whats the best way to bleed my cooling system? i know i have air in it because it boils in the overflow tank when i get done driving

 

Try a new rad cap.

 

i did, i got a 15lb one, i think i figured out my problem. my air dam is off from when i had the car apart. could that be the problem of over heating?

 

I have that same problem, but can't seem to find any solutions. I still have my air dam on, and I have a 15 lb cap. My coolant boils out very violently after I turn off my car. A few months ago when I still had my radiator with the plastic tanks and too tight cap, it blew up the radiator. I'd love to know what to do to fix it.
