I was already hooked up to the 7k trailer and pissed off. Opened the Degas bottle and found a slight film of oil on top of the coolant. I was getting ready to go up north for 4th of July weekend and I went to check all my fluids in my 06 6.0.

With time and miles, whether you’re towing heavy or just cruising, any debris or solids that you have suspended in your coolant can become trapped and will slowly and eventually restrict the coolant flowing through the oil cooler. 6.0L Power Stroke Diesel - 6.0 Oil in coolant - First post so bear with me. These pathways are smaller than the oil pathways and allow for cold coolant to take the heat away from the adjacent oil pathways. This will result in filling your cooling system with oil which becomes a thick Vaseline-like emulsion which can be very difficult to remove. When one of the layers separating the oil and coolant fails, it will allow higher pressure oil to flood into and mix with the lower pressure engine coolant.While this oil cooler is effective when it’s fully operational, there are two critical failures that can occur: The hot oil comes in from the engine flow through the oil channels adjacent to the cold coolant and flows out and goes through the rest of the engine. PowerStroke International-built, HEUI-fueled V-8 engine used by Ford up until. The cold coolant flows in, then flows through the adjacent channels and exits out of the hot coolant side into the EGR cooler. coolant, and oil filters used today employ a positive filtration principle. It’s important to note that the two fluids are never intended to mix together! That’s bad news for the six-liter diesel. There are alternating smaller pathways that the coolant flows through. While hard to access or service, it has a pretty simple design–it’s called the stack plate heat exchanger. There are large pathways that the oil flows through. It’s hidden underneath the oil filter in the valley of the engine. On top of the engine, underneath the intake manifold.

To better understand the problems with the original equipment (OE) engine oil cooler, we have to understand how it works.įirst of all, it is located directly beneath your engine oil filter. This is typically an indicator that you have a clogged engine oil cooler and can be putting vital engine components at risk. Does your 6.0L have a coolant and oil temperature spread exceeding the Ford specified 15✯?
