ON-VEHICLE INSPECTION
1. Check the condenser fins for blockage or damage.
If the fins are clogged, clean them with compressed air.
If the fins are bent, straighten them with a screwdriver or pair of pliers.
2. Check the condenser fittings for leakage.
Repair or replace, if necessary.
REMOVAL OF CONDENSER
1. Discharge the air conditioning system. (Refer to page 16—9.)
2. Remove the front grille and the air seal cover.
3. Disconnect the discharge flexible hose from the condenser inlet fitting.
4. Disconnect the liquid line pipe from the condenser outlet fitting.
Note:
Plug the open fittings immediately to keep moisture out of the system.
6. Remove the condenser.

76G16X-637
INSTALLATION OF CONDENSER
1. Install the condenser by using the two bolts and two nuts.
2. Connect the liquid line pipe and the discharge flexible hose to the condenser.
Tightening torque:
Liquid line pipe: 15—25 Nm (1.5—2.5 m-kg, 11—18 ft-lb)
Discharge flexible hose: 15—22 N-m (1.5—2.2 m-kg, 11—16 ft-lb)
3. Install the front grille and the air seal cover.
4. If the condenser is replaced with a new one, supply compressor oil.
Compressor oil: 30 cc (1.83 cu in)
5. Evacuate, charge, and test the air conditioning system.
