1. With an assistant, put the cooling fan module into position from below the vehicle, and then hand-tighten the bolts that attach the bottom of the cooling fan module to the ankle catcher.

Note: Make sure that the lower seal from the cooling fan module and lower active shutter grille are sitting flush against each other.

2. Tighten the LH and RH bolts that attach the lower portion of the cooling fan module to the ankle catcher. Torque 10 Nm
3. Install a new o-ring onto the discharge line, and then install the discharge line into the cooling fan module.

4. Install the nut that attaches the discharge line to the cooling fan module. Torque 22 Nm
5. Install a new o-ring onto the suction/liquid line, and then install the suction line into the cooling fan module.
6. Install the nut that attaches the suction/liquid line to the cooling fan module. Torque 22 Nm

7. After installing the suction/liquid line, recharege the refrigerant. See A/C Refrigerant (Recovery and Recharge).

Note: Perform installation of components removed concurrently with refrigerant recharge.

8. Position the coolant drain underneath the RH side of the vehicle.

9. Remove the hose plug, and then install the radiator outlet hose to the cooling fan module. Secure the hose with clip.
10. Position the coolant drain underneath the LH side of the vehicle.

11. Remove the hose plug, and then install the radiator inlet hose to the cooling fan module. Secure the hose with clip.
12. Remove the coolant drain container from underneath the vehicle.

14. Install the front valance. See Valance - Front Fascia (Remove and Replace).
15. Install the front aero shield panel. See Panel - Aero Shield - Front (Remove and Replace).
16. Lower the vehicle fully.

17. Slide the underhood reinforcement bracket onto the top of the cooling fan module.

Note: The cooling fan module tab must be inserted into the isolator so that the trailing tab touches the isolator rubber and the chamfered edge is clearly visible when looking from above.

Note: The trailing edge of the cooling fan module mount must contact the lower tunnel of the isolator.

18. Install the bolts that attach the underhood reinforcement bracket to the body.  Torque 16 Nm

Note: Make sure that there is space between the cooling fan module and the isolator bar to avoid vibration.

19. Loosen the bolts that attach the LH side cooling fan module isolator.

20. Push the LH side of the cooling fan module isolator towards the front of the vehicle until the isolator bottoms out at the top.
21. Tighten the bolts that attach the LH side cooling fan module isolator. Torque 6 Nm
22. Repeat step 19 through step 21 for the RH side cooling fan module isolator.
23. Check the coolant level at the superbottle and add coolant to the full line, if needed.

24. Connect the active grille shutter electrical connector.
25. Connect 12V power. See 12V Power (Disconnect and Connect).
