Why is my antifreeze black?
Black coolant can be caused by deterating radiator hoses, crud in the cooling system, and oil getting into the coolant. Not only engine oil from a blown head gasket, or an intake manifold leak, but transmission fluid from a leak in the cooler in the radiator.
Should anti freeze be mixed with oil?
When antifreeze mixes with oil, it robs the oil of its lubricating properties and can destroy an engine. So, antifreeze in oil creates a light brown liquid, that looks an awful lot like chocolate milk.
What causes oil in coolant reservoir?
If the engine overheats the head gasket blows up and causes oil to leak into the coolant system. The engine block typically cracks when the engine lacks proper oiling and cooling due to a heat build-up. When this crack occurs, the oil will start to leak into the coolant.
What happens if you get antifreeze in your oil?
Antifreeze causes a thickening of the oil, increasing the viscosity and not allowing it to flow as readily as before. This can lead to boundary conditions in parts of the engine that require a less viscous fluid to properly lubricate and protect them.
Does antifreeze in oil damage engine?
Motor oil mixing coolant indicates head gasket or engine failure. When antifreeze mixes with motor oil, it reduces the oil viscosity and lubricating power, resulting in loss of engine power and lubrication, leading to engine damage.
What to do if you have black stuff in your coolant tank?
If you’re really worried just drain the system, clean it out and refill. if it was oil, surely it would float on top of the coolant and not stick to the walls of the reservoir? bearing in mind that oil is lighter than water.
Can a cracked engine block cause oil in antifreeze?
If the cracks are internal, on the other hand, you will see oil in antifreeze since the channels where these two fluids pass through has become damaged. Hence, it can be very difficult to detect a cracked engine block until the problem has become very serious. The signs that this has happened are:

What does it mean when oil is mixed with coolant?
If there is oil mixing with coolant, it may indicate that the head gasket is damaged. You can detect this by using your dipstick to check your oil level. If the dipstick has froth, it may be an indicator that there is coolant in your motor oil. The signs that may indicate there is a blown head gasket:
