getting Rid Of Plastic Shield
Leave the air dam on, no questions asked, because it's necessary to get air to flow to the radiator. Take off some of the other lining if you like (use zip ties afterward on the panels, much easier to work with), but be warned -- better check the route of your air intake, so as to not get water up in there!
As for the tool, a flathead screwdriver and diagonal pliers (snips, dikes, etc) have always worked for me. There ARE specific tools avail from snap on, etc., but i'm not at that level yet.
whether it really drops your radiator temps any
(which would be hard to know without putting a
thermocouple to it I expect). I don't believe GM
would have invested the $5 in that piece if it
didn't do something. What I think goes on is, the
air dam ("chin spoiler") forces air up, and the
ducting leaves it nowhere else to go but into the
radiator. If you remove it, you may let it just go
over the top, into the engine compartment or
elsewhere, and defeat your intention of improving
radiator airflow in the end.
