Well, took her out for a shakedown trip last night and all I can say is keep a close eye on the temp gauge after doing this! I had filled the reservoir after reconnecting all the lines, and even let her warm up a bit before taking her out. But after driving for about 5 min., the low coolant light went on and the temp shot up to "A." Pulled over and put about a quart of coolant/water into the tank. Drove for another 5 min. and the same thing happened. Added another quart or so.
Long story short, I guess draining the coolant out of the hoses introduced a TON of air into the system. I knew I'd have to fill it up a bit (which is why I was carrying a bottle of coolant with me), but I was surprised to see it needed that much.
Everything's fine now - no decrease in coolant level after the 2nd. refill.
