>can you blow out the loop with compressed air?
Possibly, though I'm out of state and don't have my tools on hand, I'm lucky enough to have had the money to buy the ramps, no compressor on site though. Could rent it if I get desperate enough, home Depot is ten minutes from here.
I refuse to believe there's no better way, Sebrings were designed to be a mechanic's frequent flyer but not THAT bad. The stopcock for the radiator didn't fully drain it, so I'm currently looking around to see if maybe draining from the engine block will do it.
