Check the oil on your dipstick. If the engine is warm, the oil level will be high and look milky or light brownish. If the engine is cold, the oil level will be high and you will be able to see water droplets on the end of the dipstick. If the oil is mixed with the water it will be grey. If not the water will be at the bottom.

Stop driving the car until you have this repaired as the coolant mixed with the oil will destroy the engine.More than likely you have a blown head gasket.
Destroy the engine.
Water is heavier than oil. Oil floats on water.
Not a lot, water and oil don't mix and so the oil will float on top of the water.
oil
When oil and water are mixed together, the oil rises to the top because it is less dense than water. Oil and water do not mix well due to differences in their chemical properties, resulting in the oil forming a separate layer on top of the water.
well simply for any car you can tell by checking the oil or the oil cap. if you see white residue on the cap or on the dipstick you got water in the oil. if you also change the oil you can see water in it. that is simply the only ways you can know. good look with your alero
