Removal Procedure

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

    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.

  1. Remove the battery. Refer to Battery Replacement in Engine Electrical.
  2. Remove the battery tray. Refer to Battery Tray Replacement in Engine Electrical.
  3. Recover the A/C system. Refer to Refrigerant Recovery and Recharging in HVAC Systems with A/C - Manual.

  16. Remove the lower radiator mounting panel.
  17. Remove the radiator, fan and condenser as an assembly from the vehicle.
  18. Remove the condenser from the radiator.
  19. Remove the fan shroud from the radiator.

Installation Procedure

  1. Install the fan shroud to the radiator.
  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.
