The coolant should not be plain water, because it will rust. It should also not be rusty. A thermostat that does not open all the way could cause overheating while driving. Pull the thermostat and check it. Or heck, they're cheap and if it's the original your thermostat is old, just get a new one and see if that was it.
If the coolant is actually oily instead of rusty (looks like coffee) then you may have a blown head gasket.

Hey I'm happy you got it going. Do keep an eye on that coolant color.

It is sort of weird if the very next post is quoting the post above it. It only annoys me when people quote a long string of pictures... I JUST SAW THEM?!@?!?@!?@!!!@?!?@!@
