![]() ![]() To make this replacement easy, APDTY offers several other parts related to repairing the Ford Super Duty 6.0L Turbo Diesel EGR Problem. Replacing the EGR Cooler requires that the turbocharger and intake manifold be removed. We also carry and recommend the factory original Ford Oil Cooler repair kit, part #3C3Z6A642CA to be replaced at the same time as the cooler. This could eventually lead to failures of the oil pump, fuel injectors and turbocharger problems. A tale-tail sign of your oil cooler going bad is coolant boiling out of the overflow bottle. Without the coolant flowing the engine temperatures will become extremely hot, starting a pattern of overheating failures with the EGR cooler and engine oil temperatures. Coolant first flows through the oil cooler before the EGR Cooler, this oil cooler is known for plugging up and restricting flow to the EGR cooler. With the 6.0L Power Stroke, another problem leading up to the EGR cooler failure is often the oil cooler. This new cooler is re-manufactured and improved by removing the factory fin design and replaced with bigger thicker stainless steel tubes that allow the exhaust gas to cool without the chance of cracking & mixing with coolant which is the main cause of failure on the factory original units.Ģ010-05 Ford 6.0L Diesel EGR Cooler Tubular Upgrade This is the coolant leaking through the cooler into the intake and vaporizing, exiting out the exhaust pipe.ĪPDTY now offers a solution for the EGR cooler problems with a redesigned EGR cooler that has a larger tubing design instead of the original small fin designed (similar to a radiator). As this condition gets worse, you’ll see white clouds of smoke from the exhaust pipe. At first, you may notice just a loss of coolant with no leak. For example, on the Ford Power Stroke 6.0L Turbocharged Diesel you don’t even know there is a problem, just a slow coolant loss. Which seems to be a common problem on most diesel engines. Unfortunately, this system deals with extremely high temperatures which fatigue the metal components causing cracks. This system uses engine coolant to reduce the exhaust gas temperature entering the intake. How does an EGR Cooler work? The exhaust gasses are directed through the Exhaust Gas Recirculation (EGR) System Cooler to remove heat before the exhaust gasses arrive at the EGR valve. That is why the diesel engine requires an EGR Cooler, needing to cool the recirculation of the exhaust gasses to maintain an acceptable operating temperature while complying with federal emissions standards. This also is it’s weakness, due to the amount of heat the engine as to deal with. The diesel engine has the highest thermal efficiency of any combustion engine using this method of heat along with a high compression ratio for better efficiency. Using this style of internal combustion has its advantages and disadvantages. The worlds best, most cost effective Ford Powerstroke remanufactured engines.The diesel engine uses a compression-ignition system, meaning that it uses the heat of compression to initiate a spark-ignition to burn the air-fuel mixture. Doing this might save you a lot of work and money. If one head holds air, then go to the other head and do the same. This is best done if the engine is at operating temp before you put air to the head. If the crack is really small, it may take a couple hours for the pressure to show on the gauge. If that head is cracked, pressure will register. With a pressure gauge in the degas bottle, pressurize he fuel rail with shop air. You can pressurized each head individually by adapting an air fitting to the front of a cylinder head. Many shops want to replace both cylinder heads but there is no need to fix something that isn’t broken. Asheville Engine sells o- ringed cylinder heads which give you reliability without the worry of blown head gaskets. New cylinder heads will fix the fuel issue. If you have diesel fuel in the coolant, you need to buy new heads. When a crack occurs, diesel fuel easily passes into the coolant. The fuel pressure from the injector rail cast into the head (small hole to the left of the arrow) is far greater than the pressure in the cooling system.

Check out which tools you need to change your oil. In this cut away of the cylinder head, you can see a thin wall between the injector bore (where arrow is) and the coolant passage to the right of the wall. Have ever wondered how a cylinder head cracks to allow diesel fuel to get into the coolant bottle in a 6.0 Ford Powerstroke or VT365 International? Here is a picture and description of where they crack. ![]()
