- Components

1. Suction & Liquid Pipe Assembly

1.If a compressor is available, the air conditioner is operated for a few minutes in the engine idle state and then the engine is stopped.

2.Disconnect the negative (-) battery terminal.

3.Recover the refrigerant with a recovery/charging station.(Refer to Air conditioning System - "Repair procedures")

4.Remove the engine cover.(Refer to Engine Mechanical System - "Engine Cover")

5.Loosen the mounting nut and separate the expansion valve cover (A).

Tightening torque : 7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)

6.Loosen the mounting bolts and separate the expansion valve (A) fron evaporator core.

Tightening torque : 21.6 - 32.4 N.m (2.2 - 3.3 kgf.m, 15.9 - 23.9 lb-ft)

7.Loosen the mounting nuts and separate the suction line (A), discharge line (B).

Tightening torque : 19.6 - 23.5 N.m (2.0 - 2.4 kgf.m, 14.5 - 17.4 lb-ft)

8.Disconnect the APT sensor connector (A).

9.Remove the engine room under cover.(Refer to Engine Mechanical System - "Engine Room Under Cover")

• Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.(Refer to General Information - "Lift and Support Points")

12.Loosen the mounting bolt and remove the Front suction & Liquid pipe assembly (A).

Tightening torque : 7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)

13.Install in the reverse order of removal.

• Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

• Tighten the bolt or nut joint to the specified torque.

• Using a gas leak detector, check for refrigerant leakage.

• Evacuate air in the refrigeration system and charge system with refrigerant.
