For 1990-2009 cars

### Removal Procedure

1. Remove the air cleaner cover and duct assembly. Refer to Air Filter Element Replacement in Engine Controls.
2. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
3. Remove the suction line fitting at the accumulator.
4. Disconnect the suction line at the block fitting bolt.
5. Remove the suction line bracket at the strut tower.
6. Carefully remove the suction line.
7. Remove the O-rings.

### Installation Procedure

1. Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the A/C line and the A/C component.
2. Lightly coat the new O-ring seals with mineral base 525 viscosity refrigerant oil.

Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the new O-ring seals to enter the refrigerant system.

3. For the compression-style fitting at the accumulator, carefully slide the new O-ring seal (1) onto the A/C line until seated.
4. For the line block fitting at the evaporator, carefully slide the new O-ring seal (1) onto the line until seated

Allow a light coating of the refrigerant oil to remain in the A/C line in the area indicated (2) ONLY.

5. Position the suction line into place.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Connect the suction line at the block fitting bolt.

Tighten
Tighten the bolt to 16 N·m (12 lb ft).

7. Install the suction line fitting at the accumulator (2).

Tighten
Tighten the fitting to 47 N·m (35 lb ft).

8. Install the suction line bracket at the strut tower.

Tighten
Tighten the nut to 3.3 N·m (29 lb in).

9. Evacuate and charge the system. Refer to Refrigerant Recovery and Recharging .
10. Leak test the A/C system. Refer to Leak Testing .
11. Install the air cleaner cover and duct assembly. Refer to Air Filter Element Replacement in Engine Controls.
