Blowing out the water jacket.

[In The Ten Ring]

I am getting very close to restarting the engine.

My dad suggested I "blow out the water jacket" with compressed air.

She has not run since 2006 so this might be a good idea.

But first I should ask, what would you guys do in order to clean out the water jacket? How would you do it?

Is there a commercially available set up for this?

Where might I find it?

If not, how might I do it with compressed air?

Thanks!
