1991 Accord Idle control

In the 2.2 liter, 1991 Accord engine the idle air control (IAC) is located
on the intake manifold, a black cilindrical electric motor looking thing.
I have once read on this newsgroup that the idle air control valve can be
cleaned, should be cleaned when the engine idle is not steady.
When wanting to do this, I noticed that the black cilindrical thing cannot
be removed by itself. Also coolant lines are running to the IAC. So now I'm
wondering whether I can remove the whole IAC from the intake manifold,
without having to bleed the coolant?
Any tips, advice?

My '94 Civic has the same setup, IAC on the manifold just behind the
throttle body, and coolant running through it. I have never removed it,
but I have removed the throttle body which also has coolant running
through it. I did not drain coolant, and did not bleed the system
afterwards. I plugged the relevant (small diameter) hoses with a piece
of paper towel as I removed them and made sure the opening was sitting
as high up in the engine bay as possible. I lost maybe a tablespoon of
coolant.

My guess is that I can remove the three bolts mounting the IAC assembly to
the manifold. But what next, what is there to clean? How do I clean this?
Use somekind of solvant?

Pull the 3 bolts and leave the hoses connected. Just pull the unit away from
the intake (won't give you much room to work with it). I used a spray carb
cleaner, like Berryman's.
