WHERE DOES ALL THE COOLANT GO?

I have an '08 F350 (6.4, 75k miles) with a coolant leak. There are no visable signs of a leak. I could lose up to three gallons of fluid a day in the cooling system. the oil level has not changed. I have searched this forum and have found some issues that people have had with the EGR valve and cooler, also the timing cover. Is it possible to lose this much fluid in the cooling system and not have any indication of where it goes?. I'm not getting any engine codes, but I do get the wrench with the reduced power warning. There is no indication I'm burning it out of the exhaust. While I'm not familiar with this truck specifically, I have been rebuilding and repairing my own cars for many years. Any direction from forum members would be a big help.

From what you are saying, with no signs of leaks at all and nothing on the ground, I would say it is burning it. I'm no expert on today's emissions exhaust systems, but the system may be filtering it out, (the burnt coolant), better than you think, and not leave any signs of it coming out the exhaust.

Is it only when you are running it? Or will the level go down when it is sitting, not running?

Where did you get the truck from?

My guess is that you just bought it used and it was tuned before you got it and the guy blew the head gaskets and your stuck to clean up the mess.....

I bought the truck back in 2009 with around 10,000 miles. I have never tuned it. Would a blown head gasket pressurize the cooling system or show some signs in the engine oil?. Neither one is apparent in this case.

Yes blown head gaskets would pressurize the cooling system.

Check around your degas bottle you will know right away. If that's the issue you will see stains of it on the drivers side wheel well frame area

I was told that an issue like this could be a bad egr and causing the antifreeze to go out the exhaust, does this have any truth to it?

I am glad to hear you aren't adding oil....that is never a good place for the coolant to go. Personally, I have never heard of losing this much coolant without there being a definite and visible leak. As stated above, if your HG are bad, you will pressurize the coolant so you should have plenty of signs on the cap and degas bottle, hood, driver's side wheel well, etc.. Not sure where you are from so I don't know how much the snow or salt (if you live in a snowy area) could be masking the leak or keeping you from checking everything very close, but have you checked the radiator and hoses really close. They are a very common source for leaking especially with if you don't have the updated hoses. Finally, since you have worked on cars, have you ever built a DIY coolant pressure tester? You can make 1 for under $20 and that will tell you if you are pressurizing the coolant. Keep in mind a blown HG or ruptured EGR can pressurize the coolant. Also, if you use clear hose, you can watch and see if and when you are producing air bubles. If you are 100% positive there are no external leaks, I would be leaning toward the EGR.

How are you checking for codes. If I am understanding you correctly, you are seeing the wrench light and defueling so there should be a code.
