9. Hold the ambient air temperature sensor (with the bracket attached) on the front bumper bar at the previously marked position and use a center
punch to mark the location for the guide pin hole (callout 2 in the illustration above). Drill a 6.5 mm (1/4 in) hole in the front bumper beam for the
guide pin.
10. Insert the sensor bracket guide pin into the hole. Hold the new ambient air temperature sensor in position and use a center punch to mark the hole
location (at callout 1 above) for the sensor retaining Push Pin, P/N 11589290. Drill a 6.5 mm (1/4 in) hole for the push pin.
11. Apply Synthetic Lubricant with Teflon, P/N 12371287 (in Canada, 10953437), or equivalent, to the holes in the front bumper beam for rust
prevention.
