For 1990-2009 cars

### Removal Procedure

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.

Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL™ coolant. If coolant other than DEX-COOL™ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.

1. Remove the negative battery cable.
2. Recover the A/C system. Refer to Refrigerant Recovery and Recharging in HVAC Systems with A/C - Manual.
3. Drain the cooling system. Recover the coolant. Refer to Cooling System Draining and Filling .
4. Remove the battery and the battery tray.
5. Remove the upper radiator hose.
6. Remove the upper transaxle cooler line.
7. Remove the coolant surge tank hose.
8. Remove the condenser inlet fitting from the discharge hose.
9. Disconnect the cooling fan electrical connection.
10. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General information.
11. Remove the lower closeout panel.
12. Remove the lower radiator hose from the radiator.
13. Remove the lower transaxle cooler line.
14. Remove the evaporator line from the condenser outlet.
15. Remove the lower radiator mounting panel.
16. Remove the CRFM from the vehicle.
17. Remove the condenser from the radiator.
18. Remove the fan shroud from the radiator.

### Installation Procedure

1. Install the fan shroud to the radiator.

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.
