Question about GMC Safari
Usually antifreeze and oil mixing causes a dark whiteish milkshake consistancy liquid so if its a dark color i'd guess its REALLY old antifreeze with a lot of corrosion from your engine. Get it flushed and changed a.s.a.p. and hope it didnt mess it up to bad.

you have oil in the cooling system. Check head gasket first then warpage of head then for cracks in head and/or block. This could turn ugly as far as $$ amount. also a job for experienced mechanics.

you may have a blown head gasket ! One major blown head gasket symptom is a consistently high temperature of the car engine. This is a symptom that can be easily checked from the temperature gauge of the car dashboard. So, chronic engine overheating is both a cause and symptom of a blown head gasket.Check the engine coolant level. If it has dropped suddenly, then there is a possibility that the head gasket has blown up.
Check out the engine oil of your car. If you notice a frothy formation on the dipstick, then there is a possibility that coolant and engine oil have gotten mixed due to a blown head gasket. If you notice emission of sweet smelling white smoke along with water droplets from the exhaust pipe, then there are chances that a head gasket has been blown off.
Let the engine rest and cool down for about twenty minutes. Then open the car hood and locate the coolant overflow tank. If you remove the tank cap and it makes a popping sound, that means the cooling system is still pressurized even after engine has shutdown. This is a clear blown head gasket symptom. hope this helps you. have a good day and good-luck !! I want to add that a clogged PCV can contribute to sludging of the engine. If there is any doubt about the condition of the PCV valve, change it. When a part is this cheap, you should not hesitate.
