PERFORMANCE TEST

Inspection

INFOID:0000000009465943

INSPECTION PROCEDURE

1. Connect recovery/recycling/recharging equipment (for HFC-134a) or manifold gauge.
2. Start the engine, and set to the following condition.

Test condition

3. Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
4. Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-

operating pressure” are within the specified value.

5. When test results are within the specified value, inspection is complete.

If any of test result is out of the specified value, perform diagnosis by gauge pressure. Refer to

REMOVAL

CAUTION:

Before servicing, turn the ignition switch off, disconnect both battery terminals and wait at least three

minutes.
1. Disconnect the battery negative and positive terminals. Refer to

PG-67, "Removal and Installation (Bat-

tery)"

2. Discharge the refrigerant. Refer to

HA-28, "Recycle Refrigerant"

3. Partially drain the engine cooling system. Refer to

CO-11, "Changing Engine Coolant"

4. Remove the front RH wheel and tire using a power tool. Refer to

WT-60, "Adjustment"

5. Remove the engine under cover. Refer to

EXT-15, "Exploded View"

6. Remove the RH fender protector side cover and the RH fender protector. Refer to

EXT-24, "Removal and

Installation"

7. Remove the engine room cover.
8. Remove the air cleaner assembly. Refer to

EM-24, "Removal and Installation"

9. Remove the upper radiator hose.
10. Remove the battery and battery tray. Refer to

PG-68, "Removal and Installation (Battery Tray)"

11. Remove the engine cooling fan and shroud assembly. Refer to

CO-16, "Removal and Installation"

12. Disconnect the high-pressure flexible hose and low-pressure flexible hose from the compressor.

CAUTION:

Cap or wrap the joint of the hose with suitable material such as vinyl tape to avoid the entry of air.

13. Reposition the power steering hose out of the way.
14. Disconnect the harness connector from the compressor.
