how do u know when u have air in the coolant system?? and how u take out the air out?? thanks

My Accords have air bleeder screw on the side of the thermostat housing, but as far as I know you suppose to use it at filling your system with coolant. I do not know if you can use it when you already have filled it up. Most likely yes.

There is a trick that I used to do on my old Subaru:

Park your vehicle on incline nose up.
Open your radiator cap and run your engine.
The air will slowly leave the system.

I hope this helps.
