
Measure resistance between terminal "+" and "-" of the ECV connector.
