ON-VEHICLE INSPECTION
1. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Remove the glove compartment door.
(b) Remove the lower No. 2 finish panel
(See page BO-84).
(c) Remove the No. 1 cooler cover.
(1) Disconnect the connector clamp.
(2) Remove the 8 screws and No. 1 cooler cover.
(d) Using a gas leak detector, check for leaks of refrigerant.
If there is a leakage of refrigerant, check the tightening torque
at the joints or check the evaporator.
(e) Install the No. 1 cooler cover.
2. INSPECT EXPANSION VALVE
(a) Check amount of gas during refrigeration cycle.
(b) Set on manifold gauge set.
(c) Operate A/C system at ºMAX. COOLº for approx. 5 min-
utes.
(d) Check expansion valve.
Check the low pressure reading drops to 0 kPa (0
kgf/cm
2, 0 psi).
If the low pressure reading is not as specified, replace the ex-
pansion valve with the tubes.
