I've had this before and it turned out to be the oil cooler had a very small hole in it, and needed to be replaced. Roughly $1200 about two years ago. In my case, on top of the fluid in the reservoir having a chocolate color to it, it had started to leak out of the cap of the radiator reservoir. This is due to the added pressure of the oil system. If you don't see this at all, then it could be a blown head gasket as well as a few other things. I have a 2000 Saab, and have been told this is a common problem though, so the oil cooler is my best guess. Kind of a complicated repair, it is internal to the engine (on my model)

I was having the same problem with my car. When you take the thermostat out it will automatically read cool. But I later found out that I had a leak in my radiator and had to replace it. Turned out that my heads are warped and was leaking oil into my water and into the radiator itself. Once i replaced the radiator its been fine.

Low coolant? Cooling fan not working? Radiator plugged or restricted? Water pump not circulating coolant? System air bound? Defective radiator cap?

Over-obvious answer? Your radiator, or one of your radiator hoses, leaks - badly.
