I have a slight amount of oil in my radiator, I had this years ago and my dealer fixed it and said it was something small. Anyone know what it maybe or had the same experience. Thanks


This is a concern that requires immediate attention. Oil in the coolant or coolant in the oil is an indication that the integrity of the engine has been compromised and a passage has developed between the oil and coolant.

Installed in some radiators is a transmission coil cooler that is connected usually at the bottom of the radiator by two metal tubes. A failure internally of the radiator could breach the separation.

Head gaskets that have coolant pass through openings can also be a failure allowing the liquids to mix.

Look for coolant in the engine oil.
Check for oil level overfull

Look for steam from exhaust

Hope this helps.

Have repair done ASAP at qualified shop

97 mercury mountaineering has oil in the radiator and coulant. Help please!


OK, lets figure out what's happening here. You are seeing "oil" in the radiator and coolant. Chances are it is not engine oil. The inly way engine oil can get into a radiator would be if a head gasket was blown. Even then, oil at those locations is not under as much pressure as the coolant is, so when a head gasket blows, what usually happens id that the coolant ends up in the motor oil and oil pan. Verify this by looking at the dipstick to see if it is extremely full. The oil could look like choclate milk. Also, open the oil filler cap and look for signs of chocolate brown goop. I'm betting you won't find that. This is good, but also bad. What you probably have in you coolant is transmission fluid. The transmission oil is circulated through a cooler located inside the radiator. If this cracks or breaks the transmission oil can leak into the coolant. However, at different times the transmission oil and the coolant are at odd with one another pressure-wise. This means that if you have transmission oil in the coolant, you probably have coolant in the transmission oil. This is very very bad, You will need to have the transmission serviced and possible overhauled to repair the damage. You will also need to flush the trans oil from the coolant system. This will require you to replace the radiator, ALL HOSES as well. Coolant hoses do not play well with transmission fluid . The inside of the hose sort of melts and gets real soft and gooey. Changing the hoses and radiator and flushing the motor should work once the transmissionhas been serviced.

I have a 2001 Ford windstar, I was told while having my oil changed that there was oil in my coolant, yet when my we removed the coolant from the reservoir and waited for it to separate it never did, which...


In my opinion, if you drained the coolant and there was NO OIL in it or any evidence ( an oily film in the reservoir), you were the poor victim of a dishonest oil change facility.

Just watch your coolant and oil level daily for the next week or so. If any milky residue appears on the inside of the cap where you add oil, or any oil film builds up on the coolant reservoir, then you might have a problem. Most likely a head gasket has failed.

when oil mixes with coolant it sill stay suspended for a long time. Water and oil don't mix but coolant and oil will due to the chemical properties of the coolant and it can take days to seperate.

My truck when I slow down the oil gauge is very low and moves up and down. I replaced the oil presssure sending unit and changed the spark plugs. Lastnight I lost heat on my way home. What is wrong with...


Based on what you have written, first thing I'd look at is the coolant level. If low, drain your engine oil and check for coolant in there.
If you find coolant in the engine oil that would explain the changing pressure as coolant will not give you the same pressure reading as oil will..
If there is coolant in the oil it can be coming from either your intake manifold gasket or a cylinder head gasket. To determine which has failed you can have a hydrocarbon test done on the cooling system. If you see white smoke coming from the exhaust, assume the head gaskets have failed and don't bother with any further testing.
If hydrocarbons are present there, then the head gasket(s) have failed.
Also check for external coolant leaks as the two items may not be related.
If no oil is found in the radiator and there is no coolant in the engine oil, have a mechanical test gauge installed and read the actual oil pressure. If the mechanical gauge verifies what you see on the dash, you may have a partially obstructed pickup screen on the oil pump (requires that the pan be removed and the screen be cleaned).
You should not drive if you do find coolant in the engine oil. Coolant is not a lubricant and it will cause damage to the engine bearings...that requires an expensive rebuild or engine replacement.
If you don't understand anything I've written or if you have a question about what you find, just ask and I'll try to answer if I can.

Car overheated once. added more coolant. Now coolant level goes down gradually from time to time, but engine oil seems to be rising. no coolant on the ground that I can tell. whats the problem?


have you noticed some coolant in your engine oil? it will make some bubbles/foam in your oil. If so, the engine head might be cracked and your coolant is mixing with your engine oil. That would explain the reason why your coolant goes down and your oil level goes up.

I have oil in the coolant reservior.


You did not mention what engine you have, so I assume it is a 2.4L and has any radiator stop leak been added to the coolant system lately?

If no radiator stop leak has been added, the good news is you don't have coolant in the oil.
I would speculate you have a head gasket problem. The oil pressure is higher than the coolant pressure, therefore the oil has the abiltiy to enter the cooling system. There is an oil pressure supply galley that runs between the engine block and the cyliner head to supply oil to the cam followers. That is most likly where the oil is getting in.

Unfortunatley the head gasket will have to be changed.
Let me know.
