   Loosen the intake hose's two clamps with a flat blade screwdriver and pliers and pull it off, then with a drain pan ready, loosen the upper radiator hose clamp with pliers, pull the hose off the radiator inlet, let some fluid drain, and set the hose aside once it stops.

8. Remove the radiator fan

   Disconnect the airbag sensor harness's safety clip and the alternator and airbag sensor harnesses, remove the ground straps' 10mm nuts and pull them off the radiator support, unclip the transmission line and disconnect the fan's wiring harnesses, pull the radiator off its bushings and away from the fan, unclip the fan from the radiator, slide it toward the passenger side, tilt it forward, then pull it up and out.

9. Install the new fan and reposition the radiator

   Angle the new fan into place with a clear path and slide it in, clip it to the radiator and the transmission line, connect its wiring harnesses and the alternator harness, refit the ground straps and their 10mm nuts, reconnect the airbag sensor harnesses and clip them and their safety clip into place, push the radiator onto its bushings, refit the passenger mount and start its 10mm bolt, then push the radiator hose onto the inlet and clamp it.

10. Reinstall the radiator mount, hood latch, and air duct

    Refit the hood latch and the driver-side mount, insert and tighten both mount bolts, keep the hood release cable routed under the air duct as you push it into place and insert its pin, then refit the radiator panel over the latch, start and tighten its three 10mm bolts, and push the panel's two pins and four 10mm bolts and clips back in.

11. Reinstall the headlight, air intake hose, engine cover, and battery, then refill coolant

    Connect the headlight's wiring harness and push it in from the inside before inserting its two bolts, push the air intake hose on and clamp it, twist off the oil cap to push the engine cover back on and twist the cap back on, reconnect the negative battery cable and its cover, then add coolant through a funnel, run the car briefly, and top off as needed.
