I've seen your car before while driving thru Newark one day. The wife pointed it out and I almost wrecked the Cobalt trying to look at it. lolIts there to HELP the cooling system out. If you do not have it then its not going to help the cooling system the same way. But it has and can be done. If you dont want it sell it there are many who do want it. I purchased mine new from the dealer because it is there for the cooling system... *shrug*
