Air Conditioning Condenser Replacement. Chevrolet Metro 1998

For 1990-2009 cars

### Removal Procedure

Important: When installing a new condenser, add 20-30 mL (0.7-1 fl oz) of refrigerant oil to the refrigeration system.

1. Disable the supplemental inflatable restraint (SIR) system. Refer to Disabling the SIR System in Restraints.
2. Discharge and recover the refrigerant. Refer to Refrigerant Recovery and Recharging .

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

3. Disconnect the negative battery cable.
4. Remove the front bumper. Refer to Front Bumper Fascia Replacement in Bumpers.
5. Disconnect the hood latch cable.
6. Slide the hood latch cable out from the hood latch assembly.
7. Disconnect the electrical connector (1) from the SIR forward discriminating sensor (3).
8. Disconnect the condenser fan electrical connector.
9. Disconnect the 2 horn electrical connectors.
10. Remove 1 bolt and the horn from the vehicle:
11. Disconnect the receiver/dryer outlet-to-evaporator inlet pipe fitting (2).
12. Remove 1 nut (1) and the discharge hose (3) from the condenser.
13. Remove 6 screws and the radiator center brace (1).
14. Remove the 2 condenser mounting bolts (2).
15. Remove the condenser (1) from the vehicle.
16. Cap the refrigerant system openings in order to prevent moisture and dirt from entering the system.
17. Remove the 2 bolts (2) and the 2 screws from the condenser fan (3).
18. Remove the condenser fan from the condenser.

### Installation Procedure

1. Install the condenser fan (3) to the condenser.
2. Secure the condenser fan with the 2 bolts (2) and the 2 screws.
3. Install the condenser onto the radiator support.
4. Secure the condenser with the 2 bolts (2).
5. Install the radiator center brace (1) to the vehicle.
6. Secure the radiator center brace with the 6 screws.
7. Fasten the condenser fan (3) to the center brace with the bolt (2).

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.

8. Connect the discharge hose (3) to the condenser (2). Secure the discharge hose with the 1 nut (1).

Tighten
Tighten the discharge hose to the condenser nut to 9.8 N·m (86.74 lb in).

9. Connect the receiver/dryer outlet-to-evaporator inlet pipe fitting (2).
10. Install the horn to the vehicle. Secure the horn with 1 bolt.
11. Connect the horn electrical connectors.
12. Connect the condenser cooling fan electrical connector.
13. Connect the electrical connector (1) to the SIR forward discriminating sensor (3).
14. Install the hood latch cable.
15. Install the front bumper. Refer to Front Bumper Fascia Replacement in Bumpers.
16. Connect the negative battery cable.
17. Evacuate and recharge the air conditioning (A/C) system. Refer to Refrigerant Recovery and Recharging .
18. Operate the A/C system and inspect for refrigerant leaks. Refer to Leak Testing .
19. Enable the SIR system. Refer to Enabling the SIR System in Restraints.
