Inspect For Leakage Of Refrigerant

(a) Remove the glove compartment door. Remove the lower No. 2 finish panel (See page BO-84 ). Remove the No. 1 cooler cover.

(1) Disconnect the connector clamp.

(2) Remove the 8 screws and No. 1 cooler cover. 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. INSPECT EXPANSION VALVE Check amount of gas during refrigeration cycle. Set on manifold gauge set.

Operate A/C system at "MAX. COOL" for approx. 5 minutes.

Check expansion valve. Check the low pressure reading drops to 0 kPa (0 kgf/cm2, 0 psi).

If the low pressure reading is not as specified, replace the expansion valve with the tubes.


Reassembly is in the reverse of disassembly (See page AC-76).
