    1996 Saturn oil mixes with antifreeze and spills out of reservoir. Oil level went from normal to low. Head gasket changed, problem persist. can oil sip in to coolant from the intake manifold? Engine oil is not contaminated with antifreeze. Please advise. Thanks

    I have the same issue. I've taken off the water resevoir to clean the gunk out of it, and flushed the radiator/hoses as best as I could. Car runs fine otherwise...no white smoke, not leaking anything on the ground...but does seem to use oil..I suspect it is leaking into the water at some point. I was also told it was most likely the head gasket...but I can detect no compression issues, or external leakage from the gasket area. The gasket may still be the issue, I'd just hate to replace that, and still have the same issue.

    I have the same problem on a 1999 dodge neon, oil level is low and antifreeze looks like chocolate milk, I installed a new radiator, if it were the transmission cooler it would be low on transmission fluid, car runs fine and gets great fuel mileage. I flushed the cooling system when I installed the new rad.

    I have a chocolate milk like fluid dripping on the area of the driverside front wheel of a 2003 FORD explorer. What could it be?

    Oil in the coolant, replaced the head gasket by experienced mechanic and still had the problem, replaced the head with new OEM saturn head. STILL get oil in coolant! I am at the end of my rope with this car.

Everyone automatically assumes that oil and water mixing means a blown head gasket or cracked engine block. Of course common sense is usually not that common. Oil in coolant is a different problem than coolant in oil. The former is a low pressure leak, and could indicate only an intake manifold gasket. It could also be an early or small head gasket leak. Coolant in oil is usually a cracked block or torn head gasket, and has concomitant symptoms of white exhaust smoke and milky oil on dipstick. If you replace the head gasket and the problem persists, an intake gasket could have fixed the problem.

If you have an automatic transmission then you have transmission oil cooler built into the radiator, any engine oil cooler is mounted infront of the radiator, and there is no possible way for the oil to mix with the antifreeze cause the engine oil cooler is air cooled not antifreeze cooled . follow me , it is possible that you have transmission oil from cooling tanks on the radiator going into the antifreeze yup in order to fix this you need to replace rad its a rare thing for this to happen give it an oil change and check the transmission fluid for antifreeze tranny oil is red in color if its not a nice red then there is something wrong there take a look at things mix a little tranny oil with a little antifreeze by hand just to see what it looks like and mix a little engine oil used with antifreeze just to see what it looks like ok .
sorry i cant help more than this get back to me .also start the engine and let it run to operating temp takeit to the store when you get back pop the hood and look at the upper rad hose and squeeze it if its hard its good theres pressure but if its not hard theres a leak somewhere in the cooling system and its not good possible head gasket

The only place oil and coolant come close enough to being mixed is between the block and the head but the pressure of the coolant is higher than that of the oil so there is no way for the oil to mix with the coolant, Your transmission oil cooling line do run in and out of your radiator, so if your coolant looks like choclate milk you most likley have a crack in the tranny oil cooling reservoir.

Extremely common issue on the 1.9L SOHC Saturn engines. Unfortunately the head is cracked. There was (may still be) a recall for some of these that may pay for this repair.

The head and all associated gaskets require replacement, as does all parts of the cooling system that have any rubber. So the hoses, water pump, thermostat.

Actually this happened to my 1999 Sl1. Sorry to say bot the head gasket didn't work for me so I took it to the shop. Cracked Head was the problem.

Pressure test coolant system, leak down test the cylinders, compression test, and a block test will tell you where the problem is. mechanics are techs, we are trained to see, or hear a problem. descriptions on the internet are a guess. go see a trusted mechanic, and he should be able to help, or fix the problem

Over heating problem


Check the oil dipstick. Some older GM engines have a history of headgaskets. This will be evendent if there is antifreeze mixing with your oil. Has the thermostat ever been changed? Or the waterpump?

White smoke petrol 1.4 renault clio.not stem


White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.



It is also possible to be a engine problem you should immediate visit a car service.

Antifreeze in reservoir is black in color what cause this?


It sounds like there might be engine oil in your antifreeze. If it is oil, then you probable have a blown headgasket. when was the last time you got your coolant flushed and replaced? it could just be old antifreeze. Also, check your engine oil level.
good luck;

Why do I have white smoke coming out the back of the engine by the heater hoses and out my exsaust pipes? Also my car is idleing rough and there is no dexcool in my oil....thanks for your time. Your web...


White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area.

If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.

How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).

Noticed what looks like lithium grease inside the oil fill cap while i was changing the oil..what is it????


this means that you have a headgasket leak flush the system take out the antifreeze fill with just water put in a bottle of block seal / headgasket sealer run the engine for about 3 to 4 hrs then flush out the system again and fill with antifreeze (remember that block seal will clog your system (if) you don't get all the antifreeze out ( read the label on the bottle (autozone carries block seal) about 25;00 bucks
