Oil mixed with water in coolant

Check your Oil cooler ,which is the aloy mount of the oil filter with two water pipes on. Be Careful first to see whether is the engine oil mixes with coolant and not the Automatic Transmission Fluid if your car is Automatic. If is red colored oil surely is the Automatic Gear box Fluid which is other subject to follow. You have to remove the radiator to renew it or if they have the auto fluid cooler radiator. Good luck.

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.

If it's not moisture, it could be coolant mixing into your motor oil. Check the oil and coolant levels...

have you checked your engine oil if it looks the same?? If your engine oil is mixed/milky colored, then its your head gasket!!hopefully this helps!!

If you are having a lot of white smoke all the time the car runs then check for coolant mixing in with the oil,look for water in the oil when you check the oil or milky brown oil. This produces a white "steam" that is very thick to come out of the exhaust. If your engine temp. gauge is very high and over heats you probably have a blown head gasket. If it has a bluish tint look it may be burning oil. Indications might be how much oil is currently in the car i.e too much oil, or if there is a leak in the line you may be adding a bunch of oil over a short time. If it is only when you first start the car and the engine is cold, then it may be that your valve seals are bad and need replacing.

Somehow water has or is being burned,check coolant level and temp if you have temp light put a guage in if coolant low there is your problem if not check egr valve and pcv valve also check oil level if high and milky there is high possibility that you have blown head gasket and or block may be cracked allowing oil to get into the oil pan.

Hope help (remember comment and rated this).

You better not be driving your car overheating like that and shutting off on you! It sounds like you've most likely lost all your coolant due to a leak of some sort, and your engine is overheating. I would take the vehicle to a shop make sure you don't have some kind of major coolant leak. They'll also want to do a "block-check", which is a fluid that can detect combustion vapors in the coolant, that would indicate you've blown a head gasket due to overheating. It's very bad for an engine to run without coolant, even for 10 minutes. I'd have the vehicle towed in unless the shop is right around the corner. If you'd like to check your coolant level yourself, make sure the engine is cold or at least the vehicle has been off for an hour. Checking the overflow tank level may not be good enough. You'll have to remove the radiator cap and determine if you've got any coolant in the radiator. If not use either regular pre-mixed green coolant, or if you have non pre-mixed dilute it to a 50/50 ratio coolant and water. I wouldn't continue to drive your van with it acting up like it has until you can get it checked out.

CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

This means your car is running too hot. After it cools down check the coolant level and top off as necessary, a 50/50 mix of water and coolant/antifreeze should be fine.

If it it blinks again it is one of two thing, the coolant level is low or the coolant temperature is too high, too high could be an improper water to coolant ratio, i.e. too much water.

Best of luck!

If it overheats - check the radiator that it is getting hot. it's possible the thermostat has failed and is not opening alowing it to cool properly. Replace it if it has failed.

Check that you are not using water/ coolant, or have a leak.
If there is no leak, but you are loosing coolant, first check the oil level - if it reads very high - suspect coolant is getting into the oilways.Or if there is oil in the coolant - it really needsa new head gasket.

1. Check radiator is getting warm when car is warm.
2. Check coolant and oil levels. Unexplained losses , gains or mixing requires a new head gasket.

hi  ernie try changing the thermostate first as this can cause this  D
