because the block is cracked or a head is cracked. or if you are lucky it could be just a head gasket. Has it overheated?
Oil and water do not mix. oil will float on top of coolant if you remove radiator cap this will be very visible, on the other hand coolant in oil will look milky white.
Check coolant leaks with a visual inspection. Clean the engine, then see where the coolant reappears. Look under the water pump. Check engine oil to see if coolant is leaking into the oil.
The head gasket sits between the head and the engine block if it is leaking out where you can see the coolant, yes you can smell the coolant if it is leaking into the engine no you cannot smell the coolant. You can check the oil to see if it has coolant in the oil if it does then the head gasket might be blown.
Perhaps the coolant was overfilled. It will expand because of heat or pressure and the excess makes it way to the coolant refill tank. Make sure your coolant doesn't have oil in it. In a worst case scenario you could have a faulty head gasket or engine damage that allows engine oil to seep into the coolant. But if you don't see oil in the coolant, then just drain some off.
check your oil to see if you have coolant in it. if you do your intake gasket needs changed.
Oil in the coolant tank indicates a head gasket leak.
head gasket is bad pull the dip stick to see if their is anti freeze in with your oil or check to see if their is oil in your anti freeze
An oil coolant?æ hose is a tube or pipe that allows engine oil to circulate via the radiator in order to cool down. Without an oil coolant hose, oil will get to hot to operate efficiently.
Coolant or gasoline mixed with the oil. The oil light will only come on when the pressure drops. Drain the oil and see if it contains coolant or gasoline. You can smell the gas in the oil. Water will settle to the bottom.
Engine? 3.1L V6 are notorious for intake manifold gasket leaks. get it fixed soon or your engine is at risk. My Lumina had oil in coolant and coolant in oil. If there is tan foamy stuff on oil fill cap, coolant is in oil too.
Could have water (coolant) on it, or oil. If you are worried about a blown head gasket, be less concerned about spark plugs and check to see if coolant is in your crankcase, (motor oil) or vice versa.....oil in your radiator. It is possible for an engine to become hydrolocked, or seized, from coolant in a cylinder with both valves closed. But even if the engine is not seized pull spark plugs to see if there is coolant in cylinder. If there is, bad news. Do a compression check also............David
Engine oil mixing with coolant and/or coolant mixing with engine oil.Losing coolant but don't see any leaks. White smoke (steam) coming out the exhaust that has a sweet smell to it.
