Odds are you have blown a head gasket and the antifreeze and oil flow share the same gasket. As the gasket wears, the antifreeze mixes into the oil and vice versa! I suggest replacing your current antifreeze and do a full flush. Test it for a few days and test if you have oil again. A tell tell sign of a blown head gasket is black smoke (burning oil) or white smoke (burning antifreeze ) coming out the exhaust.

sounds like you have a cracked head or cracked block.however, i would check to make sure it is not transmission oil and thereby ruling out a radiator problem


Water pump leak oil in radiator?

You did not say what you are working on, YEAR AND ENGINE SIZE. But in most cases or designs the water pump can not leak oil into the coolant. The water pump has nothing to do with the engine oil. Does the engine have a engine oil cooler on it ? That would be 2 oil lines just above the oil filter that runs down the side of the engine oil pan a go to the radiator. There are tubes inside of the radiator that oil flows through and they are none to leak oil into the engine coolant that's inside of the RADIATOR. If they are leaking then REPLACE RADIATOR. BUT like I said I don't know what you are working on. Would like to help you with your problem, But need more INFO. NEUTZ.

Why is antifreeze blowing out from the radiator cap of a Nissan Titan?

If it's just blowing out when you start it you probably have a cracked head or blown head gasket. If there is oil in the radiator there is a change you have oil coming in from the transmission cooler. But there would have to be a lot of oil to make antifreeze come out the radiator cam. Since you did not mention oil I would suspect the head gasket. If you got it hot I would lean toward a cracked head.

How do you know if a radiator has a auxiliary transmission oil cooler on it?

If there are lines coming from the transmission to the radiator, it has a cooler in the radiator. If there are lines from the transmission to an external heat exchanger, that would be an auxiliary cooler.


Why would there be oil in the radiator and no water in it?

Bad Head Gasket. See a mechanic ASAP..


What would cause oil to be in your radiator on your Chevy surburban?

Really need to know the year and engine size. But you can check this, Does your engine have 2 lines just above the oil filter that run up the side of the engine and goes into the radiator on the drivers side ? If so then that is the engine oil cooler lines and the tubes in the radiator were the oil flows through to cool the oil are probley leaking into the radiator coolant. IT happens often. WILL NEED TO REPLACE RADIATOR. And flush out the cooling system real GOOD. Did your engine freeze from lack of antifreeze ? If the radiator fluid is cheery red looking then the transmission cooler that is built into the radiator is leaking. REPLACE RADIATOR. GOOD LUCK.


Why would there be oil in your antifreeze you have a 1995 Chevy big block truck?

The most common reason would be a ruptured oil cooler in the radiator. Check to see if you have oil lines going to the radiator, if you do, you need a radiator. Also, don't forget to change the anti-freeze because it will be contaminated. Don't forget to check your transmission for contamination also, as transmission fluid also runs on the outer region of your radiator to cool the transmission fluid.


You have just noticed oil in your radiator of your E46 318i any clue of how oil would migrate there?

Oil in the radiator on any vehicle is a sign that there is a blown head gasket. This includes the E46 318i motor. Oil in the radiator is also a sign that the block is cracked. Either way, it is a major issue that needs to be addressed before the engine quits completely.

What causes oil and water mix in the radiator?

Are you sure that isn't antifreeze and if so that would indicate the radiator is defective. There is a transmission oil cooler in the radiator.

How is there transmission fluid in your radiator?

The automatic transmission oil cooler is built into the radiator. If the oil cooler developes a leak the oil mixes with the engine coolant.


What would cause there to be oil in the radiator but not water in the oil?

Pressurized oil lines go from the block through to the head. If the head gasket is leaking at that point and allowing a small amount of pressurized oil to seep between the line and the coolant jacket you could get oil in the radiator. Another possibility is that perhaps someone used water pump lubricant which is nothing more than an emulsified oil (oil blended with water). Over time the oil can separate from the coolant and that might be all you're seeing, especially if it isn't much oil. If it's RED oil it could be comming from the transmission cooler line. That runs through one of the radiator tanks and if the transmission line is leaking you could certainly get oil in the radiator... but it' would be red.


If there is oil in the rad what might that mean?

If it is a pink color then the Transmission cooler is bad in the radiator, If it is oil for sure then the engine oil cooler that's in the radiator may be leaking oil into the radiator. It would really help to know the year ,engine size and what you are working on. The above info may not pertain to your vehicle. Need to ask your question again with all information. THANK YOU NEUTZ.

What does oil in a radiator of a 89 Honda Accord mean?

If its engine oil I would say head gasket or cracked head. Also check under the oil fill cap for a milky color. You can also run the car a few minutes remove the radiator cap see if it smells like gas . Most shops use what they call a sniffer but, Ive found that I can smell the exhaust in the radiator. More than likely head gasket answer is the car automatic? if it is , have your radiator checked to see if transmission fluid is leaking into radiator from oil tank at bottom of radiator if it is engine oil and not transmission oli, you have a cracked head allowing oil to seep into the water chamber a bad head gasket allows water into engine oil, not oil into water


What happens when putting oil in the radiator system?

(Oil floats) mostly mixes with the water forming emulsion which clogs the radiator.
