Cooling water is brown
 

I noticed that my cooling water is brown. Does this mean that oil is leakin in? Can this happen?
I drained and refilled the anti freeze.

some antifreeze is red. maybee this is what you had. check the oil dipstick. if you had oil in your coolant, you should have coolant in your oil. if you do, the motor will whip it up and it'll look like wayonaise.
