Rusty coolant will be dark pea green or brown, and look almost slimmey. A Taurus LX... that will be the 3.0L Vulcan. It does have a track record for the cooling systems getting gunked up if not changed as directed (3 years, 36,000-45,000 miles).
If it is actual red/orange coolant and not rusty coolant you still should flush it out and put green back in. Red/orange has a different additive package and can cause increased deposits in the system. Gold, although a long life coolant like red/orange has a more compatible additive package with green, so you can use gold, but make sure the old stuff is fully flushed out if you want the full 5 year interval, but... with the track record of the Vulcan cooling systems, you don't want to leave coolant in longer than 3 years.
Wether you are flushing a dirty system or a mis-filled system out, flush the heater core well!!! Make sure to flush forwards and most importantly backwards. These are the first things to clog when a Vulcan cooling system gets neglected and dirty.
