Scheme 2

MAGNETIC CLUTCH OPERATION

Connect the compressor terminal to battery (+) and the battery (-) terminal to the compressor body. Verify magnetic clutch operation by a clicking noise.

Scheme 3

OIL RETURN OPERATION

To check the oil level or add the oil, idle the engine for 20-30 minutes with the controls set to maximum cooling and blower level, to return the lubricant to compressor.

DESCRIPTION

The combination filter eliminates foreign materials and odor. The combination filter includes an odor filter as well as conventional dust filter to ensure comfortable interior environment.

Scheme 4

1. Remove the glove box.
2. Remove the air filter cover and the air filter. CAUTION: When driving in an air-polluted area or rugged terrain, check and replace the air filter as frequently as possible.

The dual switch is composed of low pressure and high pressure switches. The low pressure switch will be turned off to stop compressor operation if refrigerant pressure is low. The high pressure switch will be turned off to stop compressor operation if refrigerant pressure is too high.

Scheme 10

1. Loosen the tension pulley tightening bolt A, and then remove the drive belt after loosening the tension adjusting bolt B. (Without power steering)
2. Loosen the bolt A, B, C and then remove the drive belt after loosening the tension adjusting bolt D (With power steering).
3. Discharge the refrigerant.
4. Remove the discharge and suction hoses.
5. Remove the compressor.
6. Installation is the reverse of removal. Tightening torque: 24-36 N.m (2.4-3.6 kg-m, 17-26 lb. ft)

Scheme 11

1. Check the condenser fins for clogging and damage. If clogged, clean them with water, and blow them with compressed air. If bent, gently bend them using a screwdriver or a pliers.
2. Check the condenser connections for leakage, and repair or replace it, if required.

Scheme 12

1. Check the condenser fan for proper operation.
2. Check the harness connector.
3. Check the condenser fan motor using battery voltage as shown below.

Scheme 13

1. Check the fusible plug and the fittings for leakage, using a leak detector.
2. Run the engine at fast idle with the air conditioning "ON", and check both the inlet and outlet temperatures. If the difference in temperatures between the inlet and outlet is large, replace the receiver-drier.

Note. Plug the all open fittings immediately to keep moisture out of the system. Do not remove plugs until ready for connection. If the receiver-drier is replaced with a new unit, add 40cc of compressor oil to the compressor. Evacuate, charge and test the refrigeration system.
