If it was contaminated with coolant, you would see white streaks in the fluid or, in a bad case, a pinkish-white custard-like substance. The fluid shouldn't be brown, but I've seen old, Nissan Type "J" fluid take on a brownish tint. At the very least, it should be serviced. It's probably a good idea to get it looked at, first, though, by a professional.
