Air Conditioning Compressor Hose Replacement Compressor Suction Hose

1. Recover the refrigerant using an approved refrigerant recovery system.
2. Remove the air cleaner cover and the air induction hose at the intake manifold.



3. Remove the suction hose from the thermal expansion valve (TXV).



4. Remove the suction hose from the compressor inlet.
5. Remove the suction hose from the vehicle.

1. Remove the protective cover from the suction hose.

Important: Do not lubricate the new slim line seal washer on the compressor side of the suction hose. The slim line seal washer cannot be interchanged with a typical O-ring in the A/C system. Use only suction line slim line seal washers as a replacement.

2. Install the suction hose to the compressor inlet.

Notice: Refer to Fastener Notice in the Preface section.

3. Install and tighten the bolt.

Tighten
Tighten the suction hose-to-compressor to 25 N·m (19 lb ft).




4. Route the hose around the outside of the transaxle dip stick tube, under the edge of the battery tray, and under the negative battery cable.
5. Remove the protective cover.

Notice: Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.

6. Lubricate the O-ring with R-12 Refrigerant mineral oil.
7. Install the suction hose to the TXV.
8. Install and tighten the bolt.

Tighten
Tighten the suction hose-to-thermal expansion valve to 25 N·m (19 lb ft).

Air Conditioning Compressor Hose Replacement Compressor Discharge Hose

1. Recover the refrigerant using an approved refrigerant recovery system.
2. Remove the discharge hose from the compressor outlet.



3. Remove the left front headlamp assembly to gain access to the condenser inlet fitting.
4. Remove the discharge hose from the condenser inlet.

1. Remove the protective cover from the discharge hose.

Notice: Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.

4. Tighten the fitting.

Tighten
Tighten the discharge hose-to-condenser inlet to 23.5 N·m (17 lb ft).

5. Install the left front headlamp assembly.



6. Remove the protective cover from the discharge hose.

Notice: Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.

7. Lubricate the O-ring with R-12 Refrigerant mineral oil.
8. Install the discharge hose to the compressor.
9. Install and tighten the bolt.

Tighten
Tighten the discharge hose-to-compressor to 25 N·m (19 lb ft).

10. Evacuate, charge, and leak test the A/C system.

14. Lift and rotate the TXV end of the liquid line counterclockwise to remove from the vehicle.



15. Remove the pressure sensor from the liquid line.

Notice: Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
