how do I get rid of air in my coolant lines?
I am still getting a "flushing" noise through my firewall ( passenger side ) when I start the car and sometimes when I just rev the motor at a stop. I am thinking there must be air trapped in the coolant lines that the AST is not removing..
Any other thoughts??
Coolant level appears to be full..

Are you checking the coolant level at the filler neck, NOT the overflow tank? The level should be low at the filler neck if you have air in the system, and it doesn't take much air at all to sound like a waterfall in the pass compartment (that's air moving through your heater core, BTW)

As stated elsewhere, you "burp" it out. Squeeze the rad. hose with the filler cap off. You should see some bubbles come out. Fill it to within 1-2" of the top. Run the car. When it cools off, do it again. It usually takes two to three tries to get it all out.

DO THIS:
1. Open the filler cap
2. Remove the coolant line at the back of the Trottle body
3. Pour in coolant while squeezing the rad. hose to force air bubbles out of the system and out the tb coolant hose.
>>With the Tb coolant line off, all air bubbles should rise to this point since it will then be the highest point in the system.
4. Start the car, warm it up for five minutes with the heater on full (to get bubbles out of the heater core)
The repeat steps 1 through 3
Your're done.

would the air bubbles eventually be gone if you dont do this step? I hear it all the time now when I start my engine and highway driving. Also, sometimes I get the coolant refill light come on me, so I have to refill like a half a cup full. Obviously, I have a small leak somewhere? I'm confused. Oh and I did squeeze the top and bottom radiator hose while filling in to get rid of air bubbles.

If you are getting persistant coolant loss and air in the system, even though you are contantly adding coolant to the filler neck, do the champaign bubble test. You may be in for a nasty surprise...
