Let's clear something up. Do you have a clutch fan or electric fans? IF you have a clutch fan (bolts to the water pump) I would suggest removing the electric fans and see if that helps. If you have electric fans why would you have them on both sides of the radiator? You are just blocking the airflow for both fans. If you only have elctric fans get that one up front out of the way so air can pass all the way through the radiator.

If that doesn't work, before you go nuts lets go over a couple things.
1. Are you losing coolant?
2. Is the raditor full? (the radiator not the overflow bottle)
3. Are there air bubbles in the radiator coolant? (check by pulling the radiator cap when the engine is COLD, and runing the car.)
4. Is the thermostat opening? You can check this by feeling your top hose while it is nice and cool, it should be fairly soft. Start your car and let it run until it gets hot, once it hits around 195-200 the T-stat should be open, go back to the top hose and if it is hot and more solid coolant is flowing and the thermostat is opening.

If you have to change the T-stat I would recommend aldo doing upper and lower radiator hoses, goodyear makes some really nice ones or just get some new stockers. Sometimes when they get old they start to collapse and restrict coolant flow. But I wouldn't turn a single bolt until i did all these checks first or you might be throwing a bunch of money away because you have too many fans. Let's get the fan situation clarified cause I amgoing to bet that is your problem. Also you did get the right air dam for your year car right? I think there are 3 different 3rd gen ones
