ON-VEHICLE INSPECTION

  1. INSPECT CONDENSER FINS FOR BLOCKAGE OR DAMAGE If the fins are clogged, wash them with water and dry with compressed air. NOTE: Be careful not to damage the fins. If the fins are bent, straighten them with a screwdriver or pliers.
  2. INSPECT CONDENSER AND FITTINGS FOR LEAKAGE Using a gas leak detector, check for leakage of refrigerant. If there is leakage, check the tightening torque at the joints.

  1. REMOVE LUGGAGE COMPARTMENT TRIM BOX COVER AND TOOL BOX ASSEMBLY
  2. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
  3. DISCONNECT RADIATOR ASSEMBLY Remove the 2 nuts, 2 bolts and 2 spare wheel carrier extensions. Remove the 4 bolts and 2 radiator upper support. Pull up the radiator right side, remove the bush at the bottom side of the radiator from the existing concave, and move it backward.
  4. REMOVE LIQUID TUBE AND DISCHARGE TUBE Remove the 4 screws, RH and LH radiator grilles. Remove 2 bolts and both tubes. NOTE: Cap the open fittings immediately to keep moisture out of the system.
  5. REMOVE CONDENSER Remove the 2 bolts. As shown in the illustration, turn the condenser and pull up the half of it. Then pull up the condenser at a slant. NOTE: Be careful not to damage the radiator and condenser.

  1. Using a 10 mm hexagon wrench, remove the cap from the modulator.
  2. Remove the filter from the modulator.
  3. Using pliers, remove the dryer.
  4. Insert a new dryer into the modulator. NOTE: Do not remove the dryer from a vinyl bag until inserting it into the modulator. Install the dryer with its 2 layered part faced upward to the modulator.
  5. Insert the filter into the modulator. NOTE: Install the filter with its protrusion faced downward to the modulator.
  6. Install the cap to the modulator. Apply compressor oil to the O-rings and screw part of the cap. Compressor oil: ND-OIL 8 or equivalent Using a 10 mm hexagon wrench, install the caps. Torque: 12.3 N.m (125 kgf.cm, 9 ft.lbf)

  1. INSTALL CONDENSER As shown in the illustration, tilt the condenser and insert the half of it. At the time when the half of the condenser is inserted, turn it. Place the condenser in the front of the radiator temporally. NOTE: Be careful not to damage the condenser and radiator. Install the condenser with the 2 bolts. Torque: 8.8 N.m (90 kgf.cm, 78 in.lbf)
  2. INSTALL LIQUID TUBE AND DISCHARGE TUBE Remove the cap. Coat 2 new O-rings with compressor oil. Install both tubes with the 2 bolts. Torque: 9.8 N.m (100 kgf.cm, 87 in.lbf) If condenser was replaced, add compressor oil to the compressor. Add: 40 cc (1.4 fl. oz.) Compressor oil: ND-OIL 8 or equivalent Install the RH and LH radiator grills with the 4 screws.
  3. INSTALL RADIATOR ASSEMBLY Pull up the radiator on right side, install the bush at the bottom side of the radiator to the existing concave, and move it forward. Install the 2 radiator upper supports with the 4 bolts. Install the 2 spare wheel carrier extensions with the 2 nuts and 2 bolts. Torque: 8 N.m (82 kgf.cm, 70 in.lbf)
  4. CHARGE REFRIGERANT TO REFRIGERATION SYSTEM Evacuate air from the refrigeration system. Charge system with refrigerant and inspect for leakage of refrigerant. Specified amount: 500 +/- 30 g (17.64 +/- 1.06 oz.)
  5. INSTALL TOOL BOX ASSEMBLY AND LUGGAGE COMPARTMENT TRIM BOX COVER

  1. INSPECT CONDENSER FAN OPERATION Inspect the fan operation at these condition, as shown in the table. Test conditions: Start engine Blower speed control switch position "HI" Temperature control dial at "COOL" position Set on manifold gauge set A/C switch ON CONDENSER FAN SPECIFICATIONS Condition Fan operation (Fan speed) Engine coolant temperature 88°C (190°F) or below Rotated (Low speed) Engine coolant temperature 98°C (208°F) or above Rotated (High speed) Refrigerant pressure is less than 1,520 kPa (15.5 kgf/cm 2 , 220 psi) Rotated (Low speed) Refrigerant pressure is 1,520 kPa (15.5 kgf/cm 2 , 220 psi) or above Rotated (High speed) If operation is not as specified, proceed to the next inspection.
  2. INSPECT CONDENSER FAN MOTOR OPERATION Disconnect the connector. Connect battery and ammeter. Check that the fan rotates smoothly, and then check the reading on the ammeter. Specified amperage: 9.2 - 11.0 A at 20°C (68°F) If operation is not as specified, replace the fan motor. If operation is as specified, check the pressure switch, cooling fan relays and engine coolant temp, switch.
