Air dam and belly pan

[wildfire8]

A few weeks ago I made and air dam with garden edging. I had bumper block and belly pan on when I did it. I found that it really helped with aero. The engine didn't have to push so hard. But kept having heat problems. I was thinking that the air dam was not letting air get under the car to let the hot air that was in the engine bay get pulled out threw the exit duct on the belly pan.

Should I have belly pan and air dam or just air dam?
Any other info about air dam's would help thanks?

I think your better off with the belly pan with out the air dam. What I would like to do on my caprice is pick up a 2nd hood and put some kind of vent like an evo or maybe cut holes in the inner fenders

You do need to make sure there is some airflow through the rad. In the winter you might get away with a full block. You need to leave an opening in your grille and in the belly pan. You can experiment with the grille by changing the block till it does not overheat. The best way would be to have a good size opening in your belly and change the rad block till optimal. Or if you are inventive, an adjustable grille block.

Is your rad fan working?
