If you observe oil in the radiator reservoir tank its an abnormal case and you should check it out. In more modern automobiles the radiator contains a lot of plastic.
How To Fix Coolant In Oil In Under 2 Hours
Oil in radiator overflow. They should not be mixed. Have the service department do a full oil and filter change after they have put the new radiator in. I do not remeber the cost of the part exactly. This part is often much easier to replace and cheaper than a head gasket. Show full signature. It means there is something wrong.
Draining the radiator just allows the oil in the overflow to drain down into it. This is often causing the coolant to pour into the oil pan instead of oil in the coolant system. Coolant and oil both are very much important for the engine. While running oil pressure should exceed radiator pressure but when cooling down i am not so sure. Once it cools down and contracts the coolant is returned to the engine. Excess coolant is captured in the overflow tank so it wont leak.
Sometimes a gasket or a crack could occur inside the oil cooler and it will cause the oil and coolant to mix up. On a lot of modern cars there is an oil cooler fitted on your car which is cooled by the coolant. In older automobiles the radiator was made of copper and aluminum. If oil got into the coolant because of an oil cooler leak there is a possibility that coolant got into the oil as well. Since it can become a more serious issue in the future we highly recommend you to have proper leak tests for the engine performed by a professional mechanic so that the car could avoid severe damages and extend its life. Its also a very common problem so i recommend checking the oil cooler if you have one fitted to your vehicle.
I had drained the system prior to removing the heat exchanger and was shocked at how much oilcoolant was still left in the engine. Since oil is lighter than water most of the oil in your cooling system will float to the top of your radiator or coolant overflow tank. Radiator if the cap thermostat and water pump are all fine the reservoir is overflowing most likely because of a radiator problem. It will result in them becoming diluted which will prevent them from performing their function in the engine. Oil in coolant reservoir could be a minor leakage result or serious problem which could be checked in time if you take immediate action. If you see an oil slick floating on your coolant its important to clean out your cooling system to make sure your engine doesnt overheat.
If its not the cooler then it could be passages in the head which are allowing oil to tget in the coolant or head gasket concerns or damage in the block. Maybe thats why it is taking so long to clear it out. Im beginning to think that if i just keep flushing it will eventually clear. These two fluids should never mix.
