Many Chevy Colorado owners are opting to remove their lower valance, AKA air dam, for a sleeker look. According to these before and after pics, the removed air dam does give the truck a meaner appearance.
Stan Ludlow, GM Program Manager, said that while the air dam is there for fuel economy, it can be taken off for off-roading. The air dam drastically reduces angle of approach, but you might also lose some fuel economy with removal.
Removing the Air Dam
1. Open the hood and remove the 6 hex screws that hold down the upper portion of the grille assembly. There are three on the driver’s side, and three on the passenger’s side.
2. Remove the 8 hex screws that hold in the felt wheel liner on each side.
3. Once you’ve peeled the liner back, a plate will appear at the bottom of the bumper.
Take it off by removing the hex screws and 10mm bolt. It’s one big plastic piece and looks like this when removed:
4. Remove the wire to the fog lamp.
5. Find the three hex screws that are located near the edge of the headlight and remove them, as shown here:
6. Once the three screws have been removed, the outer portion of the face can easily be popped out of the fender. However, before it comes completely off, you must remove the 2 recessed 10 mm bolts in the grille as shown here.
7. Last, there are 2 more 10 mm bolts—one of the driver’s side and one on the passenger’s side—that need to be removed. They are located where the plastic piece you removed in step 3 was. The specific bolt is shown here:
8. Work the facia and lay it face down, preferably on a rubber mat or a blanket to prevent scratches.
9. Remove all the hex screws that are holding the air dam on.
10. Reassemble the front facia of the truck.
11. Enjoy your slick new ride!
