The plastic front air dam on a Chevrolet Silverado can take a lot of abuse. It's the lowest thing on the body, and the first thing to hit when entering a steep driveway or coming towards a curb. If you damage one, they're not very expensive to replace, but they can be a bit frustrating to remove. In this case, the project vehicle is a 2002 Chevrolet Silverado, but the process is similar for other vehicles as well.
Slide underneath the front bumper and locate the pins that secure the front air dam to the bumper. Note how the clip goes together. There is a flat surface that goes against the air dam directly, and then there's a pin that goes inside of the first one.
Start with one of the clips on the very end of the air dam by the tires. Place the interior clip tool between the pin and the flat surface of the clip, and twist the pin out of the clip. This is going to do the initial release of the clips.
Place the interior clip tool between the air dam and the bumper, centering the tool around the clip. Twist and pull the interior clip tool to release the clip from the bumper.
Repeat steps 2-3 for each clip on the bumper, working your way from one side of the bumper to the other until the entire air dam is unclipped from the bumper.
