Update: Job went smooth. Used scotch brite inside openings and cleaned up with acetone. Did this because ends of fittings all stayed inside the ports. Took a little while to get two of them out, but not bad. Smeared black rtv in front of o-rings, kind of wish I would have left the bead instead of smearing it, but hopefully it'll be alright. Decided to wait till tomorrow morning to refill with coolant, giving rtv time to cure. Don't know if it makes any difference or not. Will update again tomorrow. Any opinions on what I've done so far is sure welcome.
