Diesel Fuel in Radiator Coolant?????

[Alexis3601]

I own a 2002 F250 with the 7.3L. Earlier this week I noticed that the coolant reservoir was overfilled. I opened the cap and drained out the coolant to the fill mark, replaced the cap and went to work. Today I noticed that the level had again risen to the top of the tank and was overflowing out of the pressure cap. Once at work I removed the cap and could smell fuel in the coolant. In adddition the rubber gasket in the cap had swelled and had to be replaced. Could anyone please help me determine the cause?

You have some cracked/leaking injector cups

Do you know if there is a way to test which one is bad or does all 8 have to be pulled and checked? I've talked with two mechanic friends, one who works for ford and one who just knows it all. The ford mechanic told me that you can't test each one and that the easiest way to repair is to just pull the engine completely out & replace each one. The know it all told me that there is way to determine which one is bad and to fix only that one.

To locate the leaking cups you have to remove the injectors and pressurize the cooling system. The leaking cups will leak coolant/air back. The cup replacement requires some special tools, so you might not want to do this yourself.
