It is designed to be added to the coolant system in the engine to lower the freezing temperature and raise the boiling temperature.

This protects the cooling system itself from damage say from burst frozen pipes and also plays a wuat part in helping the engine remove excess heat. When the two liquids meet, they do not play well. The anti-freeze will stop the engine oil bonding effectively with the engine parts.

That in turn means the engine oil is able to provide less lubrication. There are also a number of chemicals included as ingredients in antifreeze that are not designed for repeated close contact with the engine components. If they are in prolonged contact these chemicals can really do some damage inside the engine. For that reason antifreeze should be removed from the engine oil as soon as possible.

So what do you do haopens it? Well, that will whsn depend on when you noticed the issues, and more specifically if the engine has been started after antifreeze was noted in the oil.

And, is usually caused by, a bad gasket or engine failure. When antifreeze mixes with oil, it robs the oil of its lubricating properties and can destroy an engine. So, antifreeze in oil creates a light brown .

Once I got in and started it up, I knew it was going to be pretty messed up. The engine was knocking , misfiring, and almost immediately going into the red on the temperature gauge! I pulled it in and the first thing I did was remove the radiator cap.

I found the radiator to be bone dry. Wondering where the coolant had gone I raised the vehicle up to check for leaks. It was a high mileage van, so I figured there would be some sort of coolant leak somewhere. Nothing found, just the usual oil seepage and greasy undercarriage of an older vehicle. I filled up the radiator with a mix of coolant and water and restarted the van to see if it would leak, or overheat quickly.

It did start to get hot rather quickly, and I noticed a steady stream of bubbling coolant mix which pretty much told me there was a cylinder head problem. Along with being empty, the radiator and radiator cap were almost totally caked up with a muddy looking substance.

This usually comes from age, mixing different kinds of coolant, lack of maintenance, or oil contamination. A quick check of the oil level dipstick, and I found out where all the coolant went.

This van was no different. They had been driving this way for at least a few months and this was the reason for the misfiring, overheating, and general disarray of the engine. They had an extended warranty , and in situations like this, the warranty company always wants to know the point of failure.

Whether that be the intake gasket , head gasket, or some other internal failure. I had to disassemble the top half of the engine, and the further I got inside, the worse it looked! After removing the intake, I could see the entire inside of the engine, coolant and oil passages were literally plugged solid with gunk.

This basically renders the engine unrepairable, as it is very difficult to clean all that stuff out of the block and heads. The rear cylinder head was taken off also, and it was just as bad. With excessive overheating, the head gasket can blow and even warp the cylinder heads. I could see on the spark plugs and the inside of the combustion chambers that the van was burning coolant. It was bad! That is about the only thing that will fix this one! In the pics below, you can see how bad this engine actually is.

The inside of the valve cover, filled with muck. Same for the top of the cylinder head and valvetrain. Inside the chamber you can see the actual build up of burned coolant on the spark plug electrode. I would recommend getting the car looked at, and put a scanner on it as well. You could have a code for the oil pressure switch, which is easily replaceable. A mechanic can also do an oil pressure test on your car.

It is located in the engine block , below the cylinder head. I would suggest you go over all of your work, including electrical connections, etc. It has to be something you did since it was fine. I have a Ford E cargo van 5. See I accidentally did so the other day as I was refilling my water reservoir but used the wrong container for doing so. Instead of used coolant container like I assumed it was motor oil. Empty but never crossed my head the walls inside of that container would be recipe for disaster.

I knowЕ Please tell me where to start or how to go about repair. I see it all inside my radiator, hoses, water reservoir,intake and throttle body. The harder they are to remove will increase the cost of the labor to do the job.

Also, some of them are harder to get at than others, such as the one located behind the starer. There are also freeze plugs in the back of the engine block which would require the transmission to be removed to install new ones. As you can see, this could end up being an expensive job. I have coolant in cylinder. Head gasket not blown out. Head not warped cant get a. Can head bolts stretch or why would it leak.

You could have a cracked cylinder head. Many times will crack between the one valve seat to the other, but could happen anywhere. Since you already have the cylinder head off, send it to a machine shop to check for cracks. The bolts can stretch.
