4. Remove the rear coolant recovery reservoir mounting stud.
5. Disconnect the electrical connector from the blower motor.
6. Remove the blower motor access cover retaining screws.

Important: Cut through the cover as straight as possible because the access cover must be replaced. Part of this repair is visible to the customer. In order to prevent damage to the component, do not cut any deeper than is necessary in order to remove the access cover.

7. Cut through the cover on the cut line (1) using a razor blade or a sharp utility knife.



8. Disconnect the cooling tube from the blower motor.
9. Disconnect the electrical connector from the blower motor and fan assembly.
10. Remove the blower motor and fan assembly mounting bolts.
11. Remove the blower motor and fan assembly.

1. Install the blower motor and fan assembly.

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.

2. Install the blower motor and fan assembly mounting bolts.

Tighten
Tighten the bolts to 4.5 N·m (40 lb in).




3. Connect the cooling tube to the blower motor.
